The Pawscout App will alert you when your battery is low. Also, if you push the raised button on the front of the Pawscout Tag and fail to see a blinking blue light (it's quick and easy to miss, so test it in a dark location), it is time to replace the battery.

The battery should last up to 6 months, depending on usage.
If you change the battery of your Pawscout, make sure the lock icon aligns with the tab to keep the unit waterproof.
