Battery Load Test
Connect battery tester according to tool manufacturer's instructions. Load test battery at approximately one-half cold-cranking amperage rating for 15 seconds while observing battery voltage. Compare readings to BATTERY LOAD TEST SPECIFICATIONS table. If voltage readings are within specification, battery is okay. If voltage readings are not within specification, charge battery and retest. If loaded battery voltage is still not within specification after charging, replace battery.
