The Visonic XCELPLUS Extended Life model is a high capacity battery backup for the PowerMaster series wireless alarm control panel. The Extended Life model is recommended for anyone that has a PowerMaster and requires more hours of backup from their control panel and doesn't want to replace the battery for the next 4-5 years.

The Visonic XCELPLUS Standard model are also suitable for the PowerMaster series alarm, but may only offer 3-4 hours backup in the event of a power cut, and require replacing within 2-3 years.

The Visonic XCELPLUS Extended Life and Standard model battery are compatible with all PowerMaster control panels. The XCELPLUS Extended Life is the highest capacity battery available on the market and unlike budget consumer batteries, it's produced using the highest quality industrial, nickel-metal hydride (NiMH) batteries.
We also supply small highly visible UV resistant white vinyl window stickers, suitable for placing on the inside face of any glass surface, visible from the outside. Two pieces of window sticker are available for purchase when ordering the + 2 Stickers option battery. These Visonic stickers can also be purchase separately through our shop on ebay with free postage.

Variations:
Depending on the requirements of your PowerMaster system, your installer may have installed 1 of 2 different specifications of backup battery. The most common is the UL Install 2300mA 6 cell pack, with the 1300mAh supplied in earlier models.

Visonic recommend the Extended Life UL Install battery. This is the only insurance approved battery offering 24hr backup

Features:
XCELPLUS are the only producer of Visonic batteries which include a PTC resettable fuse, used to protect against over-current faults or reverse polarity insertion. All batteries can leak acid when they're depleted for long periods if gone unchecked. PTC resettable fuses prevent further damage to the control panel from short-circuit faults caused by battery acid. As of 2014 all batteries sold by XCELPLUS now feature this vital protection.
