Zoeller's Aquanot 508 battery backup sump pump system provides extra protection when a primary AC pump shuts down due to a power outage or another electrical problem. An automatic, 10 amp, UL-recognized charger/controller with battery burnout and overcharge protection maximizes battery life and provides over 7 hours of continuous pumping. All necessary pipes, valves, and fittings are included to transform your existing system into a complete AC/DC sump pump system. The alarm, light indicator, and warning system ensure peace of mind for the homeowner.
