Is the rechargeable battery in the best condition?

    There is a saying that if the rechargeable battery is used properly, the best state will appear in a certain cycle range, that is, the maximum capacity. This depends on the situation. Sealed Ni-MH batteries and Ni-Cd batteries, if used properly (such as regular maintenance to prevent the generation and accumulation of memory effects), will generally reach their maximum capacity after 100 to 200 cycles, such as After 120 cycles of a Ni-MH battery with a factory capacity of 1000mah, its capacity may reach 1100mah. I can see this description in almost all the graphs describing the cycle characteristics of nickel-based batteries in the technical specifications of Ni-MH battery manufacturers in Japan.

    Nickel-based batteries have the best condition, generally reaching their maximum capacity between 100 and 200 cycles. For liquid lithium-ion batteries, there is no such a cycle capacity hump phenomenon. From the time the lithium-ion battery leaves the factory to the final battery failure, The performance of its capacity is to use once less once. I have never seen any signs of capacity recovery when doing cycle performance on lithium-ion batteries.

     Lithium-ion batteries are not in the best state. It is worth mentioning that lithium-ion batteries are more susceptible to changes in ambient temperature and exhibit different performance. The ambient temperature of 25-40 degrees will show its best performance, while low or high temperature conditions , His performance is greatly reduced. To make your lithium-ion battery fully display its capacity, you must pay careful attention to the use environment to prevent high and low temperature phenomena. It can make it more than 60 degrees, and the battery standby time of users in the north is not as long as users in the south under the same network conditions.
