Lithium 6V CR-P2 Battery

CR-P2 battery is a rather popular camera battery with terminals on one end and with the battery dimensions of (H x L x W) of 36 x 35 x 19.5 mm.

CR-P2 battery design ensures that it can be inserted in the battery compartment in only one way, preventing accidental damage to the equipment powered by this battery.

The standard label of this battery is CR-P2 battery, but other labels are used as well, including BR-P2, 5024LC, 223A, EL223AP, K223LA, CR17-33, etc. But, practically all manufacturers state 'CR-P2' as part of their label.

Internally, the CR-P2 battery features two lithium 3V cells connected in series. Thus, the nominal voltage of the CR-P2 battery is 6 volts, and the cutoff voltage around 4.0 volts, although actual capacity also depends on the cutoff voltage of the device being powered by this battery.

The nominal capacity of the CR-P2 battery varies between 1300 and 1700 mAh - larger capacity is not always a good indicator if the battery is a good choice for high drain devices.

CR-P2 battery features lithium non-rechargeable chemistry - lithium is used as anode (negative electrode) while manganese dioxide is used as the cathode (positive electrode) with organic electrolyte between anode and cathode.

Although modern CR-P2 batteries don't contain mercury, cadmium, or other heavy metals, or similar pollutants, they should be disposed of properly.

Shelf life of non-rechargeable lithium batteries, CR-P2 battery included, varies, but commonly it is in the 7-10+ years range, allowing the devices to be used at the moment notice, even if they weren't used for a very long time.

Due to its shape and dimensions (H x L x W - 36 x 35 x 19.5 mm), CR-P2 battery is roughly double the size of the single CR123A battery (H x D, 34.5 x 17 mm), or its dimensions are very close to the two CR123A batteries side-by-side (H x L x W): 34.5 x 34 x 17 mm vs 36 x 35 x 19.5 mm.

Some devices feature battery compartments designed to accept both types of batteries allowing the use of either CR-P2 or two CR123A batteries, simplifying battery management.

Note: While the CR-P2 battery can't be inserted in the wrong way in its battery compartment, CR123A can so be careful when replacing the CR-P2 battery with a pair of CR123A batteries.

Since some devices that use CR123A (non-rechargeable lithium 3.0 volts) battery allow the use of RCR123A (rechargeable lithium battery with voltages in 3.0-3.2 and 3.6-3.7 volts, depending on the exact chemistry type), devices that allow the use of either CR-P2 or two CR123A batteries should NOT use RCR123A batteries, especially not RCR123A batteries with nominal voltage in the 3.6-3.7 volts range unless explicitly stated by the device's manufacturer that the use of RCR123A batteries of that voltage is allowed in those devices.

Long Story Short: CR-P2 battery powers a large number of photo and video cameras and is manufactured by all most important battery brands and is relatively easy to purchase at local hardware stores or online shops.

If your device supports the use of CR123A batteries, one CR-P2 battery may be replaced by a pair of CR123A batteries, just be careful about the orientation of these batteries.
