What kind of common sense of battery maintenance?

Battery maintenance tips and storage: batteries that have not been used for a long time should be taken out of the electrical device and stored in a relatively low temperature and dry environment (0-20°C) to prevent mixing with metal conductive materials. It is better to charge the rechargeable battery at about 50% before storage. When using it again, charge and discharge with a small current. Charging: Use small current charging as much as possible, especially for batteries used for the first time. High-current chargers must have intelligent detection and protection functions. High-current charging will damage the battery life. Overcharging may cause damage to the battery (overheating, leakage, explosion), and use should be avoided as much as possible. It should be charged in a normal temperature environment as much as possible, and the charging efficiency in a high temperature environment will decrease. Discharge: When the battery is discharged to a low voltage state that cannot work effectively, the power should be cut off in time. The minimum working voltage of a nickel-hydrogen/nickel-cadmium single-cell battery is 0.8V. The lithium battery is controlled by a protection device. Overdischarge can damage the battery. Pay attention to observation: During use, you should pay attention to observe the changes in the appearance of the battery, the heating of the battery during charging and discharging, the changes in the charging time and discharging time of the battery, and stop using it if there is any abnormality. Prevent mixed use: When using more than two batteries in groups, confirm the consistency of the batteries: the same brand, the same charging and discharging history, and the same state of charge. Excessive differences in performance and state of charge between batteries will cause some batteries to overcharge and some batteries to overdischarge, and cause accidents in severe cases. Performance recovery: Complete charge and discharge once or twice every two to three weeks. Special note: The battery should be prevented from falling, impact, puncture, short circuit, water immersion, rain, and keep away from fire and children.
