Knowledge Of Selling Batteries

January 09,2023
  Nickel-metal hydride batteries (Ni-MH) are improved from nickel-cadmium batteries (Ni-Cd batteries), which replace cadmium (Cd) with metals that can absorb hydrogen. It offers higher capacity, less noticeable memory effect, and less environmental pollution (does not contain toxic cadmium) than Ni-Cd batteries at the same price.
Its recycling efficiency is better than that of lithium-ion batteries, and it is known as the most environmentally friendly battery. However, when compared with lithium-ion batteries, there is a certain memory effect. The new Ni-MH batteries now have very low self-discharge (similar to alkaline batteries), and can work at low temperatures (-20°C). Ni-MH batteries have a larger output current than carbon-zinc or alkaline batteries, and are relatively more suitable for high-power consumption products.
  The capacity of Ni-MH batteries is relatively high (in terms of volume). Taking AA batteries as an example, the marked capacity of Ni-MH batteries can reach 2900mAh (milliampere-hours, or "mAh" for short), while alkaline batteries only have ~2100mAh (However, the initial discharge voltage of alkaline batteries is generally higher than that of nickel-metal hydride batteries), and of course it is much higher than the 1100mAh of the first generation of nickel-cadmium batteries, but it is still not as good as lithium-ion batteries.
  Alkaline batteries may leak slightly corrosive and harmful liquids after a long period of non-use (which can be harmful to the human body or damage the device using the battery), while lithium batteries may burn or explode when improperly used. Relatively speaking, Ni-MH batteries are relatively safe batteries.
