How much is the best lithium battery power to maintain?

How much is the best lithium battery power to maintain? Someone once told me that it is best to keep the power of a lithium battery between 40% and 60%, but why is it because keeping the power between 40% and 60% is worthy of storage performance. Lithium batteries generally have a factory capacity of about 50%, which is the best storage capacity verified by the battery factory. Lithium batteries are not afraid of charging, but are afraid of running out of electricity, how to 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 will not start the charging process because the voltage is too low because of no electricity. Therefore, if the lithium battery is dead 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 early. If the lithium battery is not used for a long time, it is best to retain 40% of the power. As a way to check product quality, if the self-discharge rate of some batteries in the same batch is too high, it means that there are defects in their own quality, and they have to be selected and disposed of separately. Normally, the self-discharge rate doubles every time the battery temperature increases by 10°C. The monthly self-discharge of lithium batteries is about 1~2%, while the monthly self-discharge of various nickel-based batteries is 10-15%.
