“Can this unit be ran just off the battery?”

1-3 of 3 Answers

• Thank you for your question. Relying on the backup battery as the main power source will necessitate frequent battery changes. Battery backup on this First Alert carbon monoxide alarm keeps it working even during a power outage for added peace of mind and security. If you have any additional questions, please don’t hesitate to reach out to our First Alert Consumer Support team at 1 (800)-323-9005.

• Please note that I am not an expert in these alarms. If you were to run the unit just off the two AA batteries, you should check the voltage of each battery on a daily basis, just be on the safe side. However, this is NOT advisable. The owner's manual for the CO alarm clearly states that the unit is not designed to run off of the batteries for an extended period of time.
