Can you overcharge a battery at 2 amps?
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.
