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.
