ISSUE: Some vehicles may not crank because of a low battery state of charge. A rapid recharge procedure has been developed for charging non-defective batteries needing only a recharge.

ACTION: If service is required, recharge the battery by using the following procedure.


BATTERY CHARGING PROCEDURE

This rapid recharge procedure may be used in recharging batteries that have been identified by a Load Test as non-defective and needing only a recharge. These can be...

^ In-service "no-start" battery failures (vehicle will not crank due to low battery state-of-charge)

^ Batteries discharged in vehicles due to "key-off" loads.


NOTE: PLEASE REFER TO THE BATTERY TESTING PROCEDURE ARTICLE IN THIS TSB FOR BATTERY LOAD TEST PROCEDURE.

Rapid charge the batteries by using either of the following methods...

^ Perform a 2 hour charge using either 20 ampere constant current (manual setting on charger).

^ Perform a 2 hour charge at constant potential (automatic setting on the charger).

NOTE: IF EXCESSIVE GASSING OR ACID SPEWING OCCURS DURING THE CHARGE, DISCONTINUE CHARGING. THE BATTERY HAS REACHED SERVICEABLE CHARGE. IF THE BATTERY WILL NOT ACCEPT AT LEAST 5 AMPERES AFTER 20 MINUTES OF CHARGING, REPLACE THE BATTERY.


WARNING: WEAR SAFETY GLASSES - BATTERY CHARGING CAN BE DANGEROUS. WHILE BEING CHARGED, THE BATTERY PRODUCES POTENTIALLY EXPLOSIVE MIXTURE OF HYDROGEN AND OXYGEN GASSES. KEEP SPARKS, FLAMES AND LIGHTED CIGARETTES AWAY FROM BATTERIES. REMEMBER, BATTERIES CONTAIN SULFURIC ACID. IN CASE OF ACID CONTACT WITH THE SKIN, EYES OR CLOTHING, FLUSH IMMEDIATELY WITH LARGE AMOUNTS OF WATER. GET MEDICAL ATTENTION.
