3. Check the battery surface
temperature.
4. Keep deformed and
bulged faulty batteries
still for 30 minutes and
then check and record
open-circuit voltage of
the faulty battery.

1. Check whether the
equalized charging
voltage and float
charging voltage of a
battery is normal.
2. If the charging voltage of
a battery exceeds the
specifications
requirement, perform a
complete forcible
equalized charging for
the battery, and check
again whether the
voltage is normal.
