The Liberty StormCell is a battery backup sump pump system built around a 12V DC pump, a 10-amp charger/controller and a water-level activation switch. It keeps pumping when the power fails or the primary pump quits, and the controller sounds an alarm so you know it has kicked in. The battery is not included, so runtime depends on the battery you pair it with. It suits homeowners who already have a primary sump pump and want a second line of defense, and it competes with packaged systems from Zoeller and Wayne that often bundle a battery.

The Liberty StormCell is a battery backup sump pump system that provides backup pumping during a power outage or primary pump failure. It includes a 12V DC pump, a charger/controller and an alarm. A compatible battery is required and is purchased separately.
The 12V DC pump is made in the USA by Liberty Pumps and flows 30 gpm at 10 ft. A microprocessor-controlled, fan-cooled 10-amp charger uses Switch Mode Technology. It can also run as a continuous power supply for the backup pump if the main pump fails. A remote wall-mount interface has an LCD display, with alarm and pump test buttons.
A snap-on activation float with an integral alarm float fits 1-1/4" and 1-1/2" pipe. A high water float acts as a redundant "on" float for the pump. Backup runtime depends on battery capacity, condition and pumping demand.
