1. Usage Instructions
 
1.Check the battery: Ensure that the battery is charged and installed in the correct direction, such as in a flashlight.

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;
