The LED light in the charger turns on when you start charging the ring. When the light blinks, your ring is charging (but is not fully charged). When the light stops blinking, the ring is fully charged.
Charging the ring battery up to 100% takes 20–80 minutes, depending on how often you charge the ring.
If the charger light doesn't go on:
- Check that the charger cable is connected properly.
- Make sure that the ring is positioned correctly, and pressed all the way down.
