Battery capacity
correctly after double check. Incorrect settings affect the charging
power. When battery strings are shared, the battery capacity of each UPS is the total
capacity of battery strings. When no battery string is shared, the battery capacity of each
UPS is the capacity of battery strings connected to the single UPS. If you are not sure how
to determine the battery capacity, contact Huawei technical support.
High or low charging power tends to shorten the battery lifespan, or even damages
batteries.
Number of cells
indicates the number of 2 V DC batteries in a battery string connected to
the UPS. (If 12 V batteries are configured, the number of cells equals to the number of
batteries multiplied by 6. If 2 V batteries are configured, the number of cells equals to the
number of batteries.) This parameter affects the charge voltage and discharge time.
Incorrect setting will cause a high or low charge voltage, which greatly shortens the
battery lifespan. In addition, the UPS may shut down in advance during discharging,
which may result in data backup failure.
