How Much is the Storage Capacity of the Lithium Battery Worth Keeping?

In fact, lithium batteries are not afraid of charging, but are afraid of running out of electricity. How do you say? Many batteries have a so-called "charge management IC", which prevents the battery from exploding when it is charged with a safe voltage, and it does not cause the voltage to be too low to start the charging process because of the lack of electricity. Therefore, if the lithium battery is out of power and left uncharged after a long period of time, it is likely that the voltage will be too low and the battery will be discarded prematurely. If the lithium battery is not used for a long time, it is best to retain 40% of the power.

Several factors are considered to determine the main source of this capacity:

1. Lithium-ion battery itself is self-discharged. If it is not charged, it will cause the battery to be over-discharged, which will make the lithium-ion chemical activation purity and reduce the recovery capacity.

2. If the lithium-ion battery is shipped at 100% power, it will bring risks during transportation or storage, because when fully charged, lithium-ion is the most active, and the safety hazard is also the biggest

3. According to the measured data of most battery factories, shipping with 50% power can guarantee its storage for more than one year, the voltage is still above 3.2V, and the recovery capacity is more than 98%.
