Digital battery

Portable using a period of time longer prone to the problem of declining capacity of the battery, leading to the life of the battery cell shortened. This is essentially internal batteries or battery failure caused by aging. In severe cases, the use of calibration procedures of the Laptop battery or the battery charge and discharge are repeated to solve the problem. For this issue, there are many fans that the shell of the battery opens, find and replace the batteries may be unable to solve the problem. The current situation is really the case?

Replacement batteries must be cautious

Since the laptop is now a greater use of lithium-ion batteries, while the life of lithium-ion battery is essentially constant, and its battery life of only 500 to 800 times. Therefore, if often use battery-powered laptop, later, 1 ~ 2 years, the battery is easy to achieve because of the internal life of the batteries fail. As we open the battery when the battery test is represented in one or two batteries damaged. However, due to other cells that is about it, even if you replace the batteries fail, the battery can be quickly returned to normal, will soon fail for other batteries and battery life can be full used again.

Then, all of the laptop Dell Latitude D820 battery to replace all the internal capacity to solve the problem? In fact, it’s hard. Because in the original cell, after its internal batteries game specifically, if the battery capacity, the terminal voltage and internal resistance of the consistency property. We bought on the market in batteries, and have not been tested and matching, we can not for the amateur conditions, combined batteries, so its capacity, internal resistance and other parameters vary inevitable. In the internal battery, batteries are in series between them after the load (in most notebook battery, is 8 cells were divided into two groups, four in series and then parallel to form a battery pack) due to the battery charging current from which the smaller capacity batteries will be the first total power, but not enough because the other battery, the battery terminal voltage can not create voltage load circuit will continue to charge the battery pack. In this way, the batteries supply the original track will be overloaded. To reduce the charge time, laptop charging circuit load current is very high, so will charge batteries when the tremendous heat, so that the batteries inside the liquid temperature increases, pressure increased, the internal electrolyte easily dry up or overflow, leading to a further decline in cell capacity, there is a swelling or even an explosion. The total capacity of the battery capacity by the decisions that smaller batteries, so that would create a vicious circle, after repeated charge-discharge capacity of the whole battery would be considerably reduced, which leads the ‘Time use laptop.

At the same time, a number of laptop batteries to prevent unauthorized users from opening to replace the batteries, has a microchip and an anti-line off Cape. As the hull of the hp 417066-001 battery or batteries to open the line of the battery Remove the card and smart circuit protection will cease production of the battery. Even if we re-take the battery circuit of the battery and close the battery chamber, its smart protection is still not recovering. In this way, the battery will not work out. We need to re-reset the smart chip to solve this problem, but a condition amateur can not reset the chip to chip. Therefore, replace the batteries when the battery can cause permanent damage.

So how can we solve the battery problem? The best way of course, is to buy a new battery of origin, but now a new original equipment batteries for hundreds or even thousands of dollars, this cost is too high, higher than many consumers can afford. However, there are a number of professional station laptops repair, equipment and technology are good, but there are repair stations and manufacturers of batteries existence of long-term cooperative relations, the VGP-BPS8 battery can be made corresponding precision. This would maintain the quality. In these places for the price of batteries is about 300 yuan, although it compares to replace the batteries of their own at higher prices, but it can protect the long-term use of the battery. In addition, some service stations are also carried out repairs for six months before the battery warranty. We use these six months, while there are a hundred times or two to ensure the battery charge and discharge, and battery capacity and stability during this period, then after the battery is about to enter a stable period is not easily damaged.

The trick to keep the battery

In any case, replace the batteries do not require us to pay a little more, so we must be aware in their daily use to maintain the battery to extend battery life. To protect the battery, first reduce the number of battery, which means it is electricity to the extent possible not to use the toshiba PA3399U-2BAS battery. This can reduce the number of loading and unloading of the battery to extend battery life. Although this use to a few drawbacks, but think of you each time you use the battery, it must pay two dollars, be prudent in the summer bar.

Calibration procedures battery can extend the battery life has been a debated issue. Support of people think that the calibration of the battery can eliminate the memory effect of batteries to extend battery life. Opponents argued that now use lithium-ion batteries have no memory effect, if the correction procedures will only increase the number of loading and unloading of the battery and shorten the life of battery. In fact, two types of agreement are incomplete. While the reduced lithium-ion battery memory effect, but the memory effect still exists. Calibrating the battery may actually reduce the memory effect, but this is not the most important function of calibrating the battery main procedure is to establish the battery and control circuit, in order to optimize the control circuit can correctly identify the capacity of the battery to avoid overcharging or over-rejection phenomenon. At the same time, you can also ensure that the apple A1079 battery is exhausted before the system closed to protect data security. However, frequent use of calibration procedures of the battery would indeed increase the battery charge and discharge time. Therefore, we once every three months or if the calibration procedure of the drums on it. We use energy from the battery when the laptop or adapter to charge the battery, disconnect the battery cell. Regardless of the battery is charged or discharged state, the current is very important if we try to connect the battery, it is easy to produce electrical sparks, not only will the removal of contact, the impact of the current May also cause the board of the battery or system portable charging circuit damage.

In addition, many people there are some misconceptions about the use of the battery. Such as “newly purchased batteries need to go through a few charge-discharges to enable,” “laptop battery needs to full output:” In fact, Li-ion battery memory effect with the reduction and improving battery protection circuit internally. These factors affect the capacity of the battery was very low, and we only run the calibration procedures of battery on a regular basis will be able to eliminate the impact of these Operations on the stack, we must not wait for that, and that more carefully your laptop, after all, the battery is presented useful.
