Features:
XCELPLUS are the only producer of Visonic batteries which include a PTC resettable fuse, used to protect against overcurrent faults or reverse polarity insertion. All batteries can leak acid when they're depleted for long periods if gone un-checked. 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.
