Nickel Cadmium Battery (Nicad) – a rechargeable battery that uses metallic cadmium and nickel oxide hydroxide as electrodes. Nicad Cadmium batteries are available in standard cylindrical sizes such as AA, AAA, C, etc..
Benefits of a Nicad Cadmium Battery:
- More energy density than a sealed lead acid battery.
- Nicads have built-in chemical protection against polarity reversal or over discharge.
- Nicads have built-in resealable safety vents to alleviate internal pressure in case of possible abuses.
- Nickel Cadmium batteries can be easily assembled to get to a necessary voltage and milli-amperage in multiple different configurations to fit inside of a product.
