• 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.
