CR2 Photo Lithium Batteries are commonly used in today’s Digital Cameras, LED flashlights, Light Meters and other Photographic Equipment.

CR2 lithium batteries are 3 volt, single-use batteries. Single-use simply means they are not rechargeable as Lithium Ion chemistry batteries are. Another term used to describe non rechargeable batteries is, disposable.

An advantage of CR2 lithiums is their excellent shelf life, at 10 years on average. If you use them, you should stock up for future use when you spot a great deal! They offer Ultra high energy density and can last  between 3 and 5 times longer than ordinary alkaline batteries.
