In order to give full play to the energy efficiency of the lithium battery and prolong the service life of the lithium battery, pay attention to the maintenance and storage methods of the lithium battery. The specific precautions are as follows:

1. If the lithium battery is not used for a long time, it should be charged with 50%-80% of the electricity, and it should be taken out of the instrument and stored in a dry and cool environment, and the battery should be charged every 3 months, so as to avoid the storage time being too long, and the battery will be self-discharged due to self-discharge. It will cause the power to be too low, resulting in irreversible capacity loss.
2. The self-discharge of the lithium battery is affected by the ambient temperature and humidity. High temperature and humidity will accelerate the self-discharge of the battery. It is recommended to store the battery in a dry environment between 0 ℃ and 20 ℃.
3. Avoid mixing lithium batteries with other conductors. The battery has no protection and is mixed with metal objects such as keys in backpacks, pockets, etc. During the movement, the conductor and the positive and negative electrodes of the battery are in short-term or long-term contact to form a closed circuit, which will cause a short circuit, causing the battery to become hot and "burned out". , leakage, etc.
4. Avoid unprotected use after the lithium battery is broken. Because the battery relies on the battery skin to insulate the positive and negative electrodes, a short circuit will occur after the battery is broken or the battery is completely peeled off and then loaded into the flashlight.
5. Avoid the disorderly storage of multiple lithium batteries. A large number of batteries are not stacked neatly in storage, and each stack of batteries is not separated by insulating objects. Disorderly stacking will cause some batteries to be linked end to end to form a closed-loop short circuit.
6. It is forbidden to store in places with strong static electricity and strong magnetic fields, otherwise, it will easily damage the battery safety protection device and bring unsafe hidden dangers.
7. If the lithium battery emits an odor, heat, discoloration, deformation, or any abnormality during use, storage, or charging, the battery should be removed from the device or charger immediately and stopped.
8. The discarded lithium battery should be covered with insulating paper to prevent fire and explosion.
