NiMH Battery FAQs and Information

NiMH batteries are now more widely available than NiCd batteries. They are not as effective as NiCd batteries at delivering high rates of discharge for short periods of time.

The Nickel-Metal-Hydride Battery


  • Here's a little NiMH Battery FAQs history. Research on the nickel-metal-hydride system started in the 1970s as a means of storing hydrogen for the nickel hydrogen battery.
  • Today, nickel hydrogen is used mainly for satellite applications.
  • Nickel hydrogen batteries are large, require high-pressure steel canisters and are costly.
  • In the beginning, metal hydride alloys were unstable in the cell environment and the desired performance characteristics could not be achieved.
  • As a result, nickel-metal hydride development slowed down.
  • More stable hydride alloys were developed in the 1980s, leading to more improved nickel-metal hydride technology.
