Lithium battery life and charging times to complete the cycle on , and there is no direct relationship between the number of charge cycles .
A charge cycle means that the battery fully to discharage to empty, and then charge fully by the process. This is not equivalent to a single charge. Its significance is shown below.
The figure shows , the first charge 40% , with a period of time and later charged 20% , after working then charged 30% , then next 20% ...... 20% in the middle , or just supplement 10 % of its electricity , the total accumulated a charge cycle . After the next cycle.
For example ,first day only use half power of the battery, and then it is fully charged. Next day make the same action,this can only be counted as one charge cycle , not two . So , usually it may take several complete a charge cycle. Each complete a charge cycle; the battery will be reduced a little. However, the decrease was very small, the high -quality battery charge cycle many times, still retains 80% of the original capacity .That's the reason a lot of lithium-powered products still use as usual after two or three years. Of course, the life of lithium to eventually need to be replaced.
Lithium battery life is generally 300 to 500 charge cycles. Assuming a full discharge of electricity for the Q, if not consider reducing electricity consumption after each charge cycle , the total lithium in their life can provide or supplement 300Q-500Q for electricity . Thus, we know that if each with 1/ 2 the charge, you can charge 600-1000 times; If each with 1 /3 of the charge, you can charge 900 to 1500 times. So , if the random charging , indefinite number of times . In short, no matter how charge, 300Q ~ 500Q added into the total power that is constant. So, we can understand this: Lithium battery life and battery charge related to the total charge and charge cycles irrelevant. Put deep charge deep and shallow charge and discharge shallow impact the life of lithium or less
To play a maximum performance of lithium-ion batteries, often need to use it, so that the electronic lithium battery is always in flux.
