A Lithium Manganese Dioxide battery for digital cameras charge cycle means that all of the battery's charge is from full to empty, and then from empty to full, which is not the same as charging. To put it simply, the 600 mAh lithium battery, you first charge from 0 mA to 400 mAh, use ah with N mAh; then you charge 150 mA, then use N mA Ann; finally recharged 100 mAh, when the last charge to 50 mAh, a charge cycle for this battery is here.(400+150+50=600) A lithium battery used only half of the electricity on the first day, and then fully charged it. If it is still the next day, it will be charged in half, and it will be charged twice in total. This can only be counted as one charging cycle, not two. Therefore, it is usually possible to complete a cycle after several charges. Each time a charge cycle is completed, the amount of power is reduced a little. This is why many people who use lithium battery mobile phones often say: "This broken mobile phone can be used for 4 days, but it can only be used for 3 days and a half."

However, this power reduction is very small. After a high-quality battery has been charged for many cycles, it will still retain 80% of the original power. Many lithium-powered products will still be used after two or three years. Of course, the life of the lithium battery will eventually need to be replaced.

The life of lithium batteries is generally 300-500 charge cycles. Assuming that the amount of power supplied by a full discharge is 1Q, if the power consumption is reduced after each charging cycle, the lithium battery can provide or supplement 300Q-500Q power in its lifetime. From this we know that if you charge 1/2 each time, you can charge 600-1000 times; if you charge 1/3 each time, you can charge 900-1500 times.

By analogy, if you charge randomly, the number of times is variable. In short, no matter how charged, the total power added to 300Q-500Q is constant. Therefore, we can also understand that the life of the lithium battery is related to the total charge of the battery, regardless of the number of times of charging. The effect of deep deep charge and shallow charge on lithium battery life is not much different. If you want to learn more about 3.6V 2000mah Li-SOCl2 battery,you can contact us.
