The Basement Watchdog Maintenance Free (AGM) Standby Battery for Backup Sump Pumps (BW-27AGM)
Features of The Basement Watchdog Maintenance Free (AGM) Sump Pump Battery
Longer Runtimes
The Basement Watchdog batteries are designed in conjunction with our sump pump systems making them the perfect power source for your pumping needs. This allows your backup pump to run continuously for hours or intermittently for days to keep your basement dry.
Unique Construction
The standby construction of The Basement Watchdog Sump Pump Battery (Model BW-27AGM) allows it to last longer and stay viable for years. Its design and construction ensures the battery is kept at peak charge without having to be discharged and recharged to maintain its health.
Made to Power Pumps
Both our wet-cell and maintenance-free Basement Watchdog batteries are designed to power sump pumps, which means they last longer and perform better than standard automotive or deep-cycle batteries.
No Maintenance Required
If you are looking for a maintenance-free option, The Basement Watchdog AGM battery is your solution. No battery fluid to add, no water every 6 months—just connect the system and you are ready to go. All current Basement Watchdog Battery Backup and Combination systems are designed to work with the maintenance-free AGM battery.
