The Panasonic CR2 3V Lithium Battery is the go-to power source for golfers who rely on laser rangefinders to gain the competitive edge on the course. Engineered by Panasonic — a global pioneer in lithium battery technology — this compact yet high-performance cell delivers consistent 3V output round after round. Whether you use a Bushnell, Leupold, Nikon, Callaway, or another leading rangefinder brand, the CR2 fits most laser-based models and keeps your device performing at its sharpest. A must-have spare for any serious golfer's bag.
Golf rangefinders demand a battery that can supply short, powerful bursts of energy to drive the laser emitter and instantly process return signals. The CR2's Lithium Manganese Dioxide chemistry excels at exactly this: it provides a stable, flat discharge curve so your yardage readings stay accurate right up until the battery is fully depleted — no gradual fade in performance.
Unlike standard alkaline batteries that lose capacity rapidly in cold conditions, the Panasonic CR2 lithium cell maintains its rated output from -40°C all the way up to +70°C. This makes it equally suitable for frosty winter links rounds or scorching summer days on the fairway, so you never have to worry about your rangefinder letting you down at a critical moment.
