Lithium CR-V3 3V Battery
Lithium CR-V3 battery is a 3V non-rechargeable battery, often used in photo equipment and other devices that require the battery being able to provide plenty of power in short bursts.
Also, thank to its shape, the CR-V3 battery cannot be inserted the wrong way, helping the user replace the battery even in low light conditions safely.
CR-V3 Battery Dimensions, Features, and Specifications
CR-V3 battery is a flat, rectangular featuring physical dimensions of (H x L x W) 52.20 x 28.05 x 14.15 mm, with both battery terminals on one end of the battery.
Non-rechargeable CR-V3 battery features lithium-manganese chemistry, nominal voltage of 3 volts, cutoff voltage of 2.0 volts, and nominal capacity of ~3000 mAh.
Some manufacturers claim even larger capacity, but actual capacity depends on the device being used and drain currents.
Thanks to the very low self-discharge rate of lithium chemistry, CR-V3 batteries often feature a shelf-life of 7-10 years, sometimes even more.
As such, CR-V3 batteries are sometimes used even in the certain EDC devices that must operate at the moment notice after years of not being used.
CR-V3 batteries are very popular batteries and are manufactured by practically all the most reputable battery brands and are available at most online shops and hardware stores.
Note: CR-V3 batteries are also sometimes labeled as CR-V3, 5047LC, 5047LF, CRV3, RCR-V3, etc.
CR-V3 vs RCR-V3 Battery
Lithium CR-V3 battery features a nominal voltage of 3.0 volts and it is a non-rechargeable battery.
Lithium RCR-V3 is a 'rechargeable CR-V3' battery (hence 'RCR-V3' label), with nominal voltage and capacity depending on the actual chemistry being used - nominal voltage varies between 3.0-3.2 and 3.6-3.7 volts.
Due to the slight difference in voltage, not all devices can accept RCR-V3 battery instead of CR-V3 battery, except 3.0 volts RCR-V3 batteries.
Note: most modern devices are designed to accept input voltages between 3.0 and 3.7 volts, but before replacing your CR-V3 3.0 volts battery with an RCR-V3 battery, check the device's Owners Guide/Manual, if that device can accept an RCR-V3 battery.
RCR-V3 batteries feature a nominal capacity of 1300-2200 mAh, although nominal capacity (again) depends on the drain current and similar.
Although RCR-V3 batteries feature lower capacity than CR-V3 batteries, they can be recharged hundreds of times.
Note: when charging RCR-V3 batteries, always use the battery charger provided or recommended by the battery manufacturer. Never use other battery chargers.
CR-V3 vs AA Battery
CR-V3 is a flat, rectangular battery, while AA battery is a cylindrical battery - at first, these two batteries don't have much in common. But, their physical dimensions are:
- CR-V3 battery (H x L x W): 52.20 x 28.05 x 14.15 mm,
- AA battery (H x D): 50.5 x 14.5 mm.
As one can see, CR-V3 battery dimensions are very similar to the dimensions of two AA batteries side-by-side.
In fact, many cameras and similar devices feature battery compartments design to accept either 2xAA or CR-V3 batteries, giving the users extra freedom when choosing the batteries.
However, lithium CR-V3 batteries store more energy than a pair of AA batteries and are the preferred choice over AA batteries.
Long Story Short: CR-V3 battery stores plenty of energy in a compact and lightweight package and release it when required, even years after not being used.
If You are looking for a new CR-V3 battery, always go for the battery manufactured by some of the most reputable brands, tried and tested by many users in real-life situations.
