ER26500 Size “C” CMOS Battery, P/N: 51192060-100

The xPM power systems are designed to provide battery backup to all the CMOS memory. The CMOS battery backup prevents the loss of the data base during a power outage after the battery backup has been depleted or if no battery backup module is present. There are two different power system chassis out in the field with CMOS batteries. The older style power system introduced with PM/APM requires three specific “AA” size batteries. For the current back panel introduced for HPM the CMOS memory requires three specific “C” size batteries. The size “C” batteries are required if the full 50 hours of CMOS memory backup is desired for HPM due to the larger memory available in HPM.
