Context
● The following method applies only to the scenario where the UPS2000-H-10
kVA is used to recharge a battery pack.

are correctly and securely connected.
● When recharging a battery pack, assign personnel to monitor the entire
recharge process and perform inspections periodically. If any of the following
exceptions is detected, stop charging immediately.

For example, if there is one battery pack, the battery pack capacity is 9 Ah, and the
charge current limit coefficient is 0.15C, the charge current is calculated as follows:
Charge current = 1 (Number of battery packs) x 9 (Battery capacity) x 0.15 (Charge
current limit coefficient) = 1.35 A. The charge current of a battery pack is associated
with the battery capacity. A maximum of four battery packs can be connected in
parallel. Table 3-2 lists the charging time.
The time requirements for using the UPS to recharge battery packs are as
follows.
