This short video gives an excellent tutorial on how to fix a dud laptop battery. The footage assumes you have a battery which contains standard Lithium cells which can be easily replaced with a minimum of soldering, so if your machine doesn’t, you’re probably best advised to go out and just buy a new battery if you can afford it.
It never occurred to me that laptop batteries would contain easily replaceable cells (duh) so this is really interesting. Of course you’ll need to be proficient enough to use a soldering iron and MOST IMPORTANT – DO NOT do this if you are in any way uncertain as to how to to wire together circuits and stuff. Lithium battery cells have a tendency to explode if mistreated, overheated etc, so IF IN DOUBT – DON’T DO IT!
There, have I put the warning strong enough for you?
Dead laptop battery? Don’t buy a new one…hack the old one! I’ll show you how!
