The Laser Smart Internal Door Lock with Fingerprint has a built-in 400mAh rechargeable battery. It charges from a 5V USB source through the USB-C port on the exterior knob assembly.
To charge:
1. Connect a USB-C cable to the lock's charging port.
2. Connect the cable to a compatible 5V USB source, such as a power bank, laptop or wall adaptor.
3. Allow up to 3.5 hours for charging from empty.
4. Check the remaining battery level in the Connect SmartHome app and recharge when low.
If the battery goes flat and the door is locked:
- Use one of the supplied mechanical keys, or
- Connect a suitable external 5V USB-C source to temporarily power the lock.
Recharge the battery once access is restored.
The charging cable and USB power source are not included. Keep the mechanical keys somewhere accessible but separate from the door, and keep a compatible power source available. Battery life varies with usage and Bluetooth activity.
