The DSC Alexor XCELPLUS Extended Life model is a high capacity battery backup for the latest range of Alexor series wireless alarm siren bell boxes. The Extended Life model is recommended for anyone that requires more hours of backup from their siren bell box and doesn't want to replace the battery for the next 5-6 years.

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

The DSC Alexor XCELPLUS Extended Life and Standard model battery are compatible with the WT4911B siren bell box only. The XCELPLUS Extended Life is the highest capacity battery available on the market for the Alexor bell boxes and unlike budget consumer batteries, it's produced using the highest capacity 20,000mAh lithium thionyl chloride (Li-SOCl2) battery.
