To maximize the energy efficiency of lithium batteries and extend their lifespan, pay attention to proper care and storage. Specific precautions are as follows:
1. When not in use for an extended period, lithium batteries should be charged to 50%-80%, removed from the instrument, and stored in a dry, cool environment. Charge the battery every three months to prevent self-discharge, which can lead to low battery capacity and irreversible capacity loss.
2. Lithium battery self-discharge is affected by ambient temperature and humidity. High temperatures and humidity accelerate self-discharge. It is recommended that batteries be stored in a dry environment between 0°C and 20°C.
3. Avoid mixing batteries with other conductive objects. If unprotected batteries are placed in backpacks, pockets, or other places with metal objects such as keys, brief or prolonged contact between the positive and negative terminals of the battery during exercise can create a closed circuit and short circuit, causing the battery to overheat, burn out, or leak.
4. Avoid using batteries without protective covers if they have been damaged. Because batteries rely on the insulation between the positive and negative terminals, a broken battery or completely peeled battery cells can cause a short circuit when installed in a flashlight.
5. Avoid storing multiple batteries in disorder. Large batches of batteries that are not neatly stacked and separated by insulating materials can cause some batteries to connect end to end, creating a closed loop short circuit.
6. Avoid storing batteries in locations with strong static electricity or magnetic fields, as this can damage the battery's safety features and create safety hazards.
7. If a battery emits an odor, becomes hot, changes color, deforms, or exhibits any abnormality during use, storage, or charging, immediately remove the battery from the device or charger and discontinue use.
8. Wrap the electrodes of discarded batteries with insulating paper to prevent fire or explosion.
