Standard Cylindrical Batteries
Standard cylindrical batteries are broad category of batteries regarding their sizes, chemistries, features etc.
These batteries are widely used for powering all source of devices, toys, instruments etc. and getting the right ones sometimes may be little bit confusing.
We have grouped standard cylindrical batteries into two charts: the most common small cylindrical batteries (like AAA, AA, C etc.) and cylindrical lithium non-rechargeable and rechargeable batteries (like CR123A, 18650 and similar).
Here is the cross reference chart of the most common small cylindrical batteries:

Best Non-Rechargeable and Rechargeable CR123A Batteries
Lithium 3.0 volts non-rechargeable CR123A batteries are one of the most popular cylindrical battery sizes in the world, used for powering all sorts of devices including LED flashlights, cameras, medical and security devices, toys, remote controllers, etc.
CR123A batteries feature long shelf-life, can provide strong drain currents, have stable output voltage, etc., but they are non-rechargeable batteries. Rechargeable CR123A batteries, often labeled as RCR123A, can be recharged several hundred times, but have somewhat larger voltage and smaller capacity and can't replace CR123A batteries in all devices.
