Backup battery for CP2E N/S CPU units; supports clock retention and cannot be mounted on E-type CPUs.
Optional backup battery for OMRON CP2E N- and S-type CPU units. Official OMRON documentation states it is mounted in an N/S-type CPU Unit and is required when using the clock function; it cannot be mounted to E-type CPU units. Distributor and manufacturer pages identify it as a controller accessory battery for CP2E.

Used in CP2E N/S CPU units where exact timekeeping must survive power loss for traceability and event logging.
Prevents loss of clock-based timestamps after outages.
Supports systems that may be periodically de-energized while retaining the CPU clock in compatible controllers.
Maintains time-based control behavior through planned shutdowns.
Enables CPU units to preserve calendar time for scheduled operations, alarms, and sequence records in compact automation systems.
Keeps schedule-driven logic and logs accurate after restart.
