Nickel-Cadmium

Nickel-Cadmium (NiCd) and Nickel-Metall-Hydrid (NiMH) are similar types of technology which can replace each other in various applications.

Advantages

Disadvantages

+ high amount of charge and discharge cycles (up to 1,000)

- low energy density

+ long shelf life (up to five years)

- monthly care helps to avoid the memory effect

+ good cost-performance ratio
+ out-performances other technologies at lower temperatures

- oxic cadmium is environmentally unfriendly and forbidden in some countries like the Scandinavians
