Interpreting Test Readings
If the measured capacity of a battery is less than 80%
of the rated capacity, the battery should be re-tested
until the measured capacity is above 80% OR until it
ceases to increase from one test to the next.
If the measured capacity of a battery is less than 80%
after three or four test cycles, it should be removed
from service and disposed of in accordance with local
requirements.
Error Codes
There are two error codes that are displayed to
indicate that an error has occurred.
The code ER-1 is displayed if the battery under test
loses contact during the test. If this code is displayed,
the test should be repeated.
The code ER-2 is displayed if the battery under test is
out of the acceptable voltage range for charging. If
this code displays repeatedly, the battery may have a
bad cell. It should be removed from service and
disposed of in accordance with local requirements.
