Basement Watchdog Maintenance Free AGM Standby Battery

The Basement Watchdog Maintenance Free AGM Standby Battery is designed to be completely sealed, offering unparalleled reliability and convenience for your battery backup sump pump system. This eliminates the need for adding battery fluid or distilled water. It is crafted to seamlessly integrate with a wide range of Basement Watchdog systems, including the Basement Watchdog Emergency (BWE), Combination (DFK961, CITE-33), Special+ (BWSP+), Big Dog+ (BWD12-120C+), and the Big Combination sump pump system (BW4000, CITS-50) equipped with the Special + backup controller. Compatibility is ensured by the '+' sign on the upper left-hand corner of the BWSP+ and BWD12-120C+ control panel. Engineered for endurance, it is capable of powering various Basement Watchdog sump pump systems intermittently across several days. For extended reliability, connecting 2 batteries to amplify the run time is possible for BWSP+, BWD12-120C+, CITS-50, and BW4000 with Special + backup controller, using parallel battery cables.
