- Measure battery voltage. If 12.4 volts or more exists, go to step 3. If less than 12.4 volts exist, go to next step.
- Quick charge for 30 minutes and recheck voltage. If 12.4 volts or more exists, go to next step. If less than 12.4 volts exists, replace battery.
- Apply load test to battery using a battery load tester and record battery voltage after 15 seconds. See BATTERY LOAD TEST SPECIFICATIONS table. See LOAD TEST MINIMUM VOLTAGE . If voltage is within specification, battery is okay at this time. If voltage is not within specification, replace battery.
