Analyze the correct charging method for lithium batteries

1. Recharging a new battery A new battery generally needs to be activated. After the battery is left for a period of time, it will enter a dormant state. At this moment, the capacity is lower than the normal value and the use time is shortened. Therefore, activation is required. Lithium battery activation method is very simple, as long as 35 normal charge and discharge cycles can activate the battery and restore normal capacity. 2. Charging the old battery 1. Charging method The old battery refers to the battery that has been charged and discharged many times, not the scrapped battery. The life of a lithium battery has nothing to do with the number of charging and discharging. It has no memory effect. No matter how you charge it, it will not affect the number of charging cycles. Therefore, don't charge the battery until it is completely empty. It is best to charge the battery as much as possible when you can charge it. The charging time should be within 2-3 hours. Of course, you don't have to be fully charged. 2. The safe operating voltage scale of the charging voltage lithium battery is 2.8 to 4.2V. Lower or higher than this voltage scale, the lithium ions in the battery become very unstable, and even cause trouble. To ensure that the battery is on a safe scale, a special charger is required. These chargers will automatically adjust the charging method according to the current battery condition. 3. To charge things, lithium batteries should be charged with a special charger, which can guarantee the safety of charging. When the charger works, it charges the battery with a stable current. As the battery voltage increases, the charger increases the charging voltage together to accelerate the charging speed. When the battery reaches the 4.2V cut-off voltage, the battery is only charged into about 70% of the power at the moment (not full). At this moment, the charger continues to charge the battery with a steady voltage and a gradually decreasing current. When the value is less than 0.1A, the battery voltage continues to rise and it stops charging. 4. Lithium batteries that are not needed for long-term charging on time should be stored in a cool and dry place in a half-charged state. Storage with full power is risky and the battery will be harmful, while storage without power may damage the battery and lose the effect. During the registration process, every 3--6 months, a charging cycle must be completed and a power calibration will be done.
