Load Test
WARNING:
Observe accident prevention procedures. Wear protective clothing, such as goggles and leather gloves.
NOTE:
If using VAS (1979) or VAS (5033), it is not necessary to remove battery from vehicle, or disconnect battery terminals.
Turn ignition to OFF position. Following tester manufacturer instructions, connect tester cable clamps to battery terminal. Ensure clamps make good contact with battery terminals. Load test battery at approximately one-half cold-cranking amperage rating for 15 seconds while observing battery voltage. If voltage reading is 9.5 volts or more, battery is okay. If voltage reading is less than 9.5 volts, charge battery and retest. If loaded battery voltage is still less than 9.5 volts after charging battery, replace battery.
