For example, if two battery packs are connected in parallel in the positive and
negative battery strings respectively, the battery pack capacity is 9 Ah, and the charge
current coefficient is 0.1, the charge current is calculated as follows: Charge current =
2 (Number of battery packs) x 9 (Battery capacity) x 0.1 (Charge current coefficient) =
1.8 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 in the positive or
negative battery string.
The time requirements for using the UPS to recharge battery packs are as
follows.
