When the battery back-up becomes weak, the Smoke Alarm will â€œchirpâ€ about once a minute (the low battery warning). This warning should last 7 days, but you should replace the battery immediately to continue your protection. Choosing a replacement battery: Your Smoke Alarm requires one standard 9V battery.
The battery in your smoke alarm should be something that you can rely on with absolute certainty, so we recommend a 10-Year Sealed Battery Smoke Alarm.
