Battery Maintenance
The RIM-600 Host includes an internal UPS that automatically switches to battery backup in the
event of an AC power failure. The battery in the RIM-600 Host is a 12V 2.9AH gel cell. This bat-
tery will keep the unit operating for approximately 3.5 hours when fully charged and under normal
operating conditions.
Service life
Over time and with periodic use, the battery will begin to lose its capacity, resulting in less overall
backup time. Under normal operating conditions, three or four years of dependable service life can
be expected or between 200 and 1000 charge/discharge cycles, depending on the average depth
of discharge. Eventually, battery replacement will be required to maintain a dependable level of
service.
