How Much Power is Stored in the Lithium Battery?

Sep. 13, 2021

As a lithium battery supplier, I'd like to introduce it to you.

In fact, lithium batteries are not afraid of charging, but are afraid of running out of electricity. How do you say? Many batteries have so-called "charging management ICS", so that the battery will not explode when it is charging, and it will not cause the battery 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 self-discharges, if it is not charged, it will cause the battery to be over-discharged, thereby making the lithium-ion chemical activation purity and reducing 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%.

Can reduce the number of recharges to extend the life of the lithium battery?

The current lithium battery capacity loss is calculated by charging "cycles". According to Apple's official statement, the calculation of the number of cycles is based on the cumulative percentage of each battery discharge as a charging cycle, that is, the battery starts from 0 A charge cycle is counted as 100%. If it is charged from 50% to full charge, it is considered a half charge cycle. It does not mean that one charge is one cycle. Therefore, there is no need to wait until the battery is low before charging.

Lithium batteries have no memory effect and can be recharged at any time. In order to reduce the number of recharges, deliberately using up the battery before fully recharging it will not extend the battery life, but will have a negative impact on the battery life.

In fact, lithium battery charging pays attention to "eat less and more meals", and frequent shallow charging and discharging can help extend its life.
