CR-P2 Battery Equivalents and Replacements

CR-P2 is a very popular non-rechargeable 6V battery, commonly used in photo equipment, but also for powering other electronic devices that require a stable power source able to provide strong currents even after long periods of time being stored away.

CR-P2 battery is the most common label, but other labels are used as well, including BR-P2 battery, 5024LC battery, 223A battery, CR17-33 battery, etc. Fortunately, in order to avoid confusion, most brands use CR-P2 and 223A labels practically always.

CR-P2 Battery Features and Specifications

CR-P2 battery features physical dimensions of (H x L x W) 36 x 35 x 19.5 mm and a weight of 35-38 grams. The battery is shaped so that it can be inserted into a battery compartment only one, proper way. This allows the user to replace the battery even in low-light and other difficult conditions.

Both battery terminals are on one side, with a standard terminal diameter of 8.7 mm - when the battery is positioned vertically, with the flat surface toward the user, the positive port is to the left.

The nominal voltage of the CR-P2 battery is 6.0 volts and the nominal capacity is ~1500 mAh.

Actual capacity depends on the drain current and the cutoff voltage of the device being used and can be as low as 4.0 - 4.4 volts.

Physically, the CR-P2 battery is very similar to the pair of non-rechargeable lithium 3V CR123A batteries placed side-by-side which feature physical dimensions of (H x D) 34.5 x 17 mm.

CR-P2 battery is manufactured by most popular battery brands and is almost always available, if not in local hardware and electronics shops, then at online shops and stores.

However, if one is unable to find a new CR-P2 battery and the use of a pair of CR123A batteries is supported by the device, feel free to replace one CR-P2 battery with a pair of CR123A batteries - just be sure about the orientation of the batteries.

Also, the rechargeable CR123A battery (also known as RCR123A battery) features a lower capacity (700-750 mAh vs ~1500 mAh), but it can be recharged hundreds of times, at least.

But, RCR123A battery features a nominal voltage of 3.6 volts (vs 3.0 volts of the non-rechargeable battery) and this voltage difference may cause functioning issues, even damage, to the devices intended to be powered by CR-P2 battery (6.0 volts) or a pair of CR123A batteries (2x 3.0 volts).

Long Story Short: CR-P2, BR-P2, 5024LC, 223A, or CR17-33 battery is a non-rechargeable lithium battery used for powering photo cameras and other similar devices that require bursts of energy, but also may be turned off for long periods of time.

Thanks to the low self-discharge rate of just 2-5% annually, the best CR-P2 models can be stored for years to come and still have at least 80-90% of their nominal capacity.

If the CR-P2 battery is being replaced by a pair CR123A batteries (if supported by the device!), be very careful about CR123A battery orientation and the battery type (rechargeable or non-rechargeable).
