Replacement.
Directions for replacement.
APC recommends that a whole battery module (four batteries) is replaced
at the same time to ensure optimal runtime (see Example 1). However, it is only necessary to replace two
batteries at the same time according to Example 2 and 3 in the below tables.
Caution
Batteries must be replaced by trained personnel only (see the section General safety
prior to Battery Module replacement).
