How to extend the life of your laptop battery



Batteries don't last forever. Like everything except diamonds and viral tweets, they eventually wear out. But with proper care, a laptop battery can still carry a sufficient charge until you're ready to move on to a better laptop.

But it's a tradeoff. Taking the best care of your laptop battery just may be more of a hassle than it's worth.



So let me start with a less effective, but more practical approach:

When you're at home, running the laptop on AC power, and you believe that it will stay plugged in for a week or more, shut down the PC and remove the battery.

Then, when you need the battery, plug it back in. If it's been more than two months since you last used the battery, check it and charge it before taking it on the road.

Of course, you should never remove or insert a laptop battery while the laptop is running. Always shut it down first.

That's the practical approach. Here's the extreme care method:

For the absolute best results, never charge it past 80 percent or let it drop below 20 percent. When you're working on AC power, keep an eye on the battery's charging.  When it hits or passes 80 percent, shut down your computer, remove the battery, then reboot. When it's time to take the laptop on the road, shut it down again and reinsert the battery.

And when you're using the laptop on battery power, shut it down before the battery drops below 20 percent, and don't start it up again until you have AC power.

Laptop battery using instruction

Laptop battery using instruction


    * Most of the new laptop battery at the factory are set to sleep mode, the first boot with only about 5% of the electricity. You should not use an external power supply at this time, let the battery exhausted, until shutdown, then switch on the external ac adapter and the first charge had better over 15 hours. After fully charged, you should charge after the exhaustion of batter, the time of the second and third charge should be more than 12 hours, in order to activate laptop battery and lay a good foundation for future use.

    * Notebook's battery life is measured in terms of the number of charging and discharging. Do not enable the laptop battery unless it is necessary, if you don't use the battery for a long time, you should charge it to about half full and place in a cool place to keep. If you enable the battery, you should run out of power after the charging, and do not plug in the AC power before exhausted. When the laptop batteries fully charged, you should disconnect the AC input because overcharge will make the battery overheat and that will shorten the battery life.
    * Generally speaking, nowadays the laptop are with intelligent battery protection, the laptop batteries will not be damaged due to normal operation, but still may damaged for the life-span of battery or other special reasons.

    * Lithium-ion battery should fast charge in constant current and then switch to slow charge in constant voltage when the voltage reaches a certain value. Usually the laptop doesn't have a strictly constant-current charge monitoring device. Charge current will turn small when system load large and vice versa, the current is decided by the AC power adapter power margin, it is obviously.

    * Discharge in a current as small as possible, the action is to slow down the CPU, stop the hard disk, adjust the screen to the most dark, and then do not run any programs until the laptop automatically shut down. The reason to emphasize the small current discharging is to prevent the laptop premature detect the laptop battery voltage shortage.
