79 Chevy Chevette, Maintenance Free?
Q: I need some information concerning no-maintenance automotive batteries. I have always been told they cannot be recharged if they go down and that they must be replaced. I bought a new Delco maintenance free battery in April for my '79 Chevy Chevette. I've had trouble with starting and stalling ever since the battery was installed. On two different visits to the garage recently, I was told my battery was down and needed recharging. Why is this new battery doing this when I have driven less than 1000 miles? Could it be defective?

Due to unfortunate circumstances I cannot use the car this winter. Will it be all right to leave it in the car or would it be damaged by the cold weather?

A: No, it's not necessary to replace a battery when it gets low in charge. And there's no problem with recharging a maintenance free battery. As for the replacement battery being responsible for creating the stalling problem, not likely. More likely, there are maintenance issues, other than the battery, that need to be addressed. After all, the age of the vehicle is a factor.

Driving a vehicle less than 1000 miles a year? That, in itself, doesn't provide the necessary electrical activity (recharging by the vehicle's alternator) to properly maintain a battery's state of charge.

If your Chevette is going to be parked for an extended period of time the battery should be disconnected or removed and stored from the winter elements.
