CR-P2, BR-P2, 5024LC, 223A, CR17-33 Battery Equivalents and Replacements
CR-P2, BR-P2, 5024LC, 223A, CR17-33 batteries are very popular non-rechargeable lithium batteries, commonly used in photo and film cameras, medical systems, security systems, standby devices and other applications where reliable and strong source or energy is required, even after a long time of being stored away.
CR-P2, BR-P2, 5024LC, 223A, CR17-33 are made by practically all most reputable battery brands and can be easily found at most hardware and online shops. But, since manufacturers use several, often non-standardized labels, to describe these batteries, some confusion may arise ...

CR-P2 Features and Specifications
CR-P2 is a rectangular lithium battery with physical dimensions of (H x L x W) 36 x 35 x 19.5 mm. It features two lithium cells connected in series with a nominal voltage of 6.0 volts and a cut-off voltage of 4.0 volts, although actual cut-off voltage depends on the device being powered by this battery.
Nominal capacity is in the 1300-1500 mAh range, but it depends on the discharge current and the actual cut-off voltage.
But, since CR-P2 batteries are lithium batteries, their main task is providing energy for high-current devices, including photographic equipment.
One of the very interesting features of CR-P2 battery is its shape - CR-P2 battery is shaped so that it can fit the battery compartment only one way, allowing the user to quickly replace the empty battery with a new one even in low light and similar stressful conditions.
The most common label for this battery is "CR-P2 battery" although other labels are used as well, for example: BR-P2, 5024LC, 223, 223A, CR17-33, 6204, etc.
Thanks to lithium chemistry, CR-P2 battery commonly has shelf/standby life of 7-10 years, with some models featuring shelf life of even longer.
Also, CR-P2 batteries often have a very broad range of operating temperatures, often from -40°F to 140°F (-40°C to 60°C), although this parameter is model/brand dependent.
CR-P2 vs CR123A Battery
With its dimensions of (H x L x W) 36 x 35 x 19.5 mm, CR-P2 battery looks very similar to two CR123A (H x D: 34.5 x 17.0 mm) batteries side by side.
Technically, many manufacturers use their CR123A cells to make CR-P2 batteries by placing CR123A batteries in a suitable battery package.
Also, some devices designed to accept one CR-P2 battery feature a battery holder for a pair of CR123A batteries, allowing the user to power the device with multiple batteries.
Note: When placing two CR123A batteries in such battery holder, be very careful regarding their orientation.
However, the use of rechargeable CR123A batteries, often labeled as RCR123A batteries, is not recommended unless explicitly allowed by the manufacturer of such a device.
The actual problem are not dimensions, but voltages - CR-P2 battery features a nominal voltage of 6.0 volts, while two RCR123A batteries connected in series feature nominal voltage of 7.2-7.4 volts.
Such voltage difference doesn't sound large, but it can damage or even destroy sensitive electronic equipment, or at least cause them to malfunction.
For short, when replacing 6.0 volts CR-P2 battery with CR123A batteries, use non-rechargeable 3.0 volts CR123A batteries.
Long Story Short: CR-P2, BR-P2, 5024LC, 223, 223A, CR17-33, 6204, etc. batteries are non-rechargeable, 6.0 volts lithium batteries. When looking for a replacement, go for reputable brands, especially if you need the battery that features long shelf life.
While some devices come with 2xCR123A battery holder that may replace one CR-P2 battery, be sure to use only non-rechargeable 3.0 volts CR123A batteries, unless stated by the manufacturer of the device that that device supports the use of 2xRCR123A (again: 7.2-7.4 volts nominal voltage) batteries.
