Battery reconditioning

[Speelgoedmannetje]

I've heard that putting the battery in the freezer will also do some good to batteries.

Hm I didn't have a lithium-ion I think.
Tis an old laptop I tried it with, in my case I had no succes, it made no difference.

AFAIK it's SUPPOSED to become completely empty, and the very reason laptop batteries often get bad is because of recharging when not empty.

Could be, but personally I always prefer hardware doing these kinds of jobs.

Battery management ICs generally use an analogue sense circuit to judge the battery's state. The sensory elements are often not very precise, and may not really indicate the true state of the battery. I worked on a battery management design a while back, and all the ICs required individual external trimming, and most would not perform reliably on batteries of all different conditions. Unfortunately, cheap analogue IC elements are subject to this kind of variation.

Are you saying that the battery might not actually be as bad as the computer thinks? Or that it's not actually fully charging it? Or both? Or neither? :-)

More often than not I guess... analog to digital (or vice versa) is very fragile stuff.
