Rechargeable Ni-MH battery how long charge

 

Depends mainly charger charging current is really spacious. Take note of the charger output current above, for example, 500mAh, 2000mAh Laptop battery should charge for four hours, then add a drizzle of extra hours. This is usually rapid battery. There is also a slow 100-200 mAh rechargeable empathy with the size of the battery capacity divided by the output current can be drawn.

 

In addition, Ni-MH battery memory effect the battery is relatively low, but not the representatives are not, so the best time to recharge completely discharged, then charge. If it is in the use of the battery, then obviously do not use electricity, such as MP3, uses no power of nature will be arrested and charge re-born. This helps prolong life.

 

The use of lithium-ion battery

 

1, how to charge the battery in use for a new lithium battery should be noted that a period of time after the battery is placed into hibernation, lower than normal capacity at this time, the use of time has also come to shortening. However, lithium batteries can easily activated, as after 3-5 times the normal charge-discharge cycles the IBM ThinkPad R51 battery can be activated to restore normal capacity. As the characteristics of lithium, its decision is almost no memory effect. Mobile phones so that users of the new lithium battery in the activation process does not require methods and special equipment. Not only is the theory that, from my point of view practice from the start on using the standard method of charging that “activation” is the best approach. For the lithium battery “activate” problem, many say, is the cooldown should be longer than 12 hours, three times in order to activate the battery. This “The first three load over 12 hours to charge” was obviously the nickel battery (such as nickel-cadmium and nickel metal hydride) inherited from the argument. Therefore, this argument can be said that the beginning a miscommunication. Lithium batteries and charge the battery nickel and discharge characteristics are very different but also very clear to you that I have gone through all the serious official stressed that the technical information and charge-off will discharge lithium batteries, especially lithium liquid Ion causing major damage. According to the standard load and therefore the best time and the standard method of pricing, in particular, do not make more than 12 hours of ultra-long burden. Typically, the statement introduced mobile phone charging method is suitable for the mobile phone standard method of pricing. In addition, cell phone batteries or lithium charger stops automatically when the hp 361742-001 battery is full load, there is no electricity nickel charger for 10 hours the so-called “trickle” charge. In other words, if your lithium batteries in full, on the white horse is also sufficient. And we can not guarantee that no one battery charge and the circuit characteristics of discharge protection and will never change and the quality of the safety device so that your battery will be of long duration space flight hazard. It is also d ‘another charge against the main reason. In addition, in some mobile phones, charging more for some time, if they do not remove the charger, this time not only to stop charging system will start to discharge — charge cycle. Perhaps the makers of this approach has its own purpose, it is clear that the battery and cell phone / charger is detrimental in terms of life expectancy. Meanwhile, the charging time should be some time, often at night, but our situation to the electricity grid at night in many places, over voltage, but also volatile. As already said, the lithium batteries is very precious, and more that nickel in the electric charge and discharge aspects of fluctuations in the resistance is much less, if this brings additional risk. In addition, another aspect can not be overlooked is the lithium toshiba PA3285U-2BRS battery is not not appropriate for excessive discharge, excessive discharge of lithium batteries is also very unfavorable. This leads to the following questions.

 

