Charging the Battery
The Trelock LS 950 uses a rechargeable lithium-ion battery and comes with a USB charging cable.

- Open the rubber flap and insert the small end of the USB charging cable into the light's port.
- Connect the larger end of the USB cable to a compatible USB power source (e.g., computer USB port, USB wall adapter).
- The LCD display will indicate the charging status. A full charge typically takes several hours.
- Once fully charged, disconnect the cable and securely close the rubber flap over the USB port to maintain water resistance.
