NiCd batteries

Batteries which can be recharged are known as accumulators. An ensemble of accumulators is called a battery pack. NiCd is formed by a positive steel-plated electrode covered in cadmium, a negative electrode made up of sintered nickel foil filled with nickel hydroxide and the electrolyte is made up of an aqueous solution of potassium. NiCd accumulators have a spiral-wound structure with a safety vent.
It can be used for power tools, emergency lighting packs (applications which are permanently on charge), measuring and security devices, home automation, electronic money products, robotics, IT, industrial watchmaking, medical equipment, etc.

Its capacity varies very little according to rate of discharge and it is rugged with low impact sensitivity. However, NiCd has a low energy density and its rate of self-discharge is 8% per month. Its nominal voltage is 1.2V and goes up to 1.4V when fully charged. Its cut-off voltage is 1V. It can supply up to 500 charge and discharge cycles. Its working temperature ranges between -40°C and 60°C. It can be stored for up to two years between -20°C and 35°C.
