Should You Disconnect Your Car Battery While Charging?

The Short Answer

It’s always a good idea to disconnect your car battery before charging it. This is because charging a battery produces gas, and if the battery is connected to the car, the gas can ignite and cause an explosion.

Furthermore, if there is any damage to the battery, charging it while it’s connected to the car can fry your car’s electrical system. It’s much safer to remove the battery and charge it in a well-ventilated area away from the car.
