What types of Ni-MH batteries?

Types of Ni-MH batteries Ni-MH batteries can be classified according to different characteristics. In addition to standard or general-purpose Ni-MH batteries, from the perspective of special use effects, there are both high-rate type, high-capacity type, and low temperature and High temperature type. Generally speaking, the above-mentioned nickel-metal hydride battery types are put together to form the performance classification of nickel-metal hydride batteries. 1. Standard type: It has general standards for Ni-MH batteries. These standards are composed of the following characteristics: (1) The service life should be between 500 and 1000 times. (2) The sealed and leak-proof, making Ni-MH batteries maintenance-free At the same time, the safety of the battery is effectively guaranteed under the normal state of use and storage. (3) The performance is stable, and it can be used in a wide range of humidity and temperature. The battery has low internal resistance and remains stable after high current discharge. Voltage, (4), scope of application: emergency lights, cordless phones, portable phones, remote controls, electronic dictionaries, toys, etc., almost all mobile power sources without special requirements can be used. 2. High-capacity type (S type): In addition to the characteristics of a standard battery, the battery is made of polymer materials with excellent performance and strict processing technology is adopted, so it can supply energy for a long time to electrical appliances According to this, it is unscientific for some people to call high-capacity nickel-metal hydride batteries also called long-life batteries, because the important advantage of this kind of power lithium-ion battery is high capacity, although it can be expressed as a long life and stable performance, but Starting from the different meanings of the life and capacity of the Ni-MH battery, the high capacity can better explain its characteristics. This battery is mainly suitable for digital cameras that consume more power. 3. High-rate type: This is in terms of its ability to withstand high-rate current. Generally, high-rate Ni-MH batteries can be charged with a current of 1C, and the battery can be fully charged in more than one hour; when discharged with a current of 5C, the battery The median voltage can reach more than 1.24V, and the discharged electricity can still reach more than 90%. Therefore, this battery has excellent fast charging and high current discharge performance, and is especially suitable for high current discharge electrical appliances: such as power tools, large toys (car toys, remote control aircraft), etc. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
