Smoke detectors can use different types of batteries, but the most common ones are 9V and AA alkaline batteries. Some smoke detectors use coin cell batteries, and some come with a built-in battery that lasts for the life of the detector.
The battery type used in a smoke detector depends on the model and manufacturer. However, it is important to choose a reliable battery that you can depend on for your home and familys safety. First Alert recommends a 10-Year Sealed Battery Smoke Alarm, which contains lithium batteries that last for the life of the alarm, eliminating the need for battery replacements.
When using batteries like 9V or AAs in your smoke detectors, its important to check them consistently and replace them every six months. A good reminder is to change your smoke detector batteries every time you change your clock for Daylight Saving Time.
In summary, smoke detectors can use different types of batteries, but the most common ones are 9V and AA alkaline batteries. It is important to choose a reliable battery and replace it every six months to ensure that your smoke detector functions properly and keeps your home and family safe.
