What is nickel cadmium used for?
A nickel-cadmium battery (NiCd or NiCad) is a rechargeable battery used for portable computers, drills, camcorders and other small battery-operated devices requiring an even power discharge. NiCds use electrodes made of nickel oxide hydroxide, metallic cadmium and an alkaline electrolyte of potassium hydroxide.
Are NiCd batteries still made?
Ni-Cd batteries are made in a wide range of sizes and capacities, from portable sealed types interchangeable with carbon-zinc dry cells, to large ventilated cells used for standby power and motive power….Nickel–cadmium battery.
| From top to bottom: "Gumstick", AA, and AAA Ni–Cd batteries | |
|---|---|
| Specific energy | 40–60 W·h/kg |

Can I replace a NiCd battery with a NiMH?
Many people have asked “can I use NiMH (Nickel Metal Hydride) batteries in my solar lights that have NiCd (Nickel Cadmium)?” And the answer is, yes! Not only can you replace with NiMH, but they are the better choice of battery as they have benefits that their NiCd counterparts don't.
Which is better NiCd or NiMH?
One of the most noticeable improvements is that the NiMH is far better for the environment. The biggest advantage of all, however, is that their capacity is often 2 or 3 times better than a regular NiCD battery, due to their superior energy density.
Is NiCad better than lithium?
Lithium-ion batteries are smaller in size, require less maintenance and are environmentally safer than Nickel-cadmium (NiCad) batteries. While they have similarities, Li-ion and NiCd batteries differ in their chemical composition, environmental impact, applications and costs.
