Kerosene was a common fuel used in torches before batteries.
Primary cells are designed to be used once and discarded. Secondary cells are, by definition, rechargeable batteries, and as such are the kind used in rechargeable torches (or flashlights, for you American types).
A common fuel used in torches is propane gas. It burns cleanly and produces a steady flame, making it suitable for various outdoor and DIY projects.

Scientists developed torches by combining a fuel source, such as oil or wax, with a flame-producing mechanism, such as a wick. Early torches likely evolved from natural materials like wood sticks or plant fibers soaked in flammable substances, eventually leading to more controlled, portable torch designs for illumination purposes.
There are different sizes of batteries available to buy and they are have various alphabetical letters to categorize them. For example the "D" battery is normally used for things like huge torches as this size and type of battery is used for portable items that need extended battery life to operate them efficiently.
Yes, there are a variety of torches, from wicker outdoor Tiki torches that normally burn citronella oil to ward of insects, to acetylene torches used for cutting metal.
