Can you change the battery in a FireAngel smoke alarm?
The FireAngel ST-622, ST-620 and SI610 alarms all have lifetime batteries that cannot be replaced. The batteries in these alarms last for 10 years and after this time, the complete smoke alarm should be replaced. These FireAngel alarms can easily be replaced with an UltraFire Longlife Smoke Alarm Kit that fits onto your original FireAngel base.
The FireAngel SI-601 and SO601 smoke alarms have batteries that can be replaced. The alarm will alert you with a low battery warning. The SI-601 and SO-601 alarms last for 10 years and after this time the complete smoke alarm should be replaced. As these models are now discontinued, you can purchase a FireAngel replacement alarm that fits on to your original FireAngel base.
