Battery Hydrometer PN 2870836 Load Test A battery may indicate full charge condition in the OCV test and the specific gravity
test, but still not have the storage capacity necessary to properly function in the electrical systemFor this reason battery
capacity or load test should be conducted whenever poor battery performance is encounteredNOTE: This test cannot be performed
with an engine or starting system that is not working properly1Attach multitester to the batteryThe reading should be 12.4
DCV or greater2Engage electric starter and view registered battery voltage while cranking engineContinue the test for 15
