battery question

#1 Post by nontechy » Sat May 20, 2006 11:14 am

I just got my x60 and let me say, it's awesome.

I have a stupid question about charging the battery. If the battery is at 100%, do I need to unplug it from the charger? Would I "kill" the battery if I recharge it when it's at 70% (arbitrary number)?

1) You can leave the machine plugged in when the battery is at 100%. There will be no problem.

2) You can start recharging the battery whenever you want. It will not cause a problem. [incorrect info about deep cycling batteries removed]

Congratulations on your new X60! :D

I run my battery down to around 15% about once a month. Have been doing this for years and as a result I have experienced very long battery life, both in terms of how long it runs on the battery after charging and also the total lifetime of the battery. Before I started this routine I would get from 10-12months battery life. Now using the described routine I get 16-18 months battery life.

Enjoy your new ThinkPad

Absolutely NEVER "deep charge" a lithium battery. That will do far more harm than good. Also, only let the battery run down to a low level if you are going to store it. Otherwise, you will only reduce overall longevity. Lithium batteries like to be kept at a high level of charge when in use.

Oops, you're absolutely right. Ignore what I said above about deep cycling.

Is it OK if I "deep six" my old dead batteries? :)
