What type of battery does a First Alert carbon monoxide alarm use?

Most detectors take AA or 9V batteries. Use brand-name Duracell, Energizer, or Eveready batteries with an expiration date 4+ years from today's date. Rechargeable batteries are not recommended.

Do First Alert smoke detectors have a battery?

At First Alert, we offer 10-year smoke alarms that have a built-in 10-year battery, which eliminates the need for battery replacements for the life of the detectors. We also offer hardwired alarms with a battery backup, for continuous protection during power outages.

Why does my First Alert carbon monoxide alarm keep chirping?

If your carbon monoxide alarm keeps chirping, the battery may be low or weak. On First Alert carbon monoxide detectors, check to see if the battery light is yellow or green. If the alarm is chirping and the light is yellow, it means the battery is low.
