• The nickel-cadmium battery (commonly abbreviated NiCd or NiCad) is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes.

• The abbreviation NiCd is derived from the chemical symbols of nickel (Ni) and cadmium (Cd) .

CharacteristicCharacteristic

• available in the same sizes as alkaline batteries, from AAA through D.

• the maximum discharge rate for a

NiCd battery varies by size.

• For a common AA-size cell, the maximum discharge rate is approximately 18 amps.

• For a D size battery the discharge rate can be as high as 35 amps.
