It's a battery that uses nickel oxide in its positive electrode (cathode), a cadmium compound in its negative electrode (anode), and potassium hydroxide solution in its electrolyte. The Nickel Cadmium Battery is rechargeable, so you can use it over and over.

Battery features
- General-use batteries (Standard series)
High performance and reliability.
- High-capacity batteries (E / U series)
High density electrode plate and new design provide 40-100% higher capacity than conventional batteries.
- Quick-charge batteries (R / CP series)
Improved gas circulation during charging and discharging enables quick charging in only one hour.
- High-temperature batteries (H series)
Charge effectiveness, discharge capacity, and service life are greatly increased. Trickle charging ability in high temperatures is also greatly improved.
- Heat-resistant batteries (K series)
Heat-resistant design makes it possible to quick-charge in temperatures up to 70.
- Long life(C / EC series)
Use of a new separator provides superior performance in continuous charge and cycle modes. Longer service life than conventional batteries.
- Memory-backup batteries(S series)
With extremely low self-discharge during storage, memory can be preserved for a long time.
