The Basement Watchdog batteries have been designed specifically to work with the Basement Watchdog backup systems and combo systems. Our maintenance-free batteries are designed to power sump pumps, which means they have longer runtimes and a longer overall product life.

• Standby batteries are made to be discharged and recharged
• Will last longer and perform better than automotive or deep-cycle batteries when used to power a backup sump pump
• Very high reserve capacity means they can power our backup systems continuously for hours or intermittently for days
