Safety lamp User Guide:
1. There's no need for initial charging for High-duty Lithium Mineral Lamp, it can be used immediately after daily charging.
2. Stable voltage parallel connection charging method is adopted in daily charging in a cradle, the charging voltage
is 4.2V ± 0.05V, charging last for 8-12 hours. When the charging voltage reaches the maximum value, the electric circuit will be automatically powered off to stop charging.
3. During the charging, the charging voltage is higher than the rated voltage of the bulb, therefore the switch of the socket should be switched off to avoid burning off of the bulb.
4. The charger must be used to ensure the usage duration of the battery.
Daily maintenance:
1. In case of short-circuit, the protection circuit will cut off the power at an instant. After the problem of short-circuit is solved, re-switching on of the lamp would restore the usage.
2. The mineral lamp can't be used or stored in a environment of over 60oC and should be stored in a low-temperature and dry environment. When long-term storage is needed, charging should be done half year, 50% charging capacity should be reached each time.
