What types of batteries do radio control vehicles use?

There are a few common types of radio control batteries:

Zinc-carbon This is the technology of inexpensive dry cell, non-rechargeable batteries such as AA, AAA, C, and D. Zinc and carbon serve as the electrodes while an acidic paste serves as the electrolyte.

Alkaline This is the technology of the more expensive dry cell, non-rechargeable batteries. Duracell and Energizer are two of the most popular manufacturers of alkaline batteries. These batteries have zinc and manganese-oxide as their electrodes and an alkaline compound as the electrolyte.

NiCd Nickel Cadmium radio control batteries are rechargeable with nickel-hydroxide and cadmium electrodes and potassium hydroxide as the electrolyte.

NiMH Nickel-metal hydride batteries are also rechargeable. They have a nickel hydrogen and a hydrogen absorbing alloy as the electrodes and potassium-hydroxide as the electrolyte.

Lithium polymer These have lithium nickel cobalt oxide-based and carbon based electrodes with a polymer biphasic electrolyte. (Say that ten times quickly!)