2, normal use should be time to start loading in our forums, often see this argument, because the number of charging and discharging is limited, so phone, the battery should be used as much as possible recharge. But I found one on the charge of lithium-ion battery and Table discharge cycle test, data life cycle is as follows: life cycle (10% DOD):> 1000 Once the life cycle (100% DOD):> 200 times DOD is the rejection of which depth abbreviation. Can be seen from the table in May of depth charge and discharge times, 10% DOD cycle life when the DOD of 100% for much longer. Of course, if the equivalent of actual costs to the total capacity on 10% * 1000 = 100100 * 200% = 200, one full charge and discharge, or better than some, but not before friends say some changes: Under the normal case, you should have a standby battery power is left in accordance with the principle of charging the short load again, but if your battery in your first two days can be expected to persist throughout the day, when they should start on time charge, of course, if you’re willing to back the charger to the office again a different issue. And you need to recharge in order to cope with the communication provided lead busy to come to an important event, even if a lot of apple A1022 battery power over time, then you just charge ahead, because you don ‘are not really lost, “as a” life cycle support is “0.x” times only, and that x is often very low. Short on battery and then filling the rest of this principle is that you want to go to the extreme. And long as charging a widespread view that “as far as possible the cell phone battery power runs out, it is preferable to use automatic shutdown.” It’s really just practice for nickel, the goal is avoid the memory effect occurs, unfortunately, it is also spread of lithium batteries on this. It was too low because the cell phone battery warning appears, still do not charge to continue using the example has been used in automatic shutdown. The results in this case, cell phone charging and starting later in the answer no, should provide review services to clients. In fact, it is because of the battery caused by excessive discharges of electricity at low voltage, so that was not the normal load and footwear and conditions.

 

3 phones for lithium batteries good way to sum up, I lithium batteries used in mobile loading and unloading, the most important recommendations are: (1) in accordance with standards and procedures, charging time, even the first three have to do, (2) when it is weak advice cell phone battery, you should try to start charging a timely manner, (3), lithium batteries do not need ‘ enable the special mode, a battery of standard cell phones use lithium is naturally activated. If you insist on spreading the use of “three previous 12-hour long activation charge” approach, in fact, there will be no effect. Therefore, the pursuit of all super-long 12-hours lithium rechargeable Aspire 3000 battery cell phone use and integration of the practice of automatic shutdown, are wrong. If you’ve already done under the argument wrong, please correct time, perhaps not too late. Of course, cell phones and chargers to protect themselves and the circuit control for good quality, protection of lithium batteries is still guaranteed. Therefore, the burden is central to understanding the rules and, in some cases also may make some concessions. For example, you find your cell phone the night before bed charge, you can also start charging before going to bed. knot of the problem, you need to know what good thing, and not deliberately wrong to do so in accordance with.

 

Battery Maintenance:

 

We know that the cell phone apple A1060 battery is a source of electrical energy, which is the driving force of mobile phone, there is no mobile phone battery is one piece, high capacity, high performance batteries, not only for cell phone long battery life, but also protect telephone circuits to devices that can operate effectively a long time, and vice versa, is likely to cause unexpected damage to mobile phones. For us players, the performance of the battery when the factory, it had already been determined, the size of its capacity, performance, good or bad, are determined by the cell itself and in this regard, we can not man-made changes, but this does not mean that we get the battery after it has produced it should not be done. The use of mobile phones are lithium-ion rechargeable batteries used to store electricity is consumed, need to be added once the feedstock. Do not look down on charge of this aspect of a good shipper and the correct method of load can keep the battery long wait time, but also extend battery life. No more, says mobile phones can also play a protective effect.

 

Methods on how to charge, often in the forum, players will be invited, after a period of actual use and reference, I have summarized the following points:

1. Lithium general factory, manufacturers enable the processing and pre-charge the batteries have more than electricity, you can buy a new cell phone battery is a lithium-ion toshiba PA3285U-3BRS battery, then the first 3 to 5 times charged as a period of adjustment, should be sufficient for more than 14 hours to ensure complete activation of the lithium-ion activity. Lithium-ion battery without memory effect, but a strong inert, should be given to fully activated to ensure that used to achieve best performance. The first charge on this issue, I also consulted the technical staff of Samsung gave me the answer is Samsung original battery, the factory has already been done before the full activation of the treatment, then it does not a long way to activate the charging lithium-ion activity, the first rechargeable battery inside as long as I can be filled after the consumption of electricity. I would like to Samsung’s technical staff should be able to claim convincingly.

