BASIC BATTERY LOAD TEST (Conventional & Maintenance Free types) This test evaluates the battery’s ability to crank an engine. The tester draws current from the battery while measuring its voltage level. Batteries generate explosive gasses, which can be ignited by a spark or open flame. Work area...

COLD TEMPERATURE EFFECTS Because of the battery’s chemical nature, it will test lower when cold than when warm. For most accurate results, this effect should be compensated for when the battery’s internal temperature is below 40  ° F. Assume internal battery’s internal temperature to be the day’s h...

STARTER MOTOR TEST This test identifies excessive starter current draw, which makes starting difficult and shortens battery life. Perform battery load test and proceed only if the battery tests good. Engine should be at normal operating temperature. 1. Connect clamps to battery posts and run the bas...
