How to use the most reasonable computer battery, to avoid bottle or damage to the battery.

You have been using a laptop but do not know how to use the battery in the best way. The following article will help you answer that question in the most concise and accurate way.

Many articles published and advised computer users as “If you regularly sit in one place, you can fully charge the battery and then remove the battery and just use the charger, expert advice to extend the life of the laptop battery. Unfortunately, this advice can make the laptop “die suddenly”.

The view of putting the battery away will be very harmful because just once unlucky, due to the sudden drop in the power supply or the short circuit of the charger (adapter) used continuously for a long time, the circuit boards and chips of the machine will “Bear” risks with very high fire risks. The risk is data loss, file error, system software error when the battery is not installed. Because in a power failure situation, the battery functions as an instantaneous UPS (UPS on-line).

And the point of “continuous charging while in use will make the battery bottle or quickly damage” is also inaccurate. Today computers are all designed switches, automatically select the right power supply, stability, and new generation batteries. This means that these machines have the ability to use the power directly from the charger, without the need to insert the battery and if the battery is installed, it also automatically selects the power supply from the charger when the current is stable.

So the method of using the most correct is to use normal batteries: Fully charged, use the charger when working from home, use the battery when traveling. Note: only remove the battery when the device is completely turned off and the charger is not plugged in. When charging the battery, should plug the power connector into the power outlet first, plug the charger into the following machine. Finally, if you find that the battery depletes too quickly, abnormally hot, you need to think about cleaning the electrical contacts on the battery.

How to use Laptop Batteries?

You should not put your laptop on a mattress bed or use a pillow instead of the laptop’s desk because they will hide the heat outlet under the lap.
Plastic should not be glued to the device, as the case is a useful heat release ingredient.
When finished, turn off the device, so wait a few minutes to put the device in the bag or backpack because they keep the heat quite well, the heat in Lap that has not been fully released will be harmful to the machine.
Limit use of laptop until battery exhaustion because Li-ion battery used for laptop has no memory effect, so battery bottle condition occurs. The manufacturers themselves have limited this when only for the laptop to operate when the battery is> 5–10% below that level, the machine will automatically turn off.
When using the battery, use it until it has 10–20% charge again, because if you only use a few% and have recharged many times, the cell number of the unused battery will also bottle itself.
If you plug in regularly, also try to charge and discharge periodically every 1–2 weeks. (almost used up and fully charged) It is advisable to clean the battery contact circuit, to avoid poor contact and damage to the battery.
Do not remove the battery and use the power source directly because the direct power source is not stable, when the problem occurs, it will affect the work you are doing and the laptop (power failure, main …). Do not use to 0% capacity often, set your device to go into “hibernate” mode when the battery is about 5% -10% of its capacity. Recalibrate the “battery meter” (re-calibrate) every 3 months using the battery until it turns itself off due to the lack of battery, and then fully charge it again before continuing to use it normally.

When the battery is in battery condition or the battery management board is not getting the correct capacity (like a clock running early / late) you can use a trick (re-calibrate) that will help you improve this. Plug in fully charge the battery, then unplug it and use it normally until it is almost exhausted, when it is about 7–10%, then reboot the device and enter BIOS mode, leave the device to 0% and the device automatically off because the battery is exhausted. Leave the battery in that 0% state for about 6–8 hours, then plug it in again and use it normally.
