Introduction to the advantages and disadvantages of nickel-metal hydride batteries

Advantages of Ni-MH battery 1. High energy density (W/kg). No memory effect, long cycle life; low internal output impedance, but not comparable to nickel-cadmium batteries. It can discharge high current, endure overcharge, and has strong overdischarge ability; the general cycle life is 3000 times. 2. Can also deep cycle. High energy density, 1.5 times higher than nickel-cadmium batteries; using nickel-metal hydride batteries, it has been proven to cycle more than 3000 times at 100% deep discharge (DOD). If the depth of discharge is less than 4%, such as 4%, there may be more than one cycle. Durable nickel-metal hydride batteries can withstand excessive charging and excessive discharging, so as to achieve the best battery management requirements. Disadvantages of nickel-hydrogen batteries 1. High self-discharge rate One is high self-discharge rate. In other words, it will consume power if you don't use it, whether it is fully charged or fully discharged. Although not as obvious as nickel-cadmium batteries, they are still affected by memory effects. 2. It has memory, if you want to charge it again, you have to discharge all the power. The battery will age if it is stored for too long. Before reusing the battery, charging and discharging multiple times can also solve this problem. This correction also helps to solve the problem of memory effect. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
