If you are serious about your golf game, choosing the best CR2 batteries for rangefinder use is just as important as the device itself. A dead battery mid-round can cost you critical yardage reads. This guide covers the top CR2 lithium batteries available in 2026, evaluated for capacity, shelf life, reliability, and value.
What to Look for in a CR2 Rangefinder Battery
CR2 batteries are compact 3V lithium cells that power most modern golf rangefinders, laser devices, and photo cameras. When buying, focus on capacity (measured in mAh), shelf life, operating temperature range, and leak-proof construction. A high-quality CR2 battery should deliver 2,000 to 3,000 measurements per charge, which translates to roughly 6 to 12 months of regular play.

Final Thoughts
Picking the best CR2 batteries for rangefinder use comes down to a few practical considerations. Here are the key factors to guide your decision:
- Capacity: Aim for 1000mAh if you play multiple rounds per week for the longest runtime
- Shelf life: A 10-year storage rating means you can buy in bulk without waste
- Pack size: Single or 2-packs suit occasional players; 6-packs and 10-packs offer better cost-per-battery value for frequent golfers
- Temperature performance: If you play in cold climates, prioritize batteries rated for sub-zero temperatures
- Leak protection: Look for anti-leakage or PTC-protected designs to safeguard your rangefinder’s battery compartment
