Golf Range Finder Batteries

A golf range finder is a device used to measure the distance from the golfer to a specific target on the course, such as a flagstick, tree, or bunker. It helps golfers make more accurate decisions about which club to use and how to approach shots.

Most golf rangefinders use a CR2 lithium battery, though some models use a CR2032 coin cell or a AAA battery. Always check your rangefinder's manual — popular brands like Bushnell, Garmin, and Precision Pro typically use CR2.

A flat or failing battery is the most common reason a golf rangefinder stops working. If the display is dim, the laser is slow to respond, or the device won't turn on, replace the battery first before assuming a fault.

A CR2 battery is a lithium coin-style battery with a nominal voltage of 3 volts. It's commonly used in small electronic devices, such as digital cameras, laser pointers, key fobs, and some security systems.

A CR2 battery in a golf rangefinder typically lasts 6–12 months with regular use (approximately 2–3 rounds per week). Battery life varies by model, how often you use the laser, and whether you leave the device on between shots.

Most rangefinders have a screw-off or slide-off battery compartment on the side or bottom of the device. Use a coin to open it, remove the old battery, and insert a new CR2 with the positive (+) end facing the correct direction as marked inside the compartment.
