* Required Fields



The Siemens XCELPLUS Extended Life model is a high capacity battery backup for your outdoor siren bell box. The Extended Life model is recommended for anyone that requires more hours of backup from their siren and doesn't want to replace the battery for the next 4-5 years.

The Siemens XCELPLUS Standard model is also suitable for the latest PowerMax series alarms, but may only offer 2-3 year life depending on the frequency of use.

The XCELPLUS Extended Life and Standard model battery are compatible with the Siemens system bell boxes. The XCELPLUS Extended Life is the highest capacity battery available on the market for the MCS-720 bell box and unlike budget consumer batteries, it's produced using the highest capacity 20,000mAh lithium thionyl chloride (LiSOCl2) battery.
