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 should be properly ventilated. Do not lay tester on battery. Do not test frozen batteries. 1. Turn off engine, accessories and battery test equipment. 2. Connect clamps to battery posts (bla

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 high or low average temperature. See chart below. Example: if rated capacity is 800 CCA and internal temperature is approximately 35° F, assume test capacity to be 560 CCA. (800 CCA x 70% (at

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 basic load test (push and release red load test button). Note the exact voltage with the load test on. If voltage continues to fall after 8 seconds, this test will not be available. 2. Apply t

M.A.C. TEST (A QUICK CHECK FOR APPOXIMATE STATE OF CHARGE) M.A.C. = Minutes After Checking (below 30° F, allow two minutes) Note: If load test is unsatisfactory, refer to the battery analysis chart on page 2. 1. If load test is O.K., leave tester connected and observe meter. If pointer moves to the right of the green area (white charging area) in less than one minute after load test, it indicates a reasonable state of charge. 2. If meter reads within or below the MAC area AFTER one m

CHARGING SYSTEM TEST (Alternator / Generator / Voltage Regulator) Before running the charging system test, inspect vehicles charging system for low voltage or over-voltage condition, otherwise you could damage the battery. Alternator/Generator should be at normal operating temperature before running test. 1. Follow steps 1-3 for battery load test. 2. Turn off all electrical accessories and run vehicle at 1500 R.P.M. 3. DO NOT PUSH LOAD SWITCH 4. Note meter reading with all el
