NiMH battery and accumulator (Nickel Metal Hydride)

A NiMH battery, which stands for Nickel Metal Hydride battery, is a rechargeable battery widely used in various electronic devices. It is an improved version compared to the older Nickel Cadmium (NiCd) batteries. NiMH batteries have a higher capacity, meaning they can store more energy. Additionally, they are less susceptible to the memory effect and are more environmentally friendly as they do not contain heavy metals.



Little maintenance

NiMH batteries (Nickel Metal Hydride batteries) are not significantly affected by the ‘memory effect’. This makes them very easy to maintain and requires almost no special care. Additionally, NiMH batteries are environmentally friendly as they do not contain heavy metals. These are some significant advantages of NiMH batteries compared to, for example, NiCD batteries. Furthermore, NiMH batteries are known for their longer lifespan, rechargeability, and broad applicability in various devices, making them a popular choice.


Examples of NiMH batteries

Elfa has a wide range of batteries in stock that might be of interest to you. Elfa offers a broad selection of AA NiMH rechargeable batteries and AAA NiMH rechargeable batteries from brands such as Varta, GP, and Duracell. A recommended option is the Varta Recharge Accu Power 2600mAh AA Blister 4 1.2V. This rechargeable NiMH battery from Varta is efficient, made of high-quality materials, and represents an environmentally conscious choice.

Advantages of nickel metal hydride batteries

  • 30-40% higher capacity as compared to the standard NiCd.
  • Less sensitive to the memory effect than the NiCd.
  • Simple storage and transport – transport conditions are not subject to legal audit.
  • Environment-friendly – only contains mild toxic substances.
  • Profitable for recycling.


Disadvantages of nickel metal hydride batteries

  • Limited lifespan – if repeatedly deeply discharged, performance deteriorates after 200 to 300 cycles.
  • Limited discharge current – although a nickel metal hydride battery is capable of delivering high discharge currents, repeated discharge with high load currents reduces the battery’s life.
  • Complex charging algorithm required.
  • More heat during charging and a longer charging time than the NiCd.
  • High maintenance – battery requires regular full discharge to prevent crystalline formation.
  • About 20% more expensive than NiCd.

Comparison with Li-ion

Nickel-metal hydride batteries have some disadvantages compared to lithium-ion batteries. For instance, NiMH batteries need to be discharged once every two months, while this is not necessary for Li-ion batteries.


Additionally, Li-ion batteries require no maintenance, have no memory effect, experience less self-discharge, and are slightly more compact due to their higher energy density. These batteries also have a lifespan of approximately 500 cycles. It’s important to note that Li-ion batteries are more sensitive to heat.


We would like to advise you on making the right battery choice. We have the knowledge and experience for this in-house.
