Precautions for use:

1. Do not reverse the positive and negative poles when charging, otherwise the battery may be discarded (the positive pole with "+" number faces the head of flashlight).

2. Tips: The battery is likely to be scrapped once the lithium battery is fully discharged. Therefore, do not drain the battery when using it. When using it, the flashlight should be charged immediately when the brightness is obviously dimmed.

3. Do not disassemble the lamp holder frequently to avoid reflective cup or bulb damage. The lamp holder part is an integrated circuit system, and the bulb is welded on the IC board, which cannot be repaired by non-professionals. The focus has been corrected when it leaves the factory flashlight. If it is unscrewed, please adjust the lamp nut to correct the focus. Please be careful to control the temperature change of flashlight and keep the heat dissipation.

4. Use a "three-proof" charger that prevents overcharging, reverse connection, and short circuit.

5. Do not use batteries indiscriminately. Use batteries of the specified model and voltage to prevent the circuit board from being burnt out.

6. If the battery is not used for a long time, the battery should be fully charged and then stored. It should be charged and discharged once in about three months.

7. Charging time: 3-5 hours (with indicator light prompt after charging); Do not overcharge or overdischarge.
