(Note 4)

Note 1 Values outside these ranges indicate action is necessary to restore the parameter

to within the specified values.

Note 2 Battery cleaning should be done with baking soda and water with clear water rinse--

no other cleaning materials shall be used.

Note 3 All manufacturer's safety precautions should be observed when working on

batteries.

Note 4 Not required where battery is for engine generator only and not other loads. The

periodic monthly start of the engine generator is a load test. Load tests should be

done in as-found condition.

Note 5 Battery capacity (performance discharge) test is used as a battery age indicator.

Initially, battery should be fully charged, temperature near 25 C, and terminals

clean. See IEEE Std 450 for times the battery capacity test should be performed.
