Subject: DELCO FREEDOM BATTERY DIAGNOSIS AND CHARGING PROCEDURE


Model and Year: ALL MODELS WITH DELCO FREEDOM BATTERIES
TO: ALL CHEVROLET DEALERS


The following information will explain the characteristics of the Delco Freedom battery and the effects of parasitic loads (small constant drains on the battery due to standard and optional equipment). The effect of outside temperatures on battery power and proper battery charging and testing procedures are also discussed.

Notice: All batteries generate hydrogen gas which is extremely flammable. If ignited by a spark or flame, the gas may explode violently, causing spraying of acid, fragmentation of the battery and possible severe personal injuries. Wear approved eye protection. Battery fluid is corrosive acid, flush any contacted area with water immediately and thoroughly.

Most deeply discharged batteries CAN be recharged if proper procedures are followed.

Examples of conditions causing low charged or discharged batteries are:

1. Extended storage of vehicles.
2. Batteries being less than adequately charged when received.
3. Extended cranking periods due to plug fouling.
4. Driver habits.
5. Incorrect interpretation of the charge indicator.
6. Inability to determine the correct ampere-hour charging rate for a discharged battery.
7. Burned out charge/gen light bulb causing "No Charge" condition.
8. Charging system problems.
9. Continuous current draw on the battery thru increased parasitic drain.
