Sure, if the alternator voltage regulator is defective it can overcharge the battery.
Overcharge, often due to a shorted cell.
Yes, but make sure you do not overcharge the battery.
Shopkeepers should not overcharge.You can't overcharge a battery.
Usually, overcharge, sometimes overdischarge. Check the alternator - the regulator is probably shorted.
your car is usually has a 12 volt battery, on the charger set it to 12 volt charge, the batter will tell you how long to charge it usually 4 hours, do not overcharge, will damage battery :)
You can but you can alos easily overcharge the battery.
Defective voltage regulator.
Not necessarily. There could be different components at fault when your laptop fails to charge properly - the power supply (power brick), the charging circuitry inside the laptop for the battery, and/or the battery itself (which in itself also has a circuit for diagnosis, telemetry [battery level, battery health], and overcharge protection).
No, it will overcharge the 6 volt battery.
Do you have an Xbox controller that can be plugged into the front of the console to charge the battery? This does not work for AA batteries, but only for the official batteries that only work in the controllers. If you are using this recharging system, make sure that you do not overcharge the battery. You need to disconnect it when it is done charging, as indicated by the lights. Leaving it on for too long is very bad for the battery itself, causing it to wear out or even overheat, so overcharging can shorten the battery's total lifespan.
