How do I charge the spare battery in the XanderGlasses II battery case?
The battery case recharges your spare glasses battery and shows its status with indicator lights.
The XanderGlasses II battery case works much like the charging case for rechargeable earbuds and hearing aids. It uses its own internal battery to charge the spare glasses battery seated inside. The spare battery recharges in the case in about 1 hour, and the case can charge the glasses battery 4 times.
Check the status of the battery inside the case
Swivel the lid open and check the light indicator next to the end of the battery:
- Off: no battery.
- Flashing white: the battery is charging.
- Solid white: the battery is charged and ready.
Check the case’s own charge level
The case itself needs to be recharged over time. Swivel the lid open and check the light on the outside of the case:
- Solid red: 0%–30% capacity.
- Solid orange: 30%–60% capacity.
- Solid white: 60%–100% capacity.
Recharge the battery case
If the case’s capacity drops below 60% (solid red or solid orange), recharge it using the included USB-C cable and charging brick, connected to the port on the outside of the case, below the indicator light. It takes up to 90 minutes to fully charge the case from empty. While it is plugged in:
- Flashing red: less than 30% capacity.
- Flashing orange: 30%–60% capacity.
- Flashing white: 60%–100% capacity.
- Solid white: 100% capacity.