 

2. Some automated intelligent rapid charger when the lights change direction, but only said he was full of 90%. Charger will automatically change with the slow loading of the battery is full. Do not immediately cut off the charger, the best should be given to supplement the battery for a while, the battery is fully charged before use, otherwise it will shorten the duration of use. 3. Before charging, lithium batteries do not need to assume, can not fulfill the current production of hp F2024B battery charger lithium is impossible to perform functions, so you can adjust the speed of loading, then suggest that you try to slow Chong Chongdian pricing to reduce the fast charge mode: either slow or fast charge fee of more than 24 hours. Otherwise, the battery is likely to spend long hours of power have an enormous flow of electrons and burning batteries.

 

4. There are many users in charge when the phone open, in the process of charging, the battery side because of the use of mobile phones in landfills, and also because the battery while the assets of Supply disruption of power supply is likely to result in the councils of cell phone circuit will be fever, if an incoming call will result in an instant return current to damage the internal parts of the phone.

 

5. Battery determined by the number of repeated charge-discharge, lithium batteries can continuously charge and discharge of about 500 or so after the battery performance will be significantly weakened, and must try to avoid all batteries I put an end to the rechargeable power, or with the load increase in the battery performance will gradually weaken, the battery reserve time it would be difficult not decreased.

 

6. Do not expose the battery to heat or cold, as a day dog should not be placed on a mobile phone under the sun, and withstood exposure to hot sun, or get air-conditioned room, the air conditioning blowing right places. Loading, the current return, the battery a little fever is normal.

 

7. If the mobile phone battery to attach too long without employment, it is best to call the maintenance department to apply on the drums for an activation treatment, you can own devices with a constant voltage direct current, by adjusting the voltage of 5 ~ 6V, current 500 ~ 600mA reverse battery connector. Note that the liberalization of touch, most can be repeated three times, after such treatment, re-use original charger “adjustment” charge.

 

8. The higher the load is not good, not protecting the circuit fully charged battery must be stopped immediately, otherwise they will have an impact on performance due to fever or overheating. Theoretical calculation of IBM ThinkPad R52 battery charging time is as follows: power battery charger, divided by the output current can be, for example a 800mAh battery, for example, the charger output current 500MA, then the time load is equivalent to 800MAH/500MA = 1.6 hours, of course, this is a theoretical calculation of time is full of power, while the charger shows charging is completed, preferably about half an hour or and should be given to the size of the battery power-up time. Dedicated lithium-ion battery charger must be selected, or they may not reach saturation, the impact on its performance.

In the 21st century, the world’s energy saving problem of reducing emissions is very important, while the height of the information age of high automotive, high technology, good conditions for the development of another, so that the global automotive industry, appeared in two types of innovative ways: First, attach importance to technology to traditional internal combustion engine vehicle a significant improvement, the second is actively engaged in developing new energy vehicles, particularly the development of electric car development and industrialization. Electric Vehicles and vehicle fuel cell in the global automotive industry, the future development of vehicles and the theme for the competition and electric vehicles as a key vehicle batteries to power new car, auto giants are and the reasons leading manufacturer of Laptop battery, but they have announced investment plans and production workload, triggering a boom car battery investment.

 

Electric vehicle batteries on board a new energy

 

The overall development of electric vehicle battery technology in two major aspects: first, the two existing time the battery should be improved; second is to develop new fuel cells. Currently the majority of electric vehicle battery is still at relatively cheap price of lead acid batteries and other traditional products, but with technological advances and cost effective control of production, batteries lithium and nickel-light metal hydride battery, mileage long life and high energy density and production benefits are gradually being power, which will become the heart of development. Experts predict that by 2015 the global market demand for batteries of hybrid cars will increase three times with a total value reached 23 billion U.S. dollars in 2009, first used in hybrid cars on lithium-ion batteries may occupy the entire half of the IBM ThinkPad X60 battery market. Japanese car giant is expected in the United States and Europe around the year 2010 will be officially in the lithium-ion batteries on passenger cars.

 

1) The vehicle fuel cell on demand. Fuel cells use a variety of fuels, which may be petroleum-based fuels, can also be an organic fuel, and can use, including renewable fuels, including virtually all elements of hydrogen fuel. Been transformed into hydrogen fuel, with its hydrogen fuel cell fuel cell conversion of fuel energy law Carnot cycle limit, thermal efficiency can reach 34% ~ 40%.

