The Wearsafe Tag SOS button uses a standard CR2032 coin cell battery which lasts 3 to 6 months with normal use, no charging needed. Tag SOS button vibration is the greatest drain on battery power, so frequent alerts or Tag testing can reduce battery life significantly.
The Tag SOS button is an always-on device. As long as the Tag is within range of your paired phone running the Wearsafe App in the background, it is working. You don’t need to take any other steps in order to be prepared. If you are storing your Tag for an extended period of weeks or months, we recommend removing the battery while it is stored, and reinstalling when you’re ready to use the Tag again.
