Definition of NiCad in US English:


(also Nicad)


  • A battery or cell with a nickel anode, a cadmium cathode, and a potassium hydroxide electrolyte. NiCads are used chiefly as a rechargeable power source for portable equipment.

    ‘NiCad batteries’
    • ‘The battery is a NiCad pack that takes between 12 and 14 hours to fully recharge and provides around two hours on full power and five hours when using the 12Watt head alone.’
    • ‘A NiMH battery stores more of the chemicals and materials that generate direct current, so it produces more amp hours than a NiCad pack of equivalent volume does.’
    • ‘I know that spinning a physical disk draws a lot more charge out of a NiCad or Alkaline cell than just pushing electrons around inside a semiconductor chip.’
    • ‘The unit is powered by a snap-on battery pack containing either a Litium battery or a Nicad rechargeable battery.’
    • ‘When you recharge a NiCad battery before it is completely drained, the longevity of the battery is compromised.’
