1. Usage Instructions
 
1.Check the battery: Ensure that the battery is charged and installed in the correct direction, such as in a flashlight.
 
2.When using a flashlight, choose the battery based on the requirements of the flashlight and the voltage. Do not use it randomly to prevent damage to the circuit board. Do not use batteries of different models and voltages at the same time.
 
3.While in use, when the flashlight's brightness significantly changes, turn it off to prevent excessive discharge of the battery and charge it in time; Pay attention to the battery's waterproof, moisture-proof, and anti-fall features. After the indicator light changes when charging, remove it in time to avoid overcharging;
 
4.Batteries that have not been used for a long time should be fully charged and maintained, and it is normal to charge and discharge them once every three months or so to avoid chemical corrosion;
 
5.The inner wall of the lamp cup should be kept clean and should not be wiped with the hands or hard objects. To remove fingerprints from the lens, use a cotton swab dipped in lens cleaner to gently wipe it.
 
6.Do not leave the flashlight in contact with sunlight, water, chemicals, or corrosive gases for a long time, to avoid damage to the flashlight.
 
7.Non-professional personnel are not allowed to disassemble the flashlight to prevent damage to the circuit board.
 
Attention Points
 
1.Do not directly shine light into the eyes to avoid causing harm to them.
 
2.Do not exceed the pressure, the voltage should not exceed 4.2V, and please do not reverse the battery, or it will damage the circuit board.
 
3.Please make sure to identify the positive and negative poles of the charger when charging, and do not overcharge or overdischarge the battery to avoid damaging the battery's lifespan (the charging time is usually 5-8 hours).
 
4.When using a flashlight, check to ensure that all threaded areas are tightened without looseness, as this may cause the flashlight to either not light up or to light dimly.
 
5.Torches should be avoided from being placed in direct sunlight or high-temperature environments. After use, please remove the batteries and store them in a cool and dry place after fully charging.
 
6.The company's flashlight has the ability to withstand daily water exposure, and it usually doesn't have any problems after being exposed to rain. However, it is not designed for diving, so please do not take this flashlight diving or leave it in a water basin or bathtub for a long time.
 
7.To maintain the smooth rotation of O-rings (sealing gaskets) and screw threads, please apply Vaseline oil to their surface every 2-3 years.
 
Charging Instructions
 
    If the battery is not fully charged, it should be charged in time to avoid affecting the battery life. Even during long-term storage, the battery should be charged.
