Ni–Cd cells are available in the same sizes as alkaline batteries, from AAA through D, as well as several multi-cell sizes, including the equivalent of a 9 volt battery. A fully charged single Ni-Cd cell, under no load, carries a potential difference of between 1.25 and 1.35 volts, which stays relatively constant as the battery is discharged. Since an alkaline battery near fully discharged may see its voltage drop to as low as 0.9 volts, Ni-Cd cells and alkaline cells are typically interchangeable for most applications.
Widely used in radio controlled devices, electric tools and toys, electric mopeds, meters, two radios, hybrid automobiles, electric razors, toothbrushes, cameras, camcorders, mobile phones, pagers, medical instruments/equipment, high power static applications (Telecoms, UPS and Smart grid), and numerous other applications.
Hight capacity, better power performance, lower internal impedance, more stable performance, safer and more reliable, better storage performance.
For a common AA-size cell, the maximum discharge rate is approximately 1.8 amperes; for a D size battery the discharge rate can be as high as 3.5 amperes
Provides long use time per charge with this very high capacity
Designed for enhanced performance for high drain applications such as emergency lighting, portable devices, power tools
