Is it better to charge a battery at 2 amps or 10 amps?
Slow charging using 10 amp chargers or less is generally accepted to be better. This is because repeatedly fast-charging a car battery may lead to overcharging and will severely reduce its performance. The short answer: 10 amp chargers are generally preferable than 2 amp chargers.
What happens if you leave a battery charger on too long?
A: If you leave the charger connected continuously, even at a mere 2 amps, the battery eventually will die.
