The basic properties of Ni MH batteries

Ni MH battery, is a new generation of high-energy two battery after Cd-Ni battery. Because of its high capacity, high 

power, and pollution-free characteristics, it has been favored by people. It is one of the important development 

directions of the two battery today. Compared with the Cd-Ni battery, the capacity of Ni MH battery is increased by more 

than 50%, which eliminates the pollution of Cd to the environment. Fast charging can be realized, and the working voltage 

of Ni MH battery is 1.2V.  It can be used interchangeably with N i-Cd battery; Ni MH battery has higher energy storage 

capacity than Cd-Ni battery, the specific energy of high energy MH-Ni battery can reach 95W h/kg, the specific power of 

high power MH-Ni battery reaches 900W/kg, and the cycle service life is more than 1000 times. The working environment 

temperature is -40~+55 C, and the Ni MH battery has little loss at high and low temperature.
