A CR-V3 battery (sometimes CRV3) is a type of disposable high-capacity 3-Volt battery used in various electronic appliances, including some digital cameras. It has the shape and size of two side-by-side AA batteries[1]. This allows CR-V3 batteries to function in many (though not all) devices originally designed only for AA batteries. An RCR-V3 battery is a rechargeable 3.7 V lithium-ion battery.
[edit] Disposable CR-V3 batteries
Often, a CR-V3 battery is a single cell 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 is designed to last much longer than a pair of AA batteries.

[edit] Rechargeable RCR-V3 batteries
Rechargeable lithium-ion RCR-V3 batteries, with a nominal voltage of 3.7 V, are also available.
