What happens if you leave a car battery charger on too long?
A: If you leave the charger connected continuously, even at a mere 2 amps, the battery eventually will die. Overcharging a battery causes excessive gassing — the electrolyte gets hot and both hydrogen and oxygen gas are generated. … On sealed batteries, the buildup of gases could cause the battery to burst.

Can a completely dead car battery be recharged?
