Battery type CR2 — Compatible Cameras

The CR2 is a 3-volt lithium manganese dioxide round cell (Li-MnO2) in photo format measuring 15.6 × 27 mm with a capacity of around 800 to 850 mAh. It was developed in the mid-1990s for the then new generation of highly compact premium point-and-shoots and APS cameras — smaller than the CR123A (17 × 34.5 mm), but powerful enough for motor-driven film transport and flash. Synonyms from industry and brand contexts: CR15H270 (IEC standard), CR-2W (Panasonic), KCR2 (Kodak), DLCR2 (Duracell), EL1CR2 (Energizer).

CR2 powers almost exclusively cameras from the late 1990s and 2000s — usually two cells in parallel inside the body, often only one in compacts. Typical models:

• Premium Compacts: Contax T3, Ricoh GR1 / GR1s / GR1v / GR21, Fujifilm Klasse / Klasse S / Klasse W, Fujifilm Natura, Minox CD series.
• Rangefinder and Panorama: Contax G1 / G2, Konica Hexar RF, Hasselblad XPan / XPan II, Fujifilm TX-1 / TX-2, Bronica RF645.
• SLR: Leica R8 / R9, Canon EOS 300 / 3000 / 300V / 300X (Rebel 2000 / K2 / Ti / T2), Nikon F55 / F65 / F75, Pentax MZ-5 to MZ-S, Minolta Dynax 3 to 60 (Maxxum 3 to 70).
• APS cameras: Canon ELPH 370Z, Leica C11, Nikon Pronea S, Minolta Vectis series, Kodak Advantix series.

Yes — the RCR2 is the rechargeable sister cell in the standardized 15270 format (15 mm diameter, 27 mm length). Be careful with the voltage: there are two chemical variants with significantly different behavior:

• Li-Ion (3.6–3.7 V nominal, freshly charged up to 4.2 V): significantly above the CR2 nominal voltage of 3 V. Some modern cameras can handle this, but older electronics from the 90s can be damaged. Suitable, for example, for the Lomo MC-A — for this we offer the CR2 USB-C Battery (3.7 V High Voltage).
• LiFePO4 (3.2 V nominal, often sold as 3.0 V): very close to the original CR2 voltage and the technically clean option for most photo cameras.

If you're unsure whether your camera can handle 3.7 V, you should stick with the disposable CR2 or a LiFePO4 RCR2 — voltage damage to old electronics is not repairable.

Because it doesn't fit — and it must not fit. CR2 (15.6 × 27 mm) and CR123A (17 × 34.5 mm) are chemically similar (both 3 V lithium manganese dioxide), but mechanically and electrically different in size. The CR123A is both wider and significantly longer and does not fit in a CR2 battery compartment. Conversely, the CR2 sits loosely in a CR123A compartment and does not make a secure contact. These two are often confused in online retail — always check the label on the old battery cover or in the camera manual before buying.
