More details on the Flo by Moen Battery Backup

Mark G.

Product Research


Overview: The Battery Backup (920-001) keeps your Flo by Moen device working in the event of a power outage. The weatherproof battery backup is outdoor-rated, and installs in-line between the Flo device and the power supply. During normal operation, it passes 12-volt DC power to the Flo by Moen device and keeps the built-in battery topped off. If there is a disruption of the AC line, the Flo device automatically switches to the battery backup to maintain power. The battery backup has a 6' output cord, which extends the overall length of the Flo by Moen power cord. The Battery Backup is covered by a 1 year warranty.

Backup Power: The Flo by Moen Battery Backup has a rating of 13,000mAh at 10.4 VDC. It works with both 3/4" and 1-1/4" sizes of the Flo by Moen device. The battery backup will provide power for over 3 days, in the event of a power outage.

Status LED: The battery backup includes an LED on the front to indicate its operating status: Full charge (green), Charging (solid red), and Error (flashing red).

Power Supply: The Battery Backup should only be used with the Flo Outdoor Rated Power Adapter (820-00014), which is supplied with the Flo by Moen device.
