Conditioning Laptop Batteries?

Question

Ive heard it several ways about preserving battery life, some say drain it completely, recharge full, and repeat, some say never keep it too low or too high when it reaches 40% charge it to about 90 and stop. So my question is, i have a lithium-ion battery for my laptop, what is the CORRECT thing to do with it to preserve its life? Real answers please no guesses i can make things up on my own too.

Answer 1

The first answer was absolutely positively correct, if you had a Nickel-Cadmium battery. Do what he said with your lithium-ion battery and you will be lucky if you can ever use it again. Lithium-ions are the 40% you have heard about, never ever let them drain below 40%. It also extends the battery life somewhat if you keep it away from heat when at all possible. There are several things you can do to help battery life, I will give you a link to a good article to read, but the most important for Lithium-Ion is the 40% rule.

Answer 3

ok your first roumor is most correct.. what you want to do is compleatly drain your battery.... use it until it stops working.. leave it that way for 4 hours without plugging it in.... just let it sit there dead.

then recharge it fully and leave it plugged in completely charged over night.

repeat this every month or every other month this will increase your battery capacity and life.
