AGM Battery Testing Procedure
-
Test battery using the battery tester PU-50296.
-
If the tester indicates a test result other than “Good Battery,” follow the steps below before replacing the battery:
-
Connect battery to the recommended battery charger. If charging sequence begins as normal, fully charge battery and proceed to step 3.
The time listed on the PU-50296 battery tester printout is an estimate. The recommended automatic charger will indicate when the battery is fully charged on its display.
-
If charging sequence does not initialize, refer to AGM Battery Charging Recommendations – Deeply Discharged (below 3 volts) to attempt to restore the deeply discharged battery. If charging sequence will not finish as intended, the battery needs to be replaced.
-
-
Re-test battery. If the test results show that battery failed, proceed with battery replacement.
