Zoeller 164084 Agm Deep-cycle Backup Battery 72ah 12V

Product Description

The ZOELLER 164084 is a sealed AGM (Absorbent Glass Mat) deep-cycle battery engineered as a backup power source for 12-volt DC sump pump systems. Its valve-regulated, maintenance-free construction eliminates electrolyte checks and fluid refills, making it well-suited for restricted-access installations such as crawl spaces and finished basement utility areas. Rated at 72 amp-hours nominal capacity, the 164084 delivers approximately 57 hours of continuous run time under standard load conditions. Licensed plumbers and pump system technicians install this battery as a direct power source for battery-operated sump and effluent pump backup units.

This battery is designed for residential and light commercial basement drainage applications where power continuity during outages or primary pump failures is critical. It is intended for use with 12-volt DC battery backup sump pump systems, including the Zoeller Basement Sentry Series. The sealed AGM design is appropriate for indoor, enclosed, and semi-conditioned spaces where a maintenance-free power source is required and vented wet-cell batteries would be unsuitable.

Compatibility

Designed for use with 12-volt DC battery-operated sump pump systems, including the Zoeller Basement Sentry Series. Confirm voltage and terminal configuration against your specific pump controller before installation.

Installation Notes

Installation is typically performed by a licensed plumber or pump system technician familiar with low-voltage DC backup systems. Disconnect the pump controller from AC power and isolate the existing battery before service. Verify polarity and terminal type before making connections — reversed polarity can damage the controller and void the warranty. Follow local electrical and plumbing codes for battery backup sump system installations.
