Batteries aren’t the only thing to change—every detector has a 10-year lifespan, so check the date before it overstays its welcome.

Why It’s Time to Do More Than Just Change Your Smoke Detector Batteries:

We’ve all been there: it’s 1:00 AM, and the smoke detector starts chirping. While most people know they should replace their smoke detector batteries twice a year, what often gets overlooked is that the detector itself has a lifespan of about 10 years.

Batteries Aren’t the Only Maintenance:

Changing batteries regularly is important, but the detector itself contains sensors that wear out over time. After a decade, those sensors can fail to detect smoke as effectively—even if the unit still powers on.

Look for the Expiration Date:

Every smoke detector has a manufacture date and expiration date printed on the back or inside the unit. Most expire at 10 years, regardless of whether the batteries are new. If yours is past that date, it’s time to replace the entire unit.

Signs It’s Time to Replace:

• Your smoke detector is more than 10 years old.
• It chirps even after a fresh battery is installed.
• The test button doesn’t sound as strong or responsive.

Replacement Options:

Many new smoke detectors come with sealed 10-year batteries. That means you won’t need to worry about battery swaps every six months—the whole unit is replaced at the end of its lifespan. This eliminates the dreaded late-night chirping.

Safety First:

According to the National Fire Protection Association, working smoke alarms cut the risk of dying in a home fire nearly in half. That makes replacement just as critical as regular battery checks.

Quick Tip:

When you replace your detector, mark the installation date on the inside cover. That way, you’ll know exactly when the 10 years is up and you can stay ahead of the expiration.
