Recharge and Restore Lithium-Ion Battery Pack

Follow these steps to restore a depleted battery that may have entered a deep sleep mode:

1. Connect the bike light to a dedicated wall adapter using a high-quality USB cable. Avoid using computer USB ports, as they often lack the current required to wake a dormant lithium-ion cell.
2. Allow the device to charge undisturbed for a minimum of 2-3 hours.
3. Monitor the charging status indicators on the device; a solid or blinking light typically signifies that the battery is accepting a charge.
4. Once the indicator shows a full charge or changes state, disconnect the charger and attempt to power on the light normally.

Safety Precautions: Never leave charging batteries unattended for extended periods. If the device casing is sealed, do not attempt to open it, as internal lithium batteries can be hazardous if punctured or damaged.

Verification: The fix is successful if the light powers on and maintains illumination after being disconnected from the wall adapter.
