It’s a worse feeling—to get out onto the first tee only to discover that your rangefinder is dead. If you’ve invested in a good rangefinder, you will need a replacement battery, and there are different brands to opt for.

But the goal is to ensure the unit remains fully powered throughout your round of golf. Duracell and Panasonic are the top brands that come to mind. However, picking the right battery requires knowing the particular model that works for your device.

Here is the list of my top 4 recommended batteries for golf rangefinders and why I recommend them, in case you’re in a hurry:

• The best rangefinder battery of all time: Panasonic CR2 Rangefinder Replacement Batteries (2PK)
• Best value for money rangefinder batteries: Duracell CR2 High Power Lithium Batteries
• Best budget rangefinder battery: Shockli 3V CR2 Lithium Battery, 1000mAh
• The Best CR123A Rangefinder Battery: Surefire CR123A Lithium Battery

I have tested, reviewed, and ranked these batteries based on long-lasting power, stable voltage output, quick recharge time, and temperature resistance.

After using the Bushnell Tour V3 rangefinder for a while, I realized it sucks through batteries (a separate review is coming up soon). Unfortunately, the CR2 3V battery in this device is pretty expensive to buy in retail.

This prompted me to research where to buy rangefinder batteries, and I realized it’s a common problem among many rangefinder owners.

During my research and testing, I found the above four batteries best for golf rangefinders. However, they are all built with unique selling points. Before buying a particular battery brand, you must know what batteries work with your rangefinder model.

First, Know Your Rangefinder Battery Type

“What kind of battery is used in a golf rangefinder?” is a popular question when looking for the best replacement batteries to buy for their device. Both expensive and affordable rangefinders for golf (or even hunting) use rechargeable lithium-ion or non-rechargeable alkaline/lithium batteries.

Here are the popular batteries found in golf rangefinders, their unique purpose, and how to determine which one is used in your device:

For value for money, Shockli CR3 batteries are the clear winners. While they’re advertised as having a 1000 mAh capacity, most CR2 batteries only offer 800 mAh.

What sets Shockli CR3 batteries apart is their excellent performance at 800 mAh, combined with PTC protection. This feature proved invaluable during your rangefinder use in harsh weather conditions.

What truly makes these batteries a steal is the price point—four batteries for under $9! I used them extensively for golf and hunting in the early morning, and they performed admirably.

Golf rangefinders like the Bushnell Pro X7, Pro X7 Slope, Pro 1M, and 1M Slope use CR123A batteries. While I don’t have these models, I researched user reviews extensively and realized that the battery boasts a wide temperature tolerance.

I only bought it for a 5-month test. Remarkably, it showed no signs of leakage after a month of inactivity, maintaining its peak performance.

This battery’s ability to withstand extreme humidity sets it apart as the best rangefinder companion.

What I don’t like about this battery

• It’s still not rechargeable.

How Long Will A CR2 Battery Last In A Rangefinder?

CR2 batteries have a capacity of around 800-1000 mAh, which should last for several months to a year of average use in a rangefinder.

However, the battery life may be shorter if you frequently use features like image stabilization or shoot in cold conditions.

In other words, the lifespan of a CR2 battery in a rangefinder can vary depending on how often you use the device and the specific model of the rangefinder.

This is why carrying spare batteries for extended outings is ideal so you can be sure your rangefinder remains operational throughout your round of golf.

Wrapping Up

Whether you use a cheap or expensive rangefinder model, it is still possible to experience battery issues, requiring you to buy a replacement one.

While pursuing new batteries, I am happy I encountered a few options that performed excellently well. I am also glad that I can review and recommend them to you; suppose you’re also looking for a good rangefinder battery.

It is worth mentioning that the one I enjoyed so much is the Panasonic CR2 Rangefinder Replacement Batteries (2PK), which is why it ranks first in this review.

Whichever option you eventually settle for, ensure it has (or promises) a longer lifespan. Good luck!