 

Different types of fuel cells use different electrolytes are acidic, alkaline, molten salts or solid electrolytes. In the fuel cell fuel and oxidizer through the catalyst in the process of energy conversion, production of electricity through the electrochemical reaction and water (H2O), therefore, does not produce ‘oxides of nitrogen (NOx) and hydrocarbons (HC) and so on air pollution emissions from the environment.

 

Currently, for the combustion engine powered vehicles has become one of the harmful gas emissions, the main source of emissions. Experimental Evidence: When the new vehicle to use natural gas, hydrogen fuel cells as fuel VGP-BPS9 rather than gasoline engines, internal combustion, CO2 emissions can be reduced up to 72%. However, if fuel cells replace the internal combustion engine, the technology of fuel cells, not only to comply with strict legislation on emissions vehicle requirements, but also provide the same convenient and flexible for users end transportation solutions. Drive vehicles, fuel cells must be able to quickly reach operating temperature, with economic benefits and can provide stable performance. It must be said cell proton exchange membrane fuel is best placed to meet these requirements, lower operating temperature can quickly reach the required temperature. As can quickly adapt to a variety of different needs, and about 25% of the efficiency of internal combustion engine, compared to their effectiveness can be as high as 60%. Studies have shown that cells with methanol fuel, fuel consumption is to use gasoline for internal combustion engines of vehicles to 1.76 times. In the existing fuel cells, fuel proton exchange membrane cell power density of the most important. When people in the vehicle for special attention to the design of space is maximized, this factor is essential. In addition, the solid polymer electrolyte may help reduce potential corrosion and safety management. The only potential problem is the fuel quality to avoid contamination of the catalyst at low temperature, fuel cell proton exchange membrane must be used without polluting hydrogen fuel.

 

2) Lithium-ion batteries and lithium-polymer and objects (LIP) battery. Lithium-ion battery (Li-ion) batteries developed from a lithium Dell Inspiron B130 battery. Material Lithium MnO2 cathode or thionyl chloride, lithium anode. After completing assembly of the battery is the battery voltage at no charge. This battery can be charged, but the cycle performance is not good in the charge-discharge cycle over the formation of lithium dendrites, causing internal short-circuit the battery, under normal circumstances the battery Management is prohibited. Later, the Japanese Sony invented the carbon anode materials, lithium-containing compounds to make positive, the charge-discharge process, there is no lithium metal and lithium-ion does, which is Lithium-ion battery. When the battery is charging, the lithium positive ion generation, resulting in movement of lithium ions through the electrolyte to the cathode. As the anode carbon multilayer structure, it has a lot of micro, lithium-ion anode embedded in the porous carbon layer, the integrated lithium-ion plus more carrying capacity. Similarly, when the discharge of the battery (ie, the process of using the battery), which is incorporated in the layer of carbon cathode of lithium-ion extrusion, but also the movement back to positive. Back to the cathode of lithium-ion battery plus the largest discharge capacity. Commonly called “battery capacity refers to the discharge capacity. LII and LiP battery is the newest technology batteries, lithium chemical processes involved in organic electrolyte ions Li in the carbon anode in lithium metal and lithium compounds, running between the cathode. Developed by LiI batteries using cathode lithium cobalt oxide (LiCoO), the negative is very high capacity hard carbon online carbon material to form a single cylindrical cell (diameter 67 mm, length 410 mm) by set of eight composition of a standard component. Weight 29 kg Voltage 28.8 V, capacity of 100 Ah, the specific energy of 100 W? H / kg. Only charging voltage of 4.2 V hp Pavilion dv4000 battery, full-time load is 2.5 h, the power density of up to 300 W / kg, to about Ni-H 2 times. LIP is a state of “solid” battery, which uses a lithium metal or pure lithium in the carbon anode, the use of high conductivity of the solid polymer electrolyte. The unique nature of the electrodes for lips and polymer is very thin, the thickness of a unit is only 0.01 cm, the equivalent of a “transparent tape” thick. May be packaged in any form, can drive and installed in the cylinder, may also piled up a block of apartments. LiP unit battery voltage 3 V (NiMH battery 1.2 V) so that 12 V batteries lip may be composed of four single-cell battery 14 V Lip.

