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.
