Load Test
WARNING:
Dispose of electrolyte (sulfuric acid/water mixture) properly. Waste electrolyte must only be disposed of in appropriate waste disposal sites.
WARNING:
DO NOT load test batteries which are gassing. There is a risk of explosion.
NOTE:
On vehicles made after August 1998, it is not necessary to remove battery.
NOTE:
Manufacturer recommends performing electrolyte specific gravity test, in order to determine battery overall condition.
Remove battery from vehicle. Connect tester cable clamps to battery terminal. Ensure clamps have a good contact with battery terminals. Connect battery tester according to tool manufacturer's instructions. Load test battery at approximately one-half cold-cranking amperage rating for 5 seconds while observing battery voltage. If voltage reading is 9.6 volts or more, battery is okay. If voltage reading is less than 9.6 volts, charge battery and retest. If loaded battery voltage is still less than 9.6 volts after charging battery, replace battery.