 

Canada Hydroquébec Electric Company and 3M, the joint development of the lips for the batteries of electric cars to work at 60 ℃ to obtain high conductivity in solid polymer electrolyte, so that better performance of the battery, its energy density 120 W? H / kg. Nissan Hyper Mini electric vehicle using high density and light quality lithium-ion batteries, their energy density batteries, lead acid 3 times, 1.5 times the nickel-metal hydride sony VGP-BPS5 battery can load and unload 1 200 times. Load simple, non-contact charging method, you can simply roll the plastic into a high output power of ordinary frequency, you can connect. Massachusetts Institute of Technology (MIT) have developed a new type of cathode materials for lithium battery, lithium batteries can produce lighter and prices lower, while the energy conversion more efficient. Using a replacement aluminum parts are usually made of cobalt cathode, the lithium produces a higher voltage than normal. As the density of aluminum small and inexpensive, thereby reducing the quality and cost of the entire battery.

 

3) Ni - MH battery. It is also a type of alkaline batteries, the nominal voltage of 1.2 V, the specific energy can reach 70 ~ 80 W? H / kg, will extend the mileage of electric cars. That the power of 200 W / kg, is the lead acid batteries twice may improve the performance of starting the vehicle, and acceleration. Features a high discharge rate, a short period of time can be 3 C discharge, the instantaneous rate of discharge pulses much. Ni - MH over-charging and over-discharge performance is good, may be responsible charge and can fast charge, within 15 minutes in up to 60% charge, 1 h may be completely filled in the additional period of Emergency care is short. In 80% depth of discharge, cycle life can reach 1 000 times more than lead acid batteries 3 times. All closed-shell, you can work in a vacuum environment. Better performance at low temperature can be stored longer. Ni - MH are not heavy metals like lead and cadmium do not pollute the environment, Ni - MH toshiba PA3191U-3BRS battery can be charged with leaving it with no nickel - cadmium in the absence of discharge after finished charging electricity to the “memory effect”.

 

2-car electric vehicle battery is the bottleneck technique

 

The ultimate development of the new direction of energy vehicles purely electric vehicles and electric vehicles to fuel cell, while the current market outlook is the most hybrid electric vehicles and plug-in hybrid electric vehicles (PHEV) especially the broad perspective PHEV, its maximum technical difficulty is precisely the vehicle battery. Pure Car battery is running in bus lanes, and some carmakers are beyond the pure cell prototype car, but because the level of battery power and price reasons, not in the car on a wide range of applications . Vehicle fuel cell are currently part of a basic theory and practical skills while promoting high-tech products, while the global automotive industry, a more coherent vision, from a historical trend and realistic to consider the scientific development, it will be the future of the electric car industry is also the best final product. Currently, a fuel cell powered electric + electric hybrid car has more to occur. This will temporarily reduce its technology to fuel cell requirements of lithium-compensated ion apple A1079 battery, it can be said that hybrid vehicles in the longer term transition, leading to a real cell vehicle fuel is an issue course. Hybrid technology is an important part of the strategy for energy research and development of automotive batteries, countries are wrestling competition to advance a breakthrough. In 1991, the U. S. General Motors, Ford and Chrysler have created an electric car “Advanced Battery Consortium (USABC), co-developed needs a new generation of high-energy batteries and heavily subsidized by the U.S. Department of Energy. In recent years the government U.S. has also provided 3 100 dollars to accelerate research into this technology. The foreseeable future, new energy vehicles PHEV is an important development direction.

