NiCd Rechargeable Battery FAQs and Information
Some say the NiCd Rechargeable Battery is obsolete due to its lower
capacity and disposal requirements. The NiCd Battery technology still
outperforms other technologies when it comes to high drain regular use
applications.

The Nickel-Cadmium Battery
- Invented in 1899 by Swedish inventor Waldmar Jungner.
- In 1899 its use was limited to special applications due to cost compared to other batteries.
- In 1932, the active materials were deposited inside a porous nickel-plated electrode.
- In 1947 research began on a sealed nickel-cadmium battery.
- Rather than venting, the internal gases generated during charge were recombined. These advances led to the modern sealed nickel-cadmium battery, which is in use today.
- the NiCd battery prefers fast charge to slow charge and pulse charge to DC charge.
- the NiCd battery is the only battery type that performs well under rough working conditions.
- All other chemistries prefer a shallow discharge and moderate load currents.
- Ni-Cd does not like to be pampered by sitting in chargers for days and being used only occasionally for brief periods.
- A periodic full discharge is important.
- Omission of periodic full discharge forms large crystals on the cell plates (also called memory).
- The Nickel-Cadmium battery will gradually lose its abilities.
- Among rechargeable batteries, Ni-Cd remains a popular choice for high drain regular use devices such as two-way radios, emergency medical equipment and power tools.
- Ni-CD batteries are durable and low cost.
