For 1990-2009 cars

The battery will not last indefinitely. With proper care, the battery will provide many years of service.

• | When the battery tests well, but fails to perform satisfactorily, check for the following conditions:

- | A vehicle accessory is left on overnight.

- | Long periods of slow driving or short trips that do not allow sufficient time to recharge the battery.

- | The electrical load on the vehicle is greater than the generator output. This can happen when aftermarket equipment is added.

• | Check the charging system for the following conditions:

- | Poor ground connections

- | Electrical shorts

- | A slipping drive belt

- | A faulty generator

• | Check for the following that results from a poorly maintained battery:

- | Corrosion on the battery terminals

- | Loose battery cable clamps

- | Operating the vehicle with a loose battery hold down

• | Check the exterior for damage to the battery case.