 

3 warlords market investment vehicle battery becomes mainstream lithium batteries

 

In the field of lithium batteries is the global market share of first place in Sanyo Electric of Japan to start mass production in 2009. From the beginning of 2006, Sanyo to join the Volkswagen Group in Germany, a new generation of nickel - systems hydride batteries. Volkswagen is currently jointly developed specifically for hybrid vehicle battery high capacity Lithium, and is ready to be in 2012, the use of vehicles environmentally friendly. Toyota Motor Corporation jointly Matsushita Electric Industrial Co., a substantial increase in the Aspire 3000 battery environment friendly hybrid car. Toyota and Matsushita Battery co-funded manufacturing enterprises “PanasonicEV energy (hereinafter PEVE) will build a mainstream production of nickel - plant hydride batteries, the large investment of about 300 billion yen is expected to put into service in 2011, an annual production capacity of around 300,000 car batteries. This series of initiatives to increase the total investment of about 700 billion yen. At the same time, Toyota also accelerate research and development at a lower cost mass production of next generation lithium-ion battery technology. PEVE will invest in new production of next generation lithium-ion battery plant, and strengthen the existing installation Ni - MH battery capacity. These measures will accelerate the environmental strategy and achieve Toyota hybrid production to reach its global vehicle output 1 / 10 targets.

 

To catch up to Toyota, Nissan and NEC have started joint production of car batteries. Nissan and NEC will jointly cost 20000000000 yen (about $ 194 million) in the mass production of the first world of hybrid cars and electric vehicles and other environmentally dedicated lithium-ion batteries. The new joint venture plant in early 2009 formally put into operation, the initial production of lithium batteries will be able to provide 1 million hybrid electric vehicles use, future production will increase by five times. Nissan began in 1992 on board lithium-ion VGP-BPS9A/B battery research and development. 2000, the company co-operation with NEC to jointly develop lithium thin-ion battery technology. In May 2008, Nissan Motor and NEC and its subsidiaries NECTokin joint venture company - Automotive Energy Supply Corporation (AESC) began operations around the same time, Nissan and its French partner Renault to provide the lithium battery. 2 shots from 2010 in Japan and the U.S. market for electric cars.

Development of electric cars and hybrid vehicles in the automotive industry in energy shortages in the world and its changing lifestyle need to find a way out of your move. Europe and the United States on alternative fuel vehicles in the current development of new energy is different. Characteristics of the island of Japan geographical influence their consumption habits, has developed a new bus station and convenient charging for development for the city driving a small electric car for the entire national acceptance.

 

4 Conclusions

 

Currently includes the Toyota Prius hybrid cars, including the use of Ni - MH VGP-BPS13 battery, but the efficiency of the battery technology is regarded as having reached the limit, while the lithium-ion batteries due to have a low light weight, high capacity and high power and other advantages of being in North America, Europe and Asia, auto makers favor, is expected to field lithium-ion batteries will also gradually replace nickel - hydride batteries. Currently, the leading countries have a deposit of more than 20 lithium-ion battery research and development, while Toyota and Ford and other carmakers are clear that the future of its hybrid car will use lithium-ion rechargeable battery.

 

The future increase in demand for portable devices, and can be multi-processing task in recent years, the average consumer to use “small parts” of the market expansion will promote the growth of lithium batteries ion battery market, light electric vehicles and electric vehicles and other new applications are for the lithium-ion battery in the dynamic high growth industry and the car lithium-ion battery market next 5 to 7 years continue to grow. 2016 value of total production of lithium-ion battery market is expected to challenge 10 billion U.S. dollars, the lithium-ion batteries are also broad prospects for developing lithium-ion battery room huge industry electrolyte imagination.

Introduced the use of nickel-metal hydride battery of new products also accelerated the acquisition of all the heat, of course, it is unique “temperament” as the energy density, the number of charge cycles and more details ‘memory effect is small, non-toxic metals such as cadmium, mercury are also a number of advantages achievement of nickel-metal hydride Laptop battery position in the bull market.

