There is a saying that if the rechargeable battery is used properly, the best condition will appear in a certain cycle range, that is, the maximum capacity. This depends on the situation, the sealed nickel-hydrogen battery and nickel-cadmium battery, if used properly (such as regular maintenance, To prevent the generation and accumulation of the memory effect), it will generally reach its maximum capacity after 100 to 200 cycles. For example, after a Ni-MH battery with a factory capacity of 1000mah is used for 120 cycles, its capacity may reach 1100mah. Almost all I can see this description on the graph describing the cycle characteristics of nickel-based batteries in the technical specifications of Japanese nickel-hydrogen battery manufacturers.

　　Nickel-based batteries have the best conditions, 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 than 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 condition. It is worth mentioning that lithium-ion batteries are more susceptible to changes in ambient temperature and exhibit different performance. They will show their best performance at an ambient temperature of 25-40 degrees, while low or high temperature conditions , Its 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, such as placing your mobile phone on the front desk of the car, and it is easy to get direct sunlight at noon 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.
