Description
The Panasonic CR2 is a compact high-performance 3V primary lithium battery designed for applications requiring high-rate discharge from a relatively small cylindrical cell.
Panasonic specifies the CR2 at 3V nominal voltage and 850mAh nominal capacity, with a standard continuous drain of 20mA. It measures approximately 15.6mm in diameter × 27.0mm in height and weighs approximately 11g.
Panasonic’s CR-series standard lithium batteries use manganese dioxide chemistry and are engineered for high-rate discharge performance. Panasonic specifically highlights cameras and lights among suitable applications.
The product supplied by ArcEin is the Panasonic CR2 Industrial Lithium battery shown in the actual product photograph.

CR2 vs CR123A — Important
Customers frequently confuse these two batteries.
CR2: 3V, 850mAh, approximately 15.6 × 27.0mm
CR123A: 3V, 1550mAh, approximately 17.0 × 34.5mm
They have different physical dimensions and capacities and should not be treated as interchangeable unless the device manufacturer specifically permits it.
Safety Information
This Panasonic CR2 is a primary/non-rechargeable lithium battery. Do not recharge it.
Do not short-circuit, dismantle, crush, puncture, incinerate or expose the battery to excessive heat. Observe correct polarity when installing it.
Keep batteries away from children and store unused batteries safely.
