Nominal Battery Life

The nominal battery life at 50ºC is 12 months or 60 charge/discharge cycles. Battery life is negatively affected by
higher temperatures, and can be significantly improved by operating closer to room temperature (25ºC). When
deciding where to mount the battery, consider how the mounting location will affect the battery temperature. For
most industrial installations, mounting the battery below the PLC rack will result in a temperature closer to 25ºC
and will help improve battery life. Do not operate the battery at less than 0ºC or greater than 50ºC.
The battery will continue to operate after 12 months or 60 charge/discharge cycles, however the battery capacity
will decline and the times listed in the Battery Compatibility and Memory Retention Time in Days at 20°C chart will no
longer be valid.

Battery Mounting

With power removed from the equipment, drill four #29 (0.136") holes in the panel mounting surface, and tap for
#8-32 threads, according to the hole pattern shown in the following figure. Use care to keep metal chips from
falling into other equipment. Securely attach the rechargeable battery module to the panel mounting surface using
four #8-32 x ½" flat head machine screws.
