What does the charging cycle of a lithium battery mean?

A lithium battery used only half of its power on the first day, and then overflowed with electricity; the next day, it was charged with half of its power, and it was charged twice in total. This can only be counted as one charging cycle, not two. Therefore, it may usually take several times of charging to complete a cycle. Every time a charging cycle is completed, the power will decrease a bit. In other words, the lithium battery charging cycle is an expression of the lithium battery power, which means the process of the battery power from full to empty and then from empty to full. From the perspective of the voltage in the existing battery design, a single lithium battery has been used from 4.2V without load (the capacity is the nominal capacity) to 2.75V (the capacity is zero at this time) and then the reverse process is completed. Charging cycle. In fact, the life of a lithium battery is determined by the charging cycle. In daily life, it may take several times to complete a cycle. The battery capacity will decrease a little after completing a charging cycle, but the reduction in power is very small. High-quality batteries will still retain 80% of the original capacity after being charged for many cycles. Many lithium-powered products will still be used as usual after two or three years.
