NiMH battery and accumulator (Nickel Metal Hydride)

NiMH batteries are a newer technology than Ni-Cd that offer higher energy densities than Ni-Cd. NiMH supplies about twice the capacity of tis Ni-Cd counterpart. This translates into an increased runtime of the battery.

Little maintenance

A nickel metal hydride battery (NiMH) also offers another major advantage: Ni-Cd batteries tend to suffer from the so-called ‘memory effect’. NiMH batteries are less likely to develop this troublesome limitation and therefore require less maintenance and care. They have a wide temperature durability as well as a higher capacity than Ni-Cd batteries. NiMH batteries are also more environmentally friendly than their Ni-Cd counterparts because they contain no heavy metals.

NiMH battery examples

Elfa has many different batteries in its range that may be of interest to you. For example, Energizer has several options, such as the Energizer Recharge NiMH batt C HR14 2500mAh. This battery from Energizer has a high capacity and has almost no memory effect. Energizer is a well known name in the field of quality batteries. View the entire Energizer assortment here.

Tailor-made pack assembly

Panasonic’s NiMH battery is also available as a battery pack made to measure. In our own assembly department we produce battery packs and accumulator packs that meet specific customer requirements. Dimensions, voltage, capacity, connector and seal are made according to your wishes and requirements.

Advantages of nickel metal hydride batteries

30-40% higher capacity as compared to the standard Ni-Cd.
Less sensitive to the memory effect than the Ni-Cd.
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 Ni-Cd.
High maintenance – battery requires regular full discharge to prevent crystalline formation.
About 20% more expensive than Ni-Cd.
