What is a Ni-MH battery? Does Ni-MH battery have a memory effect?

What is a Ni-MH battery? Ni-MH battery is a rechargeable battery composed of hydrogen ion and metal nickel. It has 30% more power reserve than nickel-cadmium batteries, lighter than nickel-cadmium batteries, has a longer service life, and has no pollution to the environment. The performance of nickel-metal hydride batteries includes: long service life, high rate charge and discharge, wide temperature use, good energy storage performance, and high stability. Does Ni-MH battery have a memory effect? Ni-MH batteries have a memory effect, but they are very small. The unclear memory effect means that it can be charged multiple times, or even charged every time it is used up, without much impact. Therefore, when using nickel-metal hydride batteries, it is generally possible to charge straight without considering discharging. The rechargeable Ni-MH battery can effectively alleviate the memory effect once a deep discharge every three months. If a battery is not discharged completely this time, then in the subsequent charge and discharge cycles, this part of the undischarged electricity can no longer be discharged. This is the memory effect of the battery. The memory effect generally only occurs in nickel-cadmium batteries, with fewer nickel-hydrogen batteries, and no such phenomenon in lithium batteries. The reason for this is due to the repeated partial charging and discharging of the battery. It will temporarily reduce the capacity of the battery, resulting in a shortened use time. Low-voltage nickel-metal hydride batteries have no memory effect. High-voltage nickel-metal hydride batteries have the same memory effect as nickel-cadmium batteries. Lithium batteries have no memory effect. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete.
