Ni-cad batteries first became popular as portable rechargeable batteries.
The "regular batteries" used in cars are mostly lead-acid rechargeable batteries.
The "regular batteries" used in toys, remote controls, flashlights and such, are mostly the non-rechargeable types.
Ni-cad batteries use nickel and cadmium. The latter is a toxic substance, difficult to dispose of, and ni-cad batteries have a nasty tendency to lose capacity (the "memory" effect).
For that and other reasons, makers of lightweight rechargeable batteries have switched to using nickel-metal-hydride or lithium batteries.
(Lithium-metal = explosive, lithium-ion = very popular, lithium-polymer = extremely lightweight, lithium-iron-phosphate = next generation for hybrid and electric cars.)
The Prius Hybrid uses nickel-metal-hydride battery cells.
When weight or size is not as much of a concern, lead-acid batteries are used due to their lower cost. Most automobiles and many industrial uninterruptable power supplies use lead-acid batteries, which are capable of providing several hundred amperes of current for a short time.
Ni-cad batteries are rechargeable, regular are not rechargeable.

What is the difference between NiCad and NiMH batteries?
NiCad batteries use nickel and cadmium, while NiMH batteries use nickel and metal hydride. NiMH batteries have higher energy density and are more environmentally friendly than NiCad batteries.
What element is used to make nicad rechargable batteries?
Nicad is short for nickel-cadmium
What word is blend of the words nickel and cadmium?
That is nicad, pertaining to batteries.
Do increases or decreases in temperature affect Nicad batteries?
Yes,
What is the output voltage of a typical size D NiCad cell?
Typical D cell batteries NiCad or otherwise are 1.2 volts.
What is used to neutralize a spill of NiCad battery electrolyte?
Nicad batteries have sodium hydroxide electrolyte. Citric acid powder will neutralize it.
Elements used with nickel to make nicad batteries?
NiCd Nickel & Cadmium
How do you rejuvenate power tool nicad batteries?
You cannot do that. When dead, they are gone for good.
Flashlight that docks in a charger to recharge two AA nickel cadmium batteries so can an you replace these batteries with cadmium metal hydride ones?
No, you should not replace nickel cadmium batteries with nickel metal hydride batteries interchangeably in a device designed for nickel cadmium batteries. They have different charging requirements and using the wrong type can damage the device. It is important to follow the manufacturer's recommendations for battery type.
Are watch batteries different from regular batteries?
yes watch batteries are different from regular batteries because watch batteries are much smaller and hold less electrical charge. they would not work in anything else other than a watch.
What is the difference between a NiCad battery and a NiMH battery?
In NiCad batteries the negative electrode is made of Cadmium, while in NiMH batteries it is made of an intermetallic compund, consisting of a rare earth (such as Lanthanum or Cerium) and a transition metal (such as Manganese or Nickel). anonymous@oola.com
Why do some instructions say use alkaline batteries only?
The different chemistries makes a different voltage. The alkaline is 1.5 volts and the NiCad is 1.2 when fully charged. If it will work with the lower voltage then it may only assume that the battery is low. But when the NiCad actually gets low then the device may not work properly.
