FAQs for 10-Year Battery Smoke and CO Detectors
Why should I choose a 10-year battery smoke and CO detector?
Benefits of owning and installing a 10-year sealed battery alarm in your home would include: no need to change batteries every 6 months, the elimination of late-night low battery chirps, and an end-of-life warning that lets you know when it's time to replace the alarm.
Why are smoke and CO detectors only good for 10 years?
Like most items, combination alarms wear out over time. They should be replaced at least once every 10 years. Any alarm over 10 years old is unsafe and unreliable. Refer to your manufacturer instructions for specific recommendations.
