The battery is a consumable, and its life is certain (charging and discharging times are usually 300-500 times). Therefore, mastering the correct use method is the secret of "prolonging the life" of the battery. Different types of batteries have different charging requirements. Ni MH battery is prone to heating and high temperature problems during charging. If the heat can not be released in time, it is very easy to cause battery degradation or irreversible damage or even explosion. Generally speaking, the battery can be charged with the charger attached to the battery (or the original charger) according to the requirements of the manual. It is forbidden to charge the battery for a long time without interruption or with a charger that does not meet the requirements (especially the low-grade charger has no protection function) to avoid damage or danger. The correct method is to charge the battery with a qualified or original charger, and remove it after the charging time is reached. Generally, the lithium battery has a relatively complete protection function (with a protection plate), and there are not many other requirements for charging the battery. However, in order to prevent the safety problems caused by the failure of the overcharge protection function of the protection plate, it is not recommended to charge the battery for a long time. The battery should be taken out after being fully charged. In addition, the original charger or the charger attached to the battery must be used when charging, and the operation and use must be carried out according to the instructions, otherwise the battery may be damaged or even dangerous; The probability of overheating, explosion and ignition of lithium batteries is much higher than that of other types of batteries. Recently, Apple and Dell have similar cases; In addition, there should be no inflammable and explosive articles attached to the battery or charger during charging, such as newspapers and magazines.

Before using the battery, check whether it meets the load requirements. If the battery cannot meet the load requirements or the current is high (more than 1C), the battery will be damaged or its life will be shortened.

Since long-term storage will accelerate battery self discharge and active substance passivation, the ambient temperature and humidity is between 10 ° C and 30 ° C 65 ± 20%. At the same time, to reduce the negative impact of battery self discharge and active substance passivation caused by long-term storage (such as more than one year), the battery needs to conduct a charge discharge cycle every three months to restore its original performance.
