The shelf life of CR2 batteries depends on the model and the brand, but it is typically 3+ years, with some brands having 10+ years shelf life batteries (for example, Duracell DLCR2 battery features an annual self-discharge rate of ≤1%), which are highly recommended for standby devices or emergency devices (panic lights, EDC flashlights, medical equipment, smoke detectors, security devices, etc.).ĬR2 batteries are fairly common and are offered by most reputable brands, and getting good ones from online shops and local stores shouldn't be a problem. When labeling their batteries, many manufacturers use the 'standard' label of CR2 but also add a letter or two to emphasize the brand, for example.ĬR2 battery equivalents are commonly labeled as 1CR2, DL-CR2, DLCR2, 5046LC, CR15H270, EL1CR2, KCR2, etc.ĬR2 batteries are typically manganese-dioxide lithium 15.6 x 27 mm non-rechargeable cylindrical batteries, with carbon-monofluoride lithium 15.6 x 27 mm non-rechargeable cylindrical batteries ('BR2 battery') being very rare. The typical capacity of the CR2 battery is in the 800 and 850 mAh range, although the actual capacity depends on the cutoff voltage of a particular device and drain conditions (discharge current, temperature, battery age, and similar). The physical dimensions of the CR2 battery are 27 mm (~1.063 inches) in height and a diameter of 15.6 mm (~0.59 inches). Since they are very similar in dimensions to CR2 batteries, they are often labeled 'rechargeable CR2' batteries.ĬR2 battery is a non-rechargeable lithium battery with a nominal voltage of 3.0 volts and the cutoff voltage of 2.0 volts.

If you have any questions contact us directly. This may mean additional shipping charges in which case you will be contacted within 48 hours. Note: We ship lithium batteries in accordance with U.S. High discharge characteristics for applications such as digital cameras, flash units, etc.Panasonic CR-2 3V Photo Lithium Battery Specifications: By enlarging the surface areas of the positive and negative electrodes, they allow a current as high as several amperes to be drawn. All cylindrical type manganese dioxide (CR series) Lithium batteries feature a spiral structure. These batteries offer stable voltage during discharge and only have a 1.0% self-discharge rate per year allowing you to store these batteries with out worry of them being completely drained. ![]() ![]() But best of all, they deliver a quicker recovery time between flashes, letting you snap more photos in a shorter span of time. They deliver superior performance and long shelf life, so your camera will always be at full power. Panasonic CR-2 3V Photo Lithium Battery are a high-voltage battery specifically designed for today's 35mm, APS and digital cameras.
