Battery Common Causes of Failure

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, inspect 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.
