Ni MH battery has the best state

There is a popular saying on the Internet that the proper use of Ni MH batteries will be the best in a certain cycle area, that is, the maximum capacity. According to my own experience, this is possible.

The sealed Ni MH battery is properly used in daily use (using a regular matching NiMH battery charger to maintain regular maintenance to prevent the generation and accumulation of memory effects), then the battery may reach the maximum capacity after 100 cycles, for example, saa nimh battery with a nominal capacity of 2500mAh after 150 cycles then the capacity may reach 2600mAH.We can also find the answer from the professional Ni MH Battery Specification, which can be seen in almost all of the nimh battery cycle characteristics described in almost all of the Japanese NiMH battery manufacturers.

There's no best state for li ion batteries

It is also a rechargeable lithium ion battery, but there is no such optimal state. The performance of the li ion battery from the factory to the scrap is gradually reduced, that is, a little bit less at once. We can also see this downward trend in the cycle performance curves of lithium batteries, and there is no sign of a recovery in a circular region like a Ni MH battery. 

It is worth to noticing that the li ion battery is easily affected by the ambient temperature. The li ion battery has the best performance in the range of 25~40 C, but the performance of the lithium battery is greatly reduced at low temperature or high temperature. To make your lithium battery fully play its capacity, be sure to pay attention to the use of the battery and the storage environment, for example, do not put lithium batteries in the sun insolate the car, the sun direct place, because the temperature of these places may exceed 60 degrees.
