Little Giant SPBS-12 battery backup sump pump
1 1/2", 1,600 GPH, 1/5 HP, 115V, Homeowner grade battery backup sump pump.
Provides extra protection in the event the primary unit fails, an obstruction in the pit blocks flow, or a power outage occurs.
The back up system is powered by a 12 VDC battery (not included). The battery should be a deep cycle marine battery rated 105 to 140 amp-hours.
The Little Giant back up sump pump system also functions as an alarm system if the primary pump fails to empty the sump pit.
A 140 amp-hour battery can provide in excess of 9 hours of pumping time (If the unit pumps for 5 minutes out of every hour, that is over 4 days of use without electrical power).
A controller/charger monitors the battery condition and charges the battery when required. It also alerts the homeowner when the system has operated or when possible flooding conditions exist.
