Lifetime of Backup Battery
The life of the backup battery will eventually expire and therefore it is important to re-
place it with a new battery periodically. The battery lifetime will differ depending on the
operating conditions (i.e., ambient temperature) and the type of expansion memory
unit. Refer to the table below for a guide as to when to replace the battery.
