Digital battery

Laptops configured power systems, including rechargeable battery and external DC power. Power in a case, the user can use an external power supply current for laptops, in the absence of food outside the office, and can be powered with batteries. Thus, when the Laptop battery is the key to the base of the laptop, users will need extra attention to him.

 

Tip: If long-term use of external power supply, DC, you can not remove the battery to extend battery life.

 

Small knowledge: the first launch of the battery nickel-cadmium batteries (NiCd), these batteries have a “memory effect”, each charge is required before the evacuation, very easy to use, and soon found himself nickel-hydride battery metal (NiMH) replaced, NiMH Not only is there no effect “memory” and make more per unit weight of 10% of electricity. The IBM ThinkPad R51 battery most commonly used is lithium-ion battery (Li-Ion), it is also ineffective “memory, compared to NiMH per unit of weight gain more power, the price two times higher than the NiMH . In the same weight, these three types of battery that is 1: 1.2: 1.9.

 

1. Good battery usage

 

The phones today are equipped with lithium batteries, but not nickel-cadmium batteries or nickel-metal hydride batteries, as a souvenir, but if you do not or can not be fully discharged the Battery is full of a whole, so every three months on the lithium-ion battery fully charge and discharge approach is very useful. To achieve the fully discharged battery when the Dell Latitude D500 battery remaining 10% must be allowed when the system in standby mode and the prohibition of 3% in hibernation to ensure that the battery fully discharged for actual results . If Windows XP, you can enter the “Control Panel → Power → Warning” label, respectively, click on “Low battery alarm” and “a serious shortage of battery alarm” 2’s “action alert” to delete all options in and then withdrew these two options (Figure), although the shortage of battery power will not be an alert, it will allow the battery run out and eventually shut down all power .

 

In addition, if the computer is not used for a long period, the lithium batteries will be inactive for 2 to 3 weeks through self-discharge all electricity consumed, so again, it should give before using it to recharge. At this point should be charging the battery for 12 hours straight, and the complete charge and discharge the hp 417066-001 battery three times to completely wake up. If a battery of 12 consecutive hours, or after the third cycle of charge-discharge still can not pay, this means that the battery in May were already gone, usually the battery at about 300 to 400 times (400 — 600 times better special) after loading / unloading capacity of the battery is the equivalent of about 75% of the new battery.

 

Little Argument: The view above is the official views of the manufacturers written instructions, is naturally supreme notebook users point of view. However, many users have found an interesting phenomenon that so that when the battery is full, after an hour (do not pull the plug), Zaiqu laptop batteries touch, the result is close to room temperature is because the sony VGP-BPS5 battery is not charging and discharging status. In fact, the circuit of the lithium battery protection with the circuit itself, the goal is to avoid overload and low battery. When the battery is full after charging indicator light went out, the battery is not charging into electricity, and you can then plug the power plug to recharge the battery in the face of what? In this regard, it is also a forum to discuss batteries laptop most intense.

 

2. Precautions

 

To ensure the laptop battery can maintain a better working condition when in use there are some considerations.

 

(1) New bought the fully charged battery at least once a power, then the power exhausted, the second only after fully charged formally. This can not fully activate the chemical effects of lithium batteries.

 

(2) When the laptop using the AC power from the battery when it is best to avoid them, they are responsible. It can be recharged when the best off the laptop, the battery can be fully charged. Also, do not unplug the power load in half-way, and finished 30 minutes after charging before use.

 

(3) If you use the battery, booting after a few minutes, it is preferable not to take over the external power supply, but to let the battery charge runs out after them.

 

(4) Sometimes it is connected to AC power from the battery May not charge, because some providers to prevent battery over-charge cycles and deliberately designed to record, and only less than 95% when apple A1022 battery started charging. In the notebook when charging, if the watch does not cut the battery is already full AC power, because the battery power at this time may be near 80%, it is better able maintain an external power supply for about 30 minutes time-out support to ensure a fullycharged battery.

 

(5) Long term have the battery must be placed in the shade to weaken its internal autonomy, the reaction rate of passivation.

 

In fact, there is not much to take into account the use of the battery of attention to the number of times a cell can use the difference in more people from the battery itself, differences in the manufacturing process, choose the laptop has a good reputation is no doubt in the future long battery life of these guarantees.

 

3. To use the software to perform full and free

 

If your laptop for a while, it can not be filled with the battery or the battery is full can not be used at the scheduled time when you can about the need to fully discharge and recharge the battery to solve the problem. UNI home now includes laptops, including providing the discharge of the CMOS battery and charging capabilities, these operations can refer to a specific user guide to complete the action. Of course, it is necessary to install the software to achieve this functionality, the following update on the procedures with IBM ThinkPad X60 battery as an example of the battery discharge and charge description.

 

First stage: official homepage Download the updated IBM battery program, if necessary based on their own laptop models to choose the relevant procedures, or they may not be the successful monitoring of action .

 

Second stage: In Windows, double-click the downloaded file to be, according to the procedures and prompts formatted disk in the floppy disk, press the Enter key to start the production system after the startup disk.

 

The third stage: In the laptop using the case of an external power supply with this disk to restart the computer, the screen displays the words starting PC-DOS.

 

Step Four: After the boot into the system, follow the prompts to unplug the external power supply, the program will automatically discharge the battery until the computer automatically closed until the completion of the battery so the discharge operation.

 

Tip: In the discharge process on the screen there will be a percentage of progress notes, does not see the spectacle of a zero per cent to finish, and the whole process does not remove disk .

 

Step Five: Wait 10 minutes then the A1045 battery has cooled a good external power supply, the reusing a floppy disk to restart the computer, once the disk in the autoexec.bat file runs automatically update program, and prompts to continue or not. Click “Yes” to return to the DOS prompt, indicating the process of refreshing the battery is full.

 

Step Six: Turn off the computer, but do not unplug the external power has kept the battery power until the green light.

 

With this operation can be performed on the laptop battery deep discharge and charge, which can not recharge the battery to allow it to have longer working hours. However, the overall operation requires relatively long time it usually takes 6-8 hours, and this step was repeated three times for best results, so the whole process is tedious. We also remember not to attend the deep cycle BATCL50L battery for laptop or notebook batteries provide a certain extent.
