Load Test
WARNING:
Dispose of electrolyte (sulfuric acid/water mixture) properly. Waste electrolyte must only be disposed of in appropriate waste disposal sites. Refer to local regulations pertaining to electrolyte disposal.
CAUTION:
Battery cell caps must be bolted in tightly when charging, measuring voltage or performing load tests.
NOTE:
Manufacturer recommends performing electrolyte specific gravity test, in order to determine battery overall condition. For specific gravity values, see SPECIFIC GRAVITY SPECIFICATIONS table.
NOTE:
On vehicles from 1997-99, it is not necessary to remove battery from vehicle, or disconnect battery terminals. On vehicles from 2000 and on, it is necessary to remove battery for load test.
Connect battery tester cable clamps to battery terminal. Ensure clamps make 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 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.
