Ni-Mh Power Tool Battery

The ni-mh power tool battery is a substitute for the early nickel-cadmium battery. It is the most environmentally friendly power battery. It no longer uses toxic cadmium and can eliminate the pollution problem caused by heavy metal elements to the environment. The ni-mh power tool battery has a large energy density ratio, which means that the use of ni-mh power tool battery can effectively extend the working time of the device without adding extra weight to the digital device. At the same time, the electrical characteristics of ni-mh power tool battery are basically similar to those of nickel-cadmium batteries, and they can completely replace nickel-cadmium batteries in practical applications without any modification of the equipment. Another advantage of ni-mh power tool battery is that the “memory effect” that exists in nickel-cadmium batteries is greatly reduced, which makes ni-mh power tool battery more convenient to use.

Advantages of ni-mh power tool battery :
Nickel-cadmium batteries have better high-current characteristics than nickel-hydrogen batteries, and their anti-overcharge characteristics are also better than nickel-hydrogen batteries. China is also a major producer of nickel-cadmium batteries in the world. Some people have raised the issue of cadmium pollution. China is still exporting a large number of nickel-cadmium batteries and their application products to Europe, which only began to restrict in 2006. According to the news broadcast by CCTV, Shenzhou No. 5 still uses nickel-cadmium batteries. This is the advantage of its relatively high reliability that makes this type of battery still used in aerospace equipment. Looking at it this way, is it too extreme to prematurely withdraw nickel-cadmium batteries from the application of electric bicycles? The cost of nickel-cadmium batteries and the cost of chargers are significantly lower than that of nickel-metal hydride batteries. As long as they are recycled and processed, this type of battery should be retained.
