● Equalized charging
voltage: 14.1 V
± 0.1 V
● Float charging
voltage: 13.5 V

1. Check whether the
equalized charging
voltage and float
charging voltage of a
battery are 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.
3. If the fault persists,
contact Huawei
