Change Your Clock, Change Your Batteries™

It’s that time of year again! Change Your Clock, Change Your Batteries™!

For 29 years, Energizer® brand has partnered with the International Association of Fire Chiefs (IAFC) to keep families safe through the Change Your Clock Change Your Batteries™ program. Every fall, Energizer and the IAFC work to remind people of the simple, life-saving habit of changing and testing the batteries in smoke alarms and carbon monoxide detectors when setting the clocks back for daylight saving time.

  • Daylight Saving Time (U.S.) 2024 begins at 2:00 AM on Sunday, March 10

The National Fire Protection Association reports that 71% of smoke alarms which failed to operate had missing, disconnected or dead batteries.
