Battery Replacement

Battery Replacement

Batteries determined to be detective through testing procedures should be replaced using the following guidelines.

- Reconfirm battery is actually detective and it does not need charging.
- Insure that ignition switch is in "Off" position and engine is not running.
- Disconnect negative battery terminal first.
- Place negative battery cable in a position so that it can not come in contact with battery during removal process.
- Reinstall battery hold down clamp.
- Install positive cable first.
- Recheck output of vehicle generator and balance of electrical system for other problems.
- Provide clear and concise description of the defect including cell readings, load test results and any other pertinent information which led to the battery replacement.
- Tag battery with VIN and repair order number.

Battery Failures

An analysis of batteries replaced under warranty shows that many claims could have been avoided had the batteries been maintained in a full state of charge.

Batteries must be maintained at all times when vehicles are at a retailer whether they are new cars, used cars, in storage (back lot), on display, or customer cars in for maintenance or repairs.

Batteries replaced due to lack of maintenance will not be covered by warranty.

Most Common Causes of Premature Battery Failures
- Failure to maintain proper state of charge.
- Loss of electrolyte due to overcharging or excessive heat.
- Deep discharging (Leaving lights on or other parasitic draws).
- Undercharging of battery.
- Vibration (Loose battery hold down clamp).
- Using tap water (instead of distilled water).
- Corrosion.
- Freezing.

Workshop Hints

Safety Tips
- Proper Clothing:
- Always wear a face shield or safety goggles.
- Plastic gloves can prevent acid burns to hands.

- Neutralizing Electrolyte:
Any leakage or spillage of battery electrolyte should be neutralized as soon as possible to prevent damage to paint, body or trunk linings. Depending on the amount of spillage dilute some baking soda in water and apply to areas of the car that have been exposed to the battery electrolyte. The neutralizing action will create some foaming in the area where the chemical action takes place. Flush with ample amounts of water once the chemical reaction has subsided.

General Battery Hints
- Add only distilled water NEVER TOP OFF WITH ACID.
- Keep electrolyte level above plate separators.
- Keep battery top clean and dry.
- Keep open flame and metal objects away from battery top and terminals.
- Keep vent caps tightly in place (if applicable). Use proper charging equipment.
