Since 1987, the National Fire Protection Association (NFPA) has run the campaign “When you change your clocks, change your batteries.”  Smoke detectors have changed since the beginning, but the principle behind the campaign is the same!

Please follow the tips below from the NFPA that account for multiple types of smoke alarms and their varying battery requirements:

- Smoke alarms with non-replaceable 10-year batteries are designed to remain effective for up to 10 years. If the alarm chirps, warning that the battery is low, replace the entire smoke alarm right away.

- Smoke alarms with any other type of battery need a new battery at least once a year. If that alarm chirps, warning the battery is low, replace the battery right away.  

- When replacing a battery, follow manufacturer’s list of batteries on the back of the alarm or manufacturer’s instructions. Manufacturer’s instructions are specific to the batteries (brand and model) that must be used. The smoke alarm may not work properly if a different kind of battery is used.
