The Basement Watchdog BW27AGM is a sealed AGM (Absorbent Glass Mat) standby battery designed to provide backup power for compatible Basement Watchdog sump pump systems. During power outages, this battery keeps your sump pump running to protect your basement from flooding and water damage.
This maintenance-free battery eliminates the need to add battery fluid or distilled water, making it a hassle-free solution for long-term backup power. The sealed AGM design provides years of reliable service without ongoing maintenance. By connecting two batteries in parallel (jumper cables required separately), you can extend runtime significantly, giving you greater protection during extended outages.
