lithium 3400mah 3.7v 18650 battery.What is the correct usage method for button type nickel hydrogen batteries

　　1、 New batteries need to be charged before use

　　Generally speaking, newly purchased nickel hydrogen batteries contain a small amount of electricity, and many people discover that there is already electricity inside the battery after purchasing, and then use it directly. This approach is not correct. Even if the battery purchased first contains electricity, it still needs to be charged before use, because nickel hydrogen batteries need to go through three to four charges to stimulate their performance and maintain a better state. Therefore, when purchasing new batteries, they must be fully charged before use.

　　2、 Run out of battery before charging

　　The button type nickel hydrogen battery has its own characteristics, such as its small memory effect. It is recommended to charge the battery as much as possible after running out of charge during each use, and to ensure that the battery is fully charged at once during the charging process, instead of frequent power outages and intermittent charging. The purpose of doing so is to extend the service life of the battery, so that it can maintain good performance for a long time. The charging process also needs to pay attention to the heat dissipation of the battery.

　　3、 Long term idle maintenance

　　If the nickel hydrogen battery has been idle for a long time, it needs to be taken out of the battery compartment and not kept inside, otherwise it will accelerate the loss of battery performance. Idle nickel hydrogen batteries should be placed in a suitable location for proper storage, ensuring ventilation and dryness throughout the storage environment. Avoid placing them in damp environments, as this may lead to battery short circuits. When it is used again after being idle for a long time, it is necessary to charge it first.
