The first nickel-cadmium battery was invented by Waldmar Jungner in 1899. At that time, lead-acid was the only direct competitor that was physically and chemically robust. Jungner offered several advantages over the lead-acid battery, but the materials were expensive and use was limited. In 1932, active materials were deposited in a porous, nickel-plated electrode. And after 14 years, the first production in the US began in 1946.
Because the battery is robust and can be charged ultra-fast with little stress, this chemistry soon gained a high popularity and the battery is still used for its good charging performance; the long shelf life (can be stored in a discharged state) and simple storage and transport.
The battery gives good performance at low temperatures and is economically priced. This means that NiCD often has the lowest price in terms of costs per cycle. The battery is available in a wide range of sizes and performance options. At Elfa, we can, in fact, make custom battery packs from NiCd batteries.
Standard NiCd needs proper care to achieve a long life. nickel-cadmium batteries can have a “memory effect” when discharged and charged hundreds of times to the same state of charge. The battery seems to remember the previous energy delivered and once a routine is established, it doesn’t want to give anymore.
As of January 1, 2017, the sale of Nkkel cadmium batteries for small appliances, such as portable power tools, is no longer allowed in Europe. The special exemption issued for this purpose expired on 31 December 2016. The reason why NiCd batteries have been banned for consumer use is because they contain the highly toxic cadmium and therefore the batteries are very harmful to the environment. It is therefore very important that these batteries are recycled properly. NiCd batteries used for the applications listed below fall outside this regulation and may still be sold:

This battery pack is characterized by its compactness and robustness. The new strategy of Arts Energy is marked by their offering of various technologies, the connectivity of their products, and customized solutions, which is central to their approach.
As mentioned earlier, NiCd batteries also have some drawbacks. Disadvantages of NiCd batteries include relatively low specific energy, the memory effect requiring periodic full discharges, the toxic nature of cadmium, and high self-discharge.
An interesting alternative is NiMH batteries. NiMH batteries, for example, have a 30-40% higher capacity than NiCd batteries. They also suffer significantly less from the memory effect and are more environmentally friendly as they do not use toxic materials. Finally, NiMH batteries experience less self-discharge than NiCd batteries.
At Elfa, we also have NiMH batteries from various brands, such as the rechargeable NiMH batteries from Varta, with a voltage of 1.2V and a capacity of 3Ah. These are known for their efficiency, durability, and high-quality materials. The Varta brand is based in Germany and is globally recognized as one of the top battery manufacturers.
However, NiMH batteries also have a disadvantage. They are unsuitable for use in environments and countries with extreme heat or cold. Therefore, it is preferable to store these batteries in a cool ambient temperature (>1 and < 25 degrees Celsius). The battery loses its charge at low temperatures, and at high temperatures, the battery may become damaged.
