
Battery capacity is set only after the dialog box is confirmed. An incorrect setting reduces
the charging power.

When a battery string is 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
battery capacity of the single UPS.

A high or low charging power may shorten the battery lifespan, or even damage batteries.
If the battery capacity cannot be confirmed, contact Huawei technical support.

Number of cells refers to the number of 2 V cells in a single battery string connected to
the UPS. For example, the number of cells must be a multiple of 12 (for example, 180 and
192). If 36 batteries (150 Ah, 12 V) are connected in series to form a battery string, and
two of such battery strings are connected in parallel and then to the UPS, set Number of
cells to 216 (36 x 6) and Battery capacity to 300 Ah (150 Ah + 150 Ah). If 192 batteries
(300 Ah, 2 V) are connected in series to form a battery string, and two of such battery
strings connected in parallel and then to the UPS, set Number of cells to 192 (192 x 1) and
Battery capacity to 600 Ah (300 Ah + 300 Ah). An incorrect setting will cause a high or
low charge voltage, which greatly shortens the battery lifespan. Moreover, the UPS may
shut down before the batteries are fully discharged, which may lead to a data backup fault.
Step 3 If no alarm is displayed on the Monitoring screen, skip this step; if an alarm is displayed,
clear the alarm.
