Are there any alarms that do not work with the Roost Smart Battery?

 

Our new Version 2 batteries, shipping after October 18, 2017 should not experience compatibility issues with the alarms listed below that cause a low-battery chirp. You can tell if you have a Version 2 battery because the Roost logo on the bottom of the battery is white. 

If you purchased your Roost batteries prior to October 18, or purchased older batteries via an unauthorized reseller, this article is relevant for you.

While the Roost Smart Battery works in most smoke and combined smoke/CO alarms, we have discovered compatibility issues with our Version 1 batteries and the following alarms (see table below). If you are located in the United States and your alarms are not certified to UL or ETL standards we cannot warrant the Roost Smart Battery in your alarm. If your alarm is on this list and you have Roost Version 1 batteries, you may want to consider replacing it, especially if it is older than 10 years old. Please see our Help Center Article: When should I replace my smoke alarm?
