The Basement Watchdog Maintenance Free AGM Battery is completely sealed making it the perfect choice for years of reliable service for your battery backup sump pump system without having to add battery fluid or distilled water. This battery is compatible with most Basement Watchdog systems including the Basement Watchdog Emergency (BWE), Basement Watchdog Combination (DFK961), Basement Watchdog Special+ (BWSP+), Basement Watchdog Big Dog+ (BWD12-120C+) and Basement Watchdog Big Combination sump pump system (BW4000) with Special + backup controller. Look for the + on the upper left hand corner of the BWSP+ and BWD12-120C+ control panel to ensure compatibility.
