Lithium CR-V3 3V Battery
Lithium CR-V3 3V battery is a high-drain, high-capacity, rectangular battery, commonly used in cameras and other similar electronic devices that require a lightweight, but strong source of power.
Lithium CR-V3 3V battery is manufactured by most battery brands and can be easily purchased in stores and online shops. However, various manufacturers use different labels and sometimes even chemistries, leading to certain confusion among users.

Lithium CR-V3 Battery Features and Specifications
CR-V3 battery features physical dimensions of (H x L x W) 52.20 x 28.05 x 14.15 mm (~2.055 x 1.104 x 0.557 inches). Also, the CR-V3 battery is shaped so it can be inserted into the battery compartment only one way, preventing the users from inserting the battery the wrong way.
Battery terminals are on one end only.
Most common label of lithium 3.0V non-rechargeable 52.20 x 28.05 x 14.15 mm (~2.055 x 1.104 x 0.557 inches) battery is CR-V3, although other labels are used as well, including CRV3, 5047LC, 5047LF, ECR-V3, RCR-V3, etc.
Non-Rechargeable CR-V3 vs. Rechargeable CR-V3 Battery
Non-rechargeable CR-V3 batteries feature a nominal voltage of 3.0 volts, a cutoff voltage of 2.0 volts, and a nominal capacity in the 3000-3300 mAh range.
Nominal capacity depends on the battery age, local temperature, discharge conditions, and similar.
Since CR-V3 batteries are intended for powering high-drain devices, both their capacities and pulse discharge characteristics are important when determining the quality of the battery.
Lithium non-rechargeable CR-V3 batteries can provide currents up to 2 Amps continuously and up to 3.5-4 Amps for shorter periods of time.
Rechargeable CR-V3 batteries are very often labeled RCR-V3 batteries. They feature nominal voltage in the 3.0-3.7 volts range and a nominal capacity of around 2000-2100 mAh.
Although they feature a smaller capacity than non-rechargeable CR-V3 batteries, rechargeable CR-V3 batteries can be recharged hundreds of times, saving plenty of money.
And to make things even better, their chargers very often support connections to USB ports, 12V cigarette car lighter ports, or 110/220 wall sockets.
On the other hand, there may be a small issue with a nominal voltage.
Rechargeable CR-V3 batteries with a nominal voltage of 3.0 volts are directly compatible with non-rechargeable CR-V3 3.0 volts batteries.
However, rechargeable CR-V3 batteries with a nominal voltage of 3.6-3.7 volts can be used to replace non-rechargeable 3.0 volts CR-V3 batteries only if the device in question supports the use of both 3.0 and 3.6-3.7 volts batteries - it must be clearly stated by the manufacturer of the device.
A voltage difference of 0.6-0.7 volts doesn't sound much, but it can damage or even destroy sensitive electronics - not often, but often enough to be careful ...
CR-V3 Battery vs. AA Battery
Physically, the CR-V3 battery looks very similar to a pair of AA batteries placed side-by-side. Their physical dimensions are:
- CR-V3 battery: 52.20 x 28.05 x 14.15 mm (~2.055 x 1.104 x 0.557 inches),
- AA battery: 50.5 x 14.5 mm (~1.988 x 0.571 inches).
This allows most CR-V3 battery compartments to accept two AA batteries instead of one CR-V3 battery; just be sure that the bottom of the battery compartment has an additional connection between the bottom of the AA batteries - such connection is not required for CR-V3 batteries, and some devices simply lack additional connection required by AA batteries.
Since alkaline AA batteries feature a nominal voltage of 1.5 volts, a pair of AA batteries connected in series feature 3.0 volts, which is exactly the voltage of a new, fresh CR-V3 battery.
CR-V3 Battery Comparison Chart
The following comparison chart lists some of the most popular CR-V3 batteries and their most important features and specifications:
|Model||Capacity||Operating Temperature||Discharge Current|
|Duracell CR-V3||-||-20°C to +60°C||1.2A, 3s On, 7s Off, down to 1.7V @20°C: ~2700 cycles
1.8A, 3s On, 7s Off, down to 2.0V @20°C: ~1600 cycles
|Energizer ELCRV3||3000 mAh over 100Ω, down to 2.0V @21°C||-40°C to +60°C||1000 mA for 2.8h down to 1.8V @20°C|
|Panasonic CR-V3||3000 mAh||-40°C to +70°C||2A max. cont. 3.5A max. pulse|
As one can see, CR-V3 batteries are intended for high-drain photo cameras and video equipment and are designed to provide strong continuous currents or very strong repetitive pulses.
Of course, there are other CR-V3 brands on the market, not just those shown in the chart.
Long Story Short: If your camera requires 3.0 volts CR-V3 battery, go for either a 3.0V non-rechargeable or 3.0V rechargeable CR-V3 battery.
If your device supports the use of both 3.0V and 3.6-3.7V batteries, feel free to go for a 3.0V non-rechargeable, 3.0V rechargeable, or 3.6-3.7V rechargeable CR-V3 battery.
