What does CR stand for in battery types?
I just got a new torch which uses CR123a lithium batteries, but what does “CR” stand for?
*CR123A Lithium Batteries:
The cylindrical lithium manganese dioxide battery (CR battery) features high capacity and excellent load characteristics due to Maxell’s unique winding method and improved electrical-conductivity structures. Because of its high-reliability, this battery is ideal for industrial use in, for example, security equipment and the power source of electronic meters.

*Different types of batteries use different types of chemicals and chemical reactions. Some of the more common types of batteries are:
Alkaline battery — Used in Duracell¨ and Energizer¨ and other alkaline batteries. The electrodes are zinc and manganese-oxide. The electrolyte is an alkaline paste.
Lead-acid battery — These are used in automobiles. The electrodes are made of lead and lead-oxide with a strong acid as the electrolyte.
Lithium battery — These batteries are used in cameras for the flash bulb. They are made with lithium, lithium-iodide and lead-iodide. They can supply surges of electricity for the flash.
Lithium-ion battery — These batteries are found in laptop computers, cell phones and other high-use portable equipment.
Nickel-cadmium or NiCad battery — The electrodes are nickel-hydroxide and cadmium. The electrolyte is potassium-hydroxide.
Zinc-carbon battery or standard carbon battery — Zinc and carbon are used in all regular or standard AA, C and D dry-cell batteries. The electrodes are made of zinc and carbon, with a paste of acidic materials between them serving as the electrolyte.