 

With all the hands in nickel-metal hydride batteries steadily increasing number of scientific leap in the use and maintenance has gradually at the sight of attention. As we all know, the brand Ni-MH IBM ThinkPad R51 battery life can be charged according to the official request that 500-1000 times, but this is actually a good value, and often do not respond to such a life. But as a sensible use of chargers, more in depth understanding of nickel-hydride batteries, metal, we have left to do, “longevity”.

 

1. Under normal circumstances, the new nickel-metal hydride batteries contain a small amount of electricity we buy on driving charge and then reuse. However, if time battery plant is quite short, electricity is sufficient to recommend use first and then reload.

 

2. The new nickel-metal hydride batteries to buy a general charge to go through 3-4 times and use of, performance can play in the best condition, many of my friends for the first time, the prosecution encountered a small problem, for example, the first charge did not imagine the number of PP film so many? In the 3-4 times after charging and the use of all be resolved.

 

3. Although nickel-metal hydride Dell Latitude D820 battery memory effect is small, as much as possible is recommended after each use finished loading and is full of time, do not charge you would use for one count and then. Only longevity, “Oh, the important point.

 

4. The battery charging, the charger should pay attention to the heat surrounding the deliberate use of what wind there too is no need for fans, but noted that the shipper should not put too much debris around. Ordinary users the process of using the battery, the battery is often not a dedicated storage bag; users to replace the battery, will acquire the habit of easy storage battery, regardless of where the place is clean and moist . The consequence is that the battery they get dirty easily, easy-to-metal contact, such as keys, etc. contact, easy to moisture, and it is the enemy of batteries. Recommendation: Users should set up a special cell to place points and keep the battery clean. To avoid problems such as loss of electricity to keep the Dell KD186 battery and contact points of the battery to both ends of the inner lid clean, if necessary, use a soft, clean and dry pasture.

 

5. A long time did not have time, remember to remove the battery from the storage battery, placed under dry conditions recommended brand of battery in the box to prevent short-circuit the battery.

 

6. A long time without nickel-hydride batteries in the metal shop a few months later, the battery naturally in hibernation “state”, the battery life considerably reduced. If Ni-MH battery has been placed for a very long time, I suggest you begin with the slow charge is appropriate to impose. For another important issue at stake here: for Ni-MH HSTNN-LB31 battery, the battery must be completely discharged, then save, store, or online? Both points of view very different from what it should be used? Many people think that we should adopt the first, but I thought that to save the battery charge is reasonable. Because: According to tests, Ni-MH battery to save the best conditions to save about 80% charged. Because the nickel-metal hydride batteries self-discharge rate is high (10% -15% per month or almost), if the battery is completely discharged, then save it for a long time not to use the ‘battery-discharge phenomenon will discharge excessive battery, may damage the battery. Do not believe? So you think to buy a new nickel-metal hydride rechargeable battery is not all there is electricity, which is the reason. Recommendation: Apart from correcting the wrong point of view, maintenance of the battery to start in the right direction, otherwise it will backfire.

 

7. There are many messages from friends post questioned how to meet Ni-MH? After investigation, after many specialists battery reach a unanimous conclusion to remind friends. Do not nickel hydride metal discharge the sony VGP-BPS2 battery, excessive discharge may cause the failure of pricing to harm is much greater than Ni-MH battery memory effect of the battery itself!

 

8. Auto multimeter test battery is full or not. Ni-MH batteries in general charge before the voltage is below 1.2V, filled with normal voltage is 1.4 V or later. We as a judge, also very easy to judge the condition of the battery.

 

9. Chargers can be divided into fast charge and trickle charge. Low load current is small, typically around 200 mA, such as our common load current is about 160mA. His long-time charge, 1800mAh Ni-MH toshiba PA3399U-1BAS battery should be 16 hours or more. Even if I was a little slow, but the charge would be filled very full, and do not hurt the battery. Fast charge current is usually in the more than 400mA, charging time significantly reducing the number of .3 to 4 hours can manage that, but also won the affection of all. Several types of fast charge, prices vary. Therefore, we often have questions about the same load faster, why the price is a big gap in it? Good charger in particular is a good fast charge brought against over-charging protection function, for example, we have a common understanding Acura Panasonic BQ 390 charger has been particularly noteworthy in this regard, excellent software chip capacity charge the battery while it also brought evil upon the battery, quick charger minimized.

