Abstract
A backup pump control unit can incorporate ports to receive rechargeable batteries such as lithium ion, nickel cadmium or nickel metal hydride batteries. Multiple units can be coupled together to increase the available, stored electrical energy. In the absence of AC-type input power, the batteries can energize a backup pump.
