Panasonic CR-2PA/1B CR2 Lithium Battery 3V

The Panasonic CR-2PA/1B is a single CR2 lithium battery rated at 3.0 volts, engineered for devices that demand compact, high-energy power cells. Panasonic's proprietary sealing technology is the key differentiator here — it helps the battery maintain its discharge performance over time, which is particularly important for devices like golf rangefinders and security sensors that may sit idle between uses but need to perform reliably when called upon.

Lithium chemistry gives the CR2 a clear advantage over alkaline alternatives in both energy density and weight. It performs well across a range of temperatures and maintains a more stable voltage output throughout its discharge cycle, meaning devices like tactical flashlights and cameras get consistent performance rather than a gradual fade. The single-pack format keeps the upfront cost low, though frequent users of CR2-powered devices may find it more economical to purchase in bulk.