 

10. Conflict: trickle charge does not hurt the battery charging time is too long, however; fast charge can save time, but there is damage to the battery, even if the surface is the world need the best degree Panasonic BQ390 charger only very good harm reduction, but not totally avoided. Contradiction can be resolved is to buy a quick charge and a trickle charge. Quick charge with the load for some time, for example, 5.10 times after the transition to slow Chong Chongdian once or twice. This apple A1078 battery performance to return to a higher state.

 

11. The batteries are commonly used battery, four or six, and this time, to maintain the balance of each cell is very important, otherwise, due to a battery problem has affected the work of the entire battery. First, the battery capacity and ensure consistency, the best place to buy the same brand of the same type of battery time. Then the internal battery power to maintain consistency, simply, is that the electric battery is either full or empty. If there are more groups in the composition of the battery, you can try to “select” look. Means that the specific capacity, similar to the battery voltage and other parameters in one set of battery cells in series, due to poor conditions, under normal circumstances let endpoint measures after the tension and son of red blood on it.

 

12. Speaking on the last charge and discharge.

 

Top of the range of NI-MH Aspire 3000 battery charger with battery test delta-V to determine if the battery is full. When the curve of discharge voltage of the battery and is somewhat similar to the beginning of a more rapid rise, followed by rising slowly until the stuffing is good, the tension began to decline rapidly, but decrease in not very large. Before commonly used nickel, cadmium batteries are also similar, but drop the speed and the amplitude was higher than the NI-MH. Most chargers on the market type (less expensive) is often used is the value of the charge pressure, such as the elderly GP 1.4V Rechargeable value Po is the pressure that is precipitated at 1.4V when the battery voltage, because there is no difference, and charge on the end. Such a result is often that the battery can not be bridged, particularly in some older battery due to increased internal resistance, the real addition to the low voltage battery. And this charger currents tend to be smaller, often charging more than 10 hours. Using Delta-V cutoff automatic charger, since it can precisely control the load time, use may be more reliable high-current load. High charging current nickel-metal hydride battery for damage and do not want to imagine the contrary, the use of DC current, but also require high current load. The first is a matter of time, not talk. Then, Ni-MH battery has a characteristic, that is, the higher your current rate, it can release the most common, and now is tigre DC electric current is not small, so relatively speaking the use of relatively large load current is a choice, you can clean the toshiba PA3191U-4BRS battery is added. General 5 charge current should not exceed 1.5 C, C to the battery capacity is 1000MAH batteries, not more than 1.5A. I usually carried with the load 0.5C (my charger with adjustable current). Discharge zone, in normal circumstances, DC Black can be a burden on Na Qu, NI-MH little memory effect. However, in a period of time after use, and the balance of the cell to activate the battery when the battery discharge and control the termination voltage. NI-MH battery termination voltage of 0.9 V, the discharge time careful not to over-discharge, the 0.9V for each battery when it may stop the rejection file. NI-MH battery is not powerful nickel-cadmium batteries, the overcharge and over discharge and is more sensitive to high temperatures. Charge and discharge temperature. In general, do not let the hp F4809A battery temperature exceeds 45 degrees. When the battery is fully charged, the battery will be hot, filled with large current when the temperature is 42 degrees and not more than 45 degrees, otherwise life will soon be reduced, the battery internal resistance will increase. Also, the load of the battery temperature is higher, and so on until after the cooling of its rechargeable battery, charging money for having to wait for the freshness of the battery. After a long time is not re-using, it is preferable to activate the battery to discharge a few times. Usually used in time to pay attention to maintaining the integrity of the wrapping paper, can not be broken in order to prevent short circuits. Do not fight the impact of the battery, do not fire and so on.
