Apparently so. I left my cheap Sylvania MP3 device charging for an hour or so, when it had only 2 bars of power left on the gauge. After continued use throughout the week, the device repeatedly died quickly from 3 bars (full power) to 2 bars within 3 minutes of playing music (with headphones).

Overcharge, often due to a shorted cell.
Defective voltage regulator.
No. The computer and charger are "intelligent" and will prevent overcharging.
Yes, but make sure you do not overcharge the battery.
Sure, if the alternator voltage regulator is defective it can overcharge the battery.
No, a 12 volt charger will overcharge a 8 volt battery and destroy it.
Yes, as long as you do not overcharge it.
When you overcharge the battery on your laptop computer, it can wear out more quickly. As soon as the computer says that you are using reserve battery power, you need to plug it in. When the charging indicator light turns from orange to green, though, you have to unplug it. This means that the battery is full. You do not want to keep sending electricity into it after it is full. Unplugging it will extend its life.
