First you mention AA non-rechargable batteries being charged and we tell you it dangerous.
Now you're asking if charging a laptop battery is dangerous and we're telling you it is not.
The rest of your posts are hard to understand, be more specific.
Yeah, I'm still trying to figure out how we got from ni-mh to alkaline AA batteries to li-ion laptop batteries.
Computer12, I haven't taken my laptop battery out of the laptop in over 3 years. Never had a problem with overcharging, explosions, or anything else. Just the fact that it ways a bit more with the battery in. Also, don't toy with dangerous things when you don't understand them. That's how people go blind, disfigure themselves, cause sterility, hurt their children, and wind up a freak show in some travelling circus.
Do not try to recharge non-rechargeable batteries. Do not put batteries of one type into a charger of another type, even if they are rechargeable (ex. ni-cd in ni-mh charger). And for the love of God, don't put a 9v battery on the tip of your tongue. Not only does it do nothing, it leaves a nasty taste in your mouth.
