CR2 battery type: Compatible cameras

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

CR2 batteries power almost exclusively cameras from the late 1990s and 2000s, usually two cells in parallel inside the body, and often just one in compact cameras. Typical models:

• Premium compacts: Contax T3, Ricoh GR1 / GR1s / GR1v / GR21, Fujifilm Klasse / Klasse S / Klasse W, Fujifilm Natura, Minox CD series.
• Rangefinders and panoramic: 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 counterpart in the standardized 15270 format (15 mm in diameter, 27 mm long). Pay attention to 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): is significantly above the CR2's rated voltage of 3 V. Some modern cameras can tolerate this, but older electronics from the 1990s may be damaged by it. Suitable, for example, for the Lomo MC-A; we offer the CR2 USB-C battery (3.7 V High Voltage) for this purpose.
• LiFePO4 (3.2 V nominal, often sold as 3.0 V): is very close to the CR2's original voltage and is the technically sound option for most film cameras.

If you are unsure whether your camera can tolerate 3.7 V, it is best to stick with a disposable CR2 or a LiFePO4-RCR2. Voltage damage to old electronics cannot be repaired.

Because it does not fit—and must not fit. CR2 (15.6 × 27 mm) and CR123A (17 × 34.5 mm) are chemically similar (both are 3 V lithium manganese dioxide), but they differ in mechanical and electrical dimensions. The CR123A is both wider and significantly longer, so it does not fit in a CR2 battery compartment. Conversely, the CR2 sits loosely in a CR123A compartment and does not make secure contact. The two are frequently confused in online retail, so always check the designation on the old battery cover or in the camera manual before buying.
