CR-V3 battery

CR-V3 battery

A CR-V3 battery (sometimes CRV3) is a type of high-capacity battery used in various electronic appliances, including many digital cameras. It has the shape and size of two side-by-side AA batteries. This allows CR-V3 batteries to function in many cameras and other devices originally designed only for AA batteries.

Often, CR-V3 batteries are based on a non-rechargeable lithium battery chemistry, with a nominal voltage of 3 V (the same as 2 alkaline AA batteries). Rechargeable lithium-ion RCR-V3 batteries, with a nominal voltage of 3.7 V, are also available. Because both lithium and lithium-ion chemistries offer higher energy density than alkaline batteries or even NiMH rechargeable batteries, a CR-V3 battery will typically last much longer than a pair of AA batteries.

Some non-rechargeable CR-V3 batteries are made of two AA-sized batteries soldered together inside a plastic shell. These can be broken apart and installed in cameras with battery compartments that cannot accommodate CR-V3 batteries. However, many cameras not explicitly designed for use with CR-V3 batteries can in fact accept them.

Explains how to determine if CR-V3 batteries will fit in a digital camera, and concludes that they offer longer battery life and better value than NiMH rechargeable batteries.
