    I heard that was bad. Are you only suppose to plug it in when the batter gets low and then disconnect it? I left my battery plugged in for around 6 hours yesterday...

    The battery and charger in the laptop is pretty advanced and trickle charges the battery when its full. So no, overcharging is not a problem like it once was, infact lithium batteries like to stay charged...

    However people who have the laptops on desks all day prefer to charge the battery and then remove it and run the laptop on power. I dont know how valid this is but I suspect it would only be helpful if you left your laptop on charge all day, almost every day.

    However the person who I bought my mac off did that and the battery was in perfect shape :dunno:

    Yes, but that was also on many of the older laptop batteries. I would say it's a pretty null issue anymore. :dunno:

    I'm sure it's a lot worse for the computer to knock the power cable out while the battery is out and the computer is on than to run the computer with the battery in and the cable connected.

    u r supposed to leave ur laptop unplug from time to time to maintain the battery life. leaving it plug on at all tmes is definitely bad for ur laptop.

    that's only kind of true, unfortunately. The thing about lithium batteries is that they also lose their permanent capacity fastest when they're kept at full charge under high temperatures, just like you find in laptops. Leaving a fully charged Li battery in a hot environment will make it lose its full capacity pretty quickly... so if it's not a terrible inconvenience, it's a good idea to disconnect the battery when using your laptop at a desk for extended periods.

    wikipedia actually has a great write-up on Li batteries and why/how they're different from other ones. They also lose permanent charge just sitting on the shelf, doing nothing, for example... so buying a second battery you never use is actually a bad idea if it's lithium.

    no problem :cool: lots of people assume that Li-ion batteries are a silver bullet, but after I read that article I learned a lot :o they're still good batteries, you just have to know how to treat them.
