Mainly two things about laptop battery maintenance

Now, people increasingly use the laptop as a laptop, one of the main components of lithium batteries will also increase the problems. So how should make good use of laptop batteries to lithium? Mainly to take two things:

   (1)  An appropriate charge-discharge;

   (2) To minimize the discharge less than the load or discharge. While the Laptop battery is a consumable, lithium-ion is no exception. But nobody wants the durability of the battery, following the battery began to speak. Firstly, to explain who is limited to lithium-ion battery.

The general literature and the country on standard lithium ion lithium-ion batteries on said load current must be between 0.2C to 1C. This is expressed by the load capacity of the battery current, such as your battery is 4AH, then the 0.2C charge current is 0.2 × 4 = 0.8 A, which is the load current must be between 0 8 to 4A.

In general, the charging current to the extent permitted by the smaller the better, rechargeable lithium, ion VGP-BPS2B battery should be the beginning of a constant current charge to IBM R31, for example, the current is 2.8A or more equivalent to 0.7 ° C, is charging circuit to control their own and can not set ourselves.

Although such a charge indicator does not exceed the requirements of the standard, but not relatively significant, especially when the battery capacity decline for some time after the load current may be more than 1C. Now the length of time users load laptop have also become targets regardless of the manufacturers were forced to charge current set so high, so the first step is to reduce the current load.

Lithium-ion batteries is very precious, good circuit load control is required. With this method of pricing can reduce the load current to prolong battery life while using the notebook’s original charging circuit controls the charge current to achieve them is also relatively simple, just buy a sheet of power (that is, food in a sort of book, it is better to buy two, followed by the methods referred to another use, should be of good quality), and resistance can be, and note heads resistance should be greater, after all the above, there are about 2W of power Otherwise, it would be more resistant to heat, the best use of a constant resistance over me, this resistance wire resistance and temperature independent basis. However, the shortcomings of this approach is also very clear is that, while not charging the work with the laptop lighter load current problem is solved, and now pay problems. In fact, it is difficult, after all, the laptops are used at work, the discharge current varies with the serviceability, the method mentioned here is the limited capacity of the VGP-BPS2C battery is designed specifically for the restore operation.

To start the machine, within the parameters of power management will never go into standby mode (standby) and hibernation (hibernation), others are made more energy saving modes, including including processor speed, turn off hard disks, turn off the screen, so also in TP management process of closing some unused material, such as sound cards and so on, then open the status window battery display, and allowed to run in the foreground. Close other programs, including screen saver and other regular programs running. Do not use the machine, do not close the lid, let the battery discharge is completed (not to discharge the minimum value is set to 0 can be set at 3%). Display and hard drive after closing the discharge current of approximately 0.5 A (IBM R31 can be performed on a minimum discharge current), the battery discharge to a minimum value determined after the machine s ‘automatically stops.

The discharge lasted about 4 hours, depending on the capacity of your battery may be different in different.

Finally stressed that the above method is not dead, and in particular, discharge, or 10 times what can be done once and elsewhere also

Battery does? Charge is best done with a low load current, of course, if the need to use the sony VGP-BPS2A battery directly to the power plug inserted into a laptop on it.
