A CR-V3 battery (sometimes CRV3) is a type of disposable high-capacity 3 V 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. An RCR-V3 battery is a rechargeable 3.7 V lithium-ion battery.

Disposable CR-V3 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). 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.[citation needed]
Rechargeable RCR-V3 batteries
Rechargeable lithium-ion RCR-V3 batteries, with a nominal voltage of 3.7 V, are also available. A review by Andrzej Wrotniak concluded that "1700 mAh NiMH's easily outperformed [1200 mAh RCR-V3's]" in tests using two digital cameras.[1]
