FAQs for 10-Year Battery Smoke Detectors
What is a 10-year battery smoke detector?
Battery powered smoke detectors use 10-year sealed lithium batteries and provide continuous protection with no need to replace the battery for the lifetime of the detector.
Do 10-year battery smoke detectors really last 10 years?
Yes! These detectors are powered by sealed, long-life lithium batteries for 10 years, giving you a decade of peace of mind, even during power outages.
Does the law require 10-year sealed smoke detectors?
There is a growing trend of switching from traditional battery powered smoke detectors to detectors that use 10-year sealed batteries. Many countries or states are starting to require this type of smoke detector. Smoke detectors have a limited lifespan and should be replaced every 10 years.
What are the benefits of installing a 10-year sealed battery detector?
10-year sealed battery smoke detectors are powered by sealed lithium batteries that have a life span of 10 years. These detectors provide 10 years of continuous protection, even during power outages, and spare you the hassle of frequent battery replacement for the lifetime of the detector. All smoke and fire detectors should be replaced at least every 10 years and tested regularly to ensure the detector is functioning properly.
Are 10-year sealed smoke detectors better than hard-wired smoke detectors?
There are advantages to both systems. Hard-wired smoke detectors tie into your home’s wiring and require professional installation, but generally do not require battery changes unless they feature a backup battery. 10-year sealed battery-only detectors are simple to install, and can work during a power outage. Battery-operated smoke detectors, sealed or not, should be tested on a regular basis. When the battery wears out in a 10-year sealed detector, the entire unit must be replaced, which helps prevent outdated units from staying in circulation.
Are they generally more expensive than non-sealed alarms?
No! Most 10-year sealed smoke alarms range in price from roughly $20-$40, making the initial investment slightly higher than a non-sealed alarm, but non-sealed alarms require annual battery changes. The cost of these replacement batteries averages $38 over a 10-year lifespan, meaning that they ultimately cost more than the sealed version.
