Can i change in battery myself - Cars & Trucks

Number 1 tip when changing batteries is to maintain 12 volts to the battery connectors during the change over. You can do this with a battery minder, a battery charger, jump leads or just a couple of lengths of wire.

You need to reset the security system immobilizer.
