VE Commodore Battery
The battery in the VE Commodore is located in the passenger side rear quarter and, as with all cars, you need to make sure the battery has enough charge in it to start your car. When not driving your car, make sure your headlights are off and your accessories are off as they will drain your battery over an extended period of time.
It has been reported by some that in the early VEs the car will drain the battery over the course of a day, and in some extreme cases over about an hour. If this is a problem that occurs for you, take your car in for a service and detail the problem and they should be able to fix it for you.
