hi, I use a laptop but I don't really need to use the battery right now. Is it better to store it compleatly charged, compleatly drained, or just a little charged?

I'd suggest running it till it's dead before storing so it doesn't slowly discharge itself while it's in storage. When you take it back out of storage it'll take a few charge/discharge cycles to get back to full capacity but it'll keep the battery usefull for a longer period of time.

 

 

 

A quick googling for "battery storage" gave quite a few usefull pages on the subject too. :wink:

Half-charge. Full empty and full charge are both bad for weak lithium batteries. But you shouldn't recharge it when you go back from half-charge, you need to empty then charge again.

 

 

 

Lithium batteries are a pain :\ i usually run them till they're junk, dispose properly then purchase a new one (well..purchase a new one first actually so it comes =-p)

yea I was thinking more along these lines, since when you buy the laptop there is a little battery power anyways.

 

 

 

Does anyone want to confirm this for me? I dont really want to junk an expensive battery.

er, I've left batteries idle for months at a time, charged, uncharged, you name it... never had any problems, and these are the batteries I've been using for 3 years now.

ok.. if its a lithium battery

 

 

 

charge it to 40%

 

 

 

when your batterys not being used it will slowly loose charge.. and once litium batteries get to a certain point they wont let themselves be recharged.

 

 

 

also put it in the freezer in a air tight baggie and then put it in the freezer

 

 

 

this slows down the dieing of the battery

 

(lithium battries die no matter what even if they are not used ever)
