Rangefinders for golf are now part and parcel of most golfers' equipment as they seek to improve on their accuracy. From measuring how close you are to the green to identifying where hazards are positioned, the devices provide you with up-to-date and precise information. But have you ever considered what batteries do golf rangefinders use? And how much impact a small battery can have on your rangefinder's performance?

Various rangefinders employ varying battery types, and selecting the appropriate one is not only likely to maximize the operating time of the device but also avoid failure during a critical situation.

This article will guide you through the most used battery types in golf rangefinders, their pros and cons, how to find the proper battery for your unit, and some helpful hints on replacing them.

Part 1. Why is the Rangefinder Battery Type So Important?

The rangefinder battery isn't just the power source of a golf rangefinder — it's the secret to how well and how regularly your device will perform. The choice of the proper type of battery affects several critical functions of the device.

1. Battery Life (Runtime)

A suitable battery enables your rangefinder to withstand a few rounds of golf without repeated replacement or recharging.

Different batteries contain different capacities and rates of discharge. For example, a lithium battery usually has longer running time than an alkaline battery, and therefore it is better for hard use.

2. Performance Stability and Responsiveness

Rangefinders employ speedy data processing and laser transmission to deliver instant readings. A constant voltage-supplying battery is required to ensure that the device remains responsive and precise.

Low-voltage or low-grade batteries may cause slow measurement rates, inaccurate distances, or even screen flickering.

3. User-Friendliness

The desire for ease of recharge or battery replacement also figures into overall user satisfaction. Some rangefinders use rechargeable lithium-ion batteries that can be charged using a USB connection, whereas others use disposable CR2 or AA batteries.

If you plan on traveling extensively or playing clubs that are far from your residence, an ergonomic battery to replace can be a huge advantage.

4. Long-Term Cost

Reusable batteries might be more expensive initially but ultimately earn their keep, especially if you go golfing regularly. Disposable batteries like CR2 or AA batteries, on the other hand, might seem cheap to purchase at first but become costly when purchased over and over.

Part 3. How to Identify What Kind of Battery Your Golf Rangefinder Takes?

If you don't know what battery your golf rangefinder requires, don't worry — it's just a few simple and easy steps. Having the proper type of battery will avoid destroying the unit or to get the unit running right on the course.

1. Read the User Manual or the Product Label

The easiest method is to take a look at the user manual that was included with your device. Most companies put the battery type down clearly in the "Specifications" or the "Power Supply" section.

Also, check the packaging box, device body, or the battery cover — most manufacturers stamp the model of the battery (e.g., "CR2 3V" or "Use only AAA batteries") on a prominent place.

Tip: If you lose your manual, you can often download a PDF version from the manufacturer's home website.

2. Visit the Manufacturer's Website or Help Page

If the manual or packaging is not available, visit your rangefinder maker's official website.Search for your model on the support or FAQ page. Most reputable brands provide clear specifications, replacement guides, and even battery safety tips online.

3. Inspect the Battery Compartment

Physically opening the battery compartment is another easy and accurate way to determine the required battery type. Inside the compartment, you’ll usually find:

A label or mark identifying the type of battery, i.e., "CR2 Only," "1.5V AA," or "Rechargeable Only."

In some cases, you can even observe the shape/size of the battery, which also gives a good indication (e.g., short fat cylinder most likely is CR2 and long thin one would be AAA).

Always power down the device before opening the battery compartment to prevent accidental damage or data loss.

Part 4. Battery Life and Replacement Tips

To ensure that your golf rangefinder continues to function smoothly round after round, discover the average battery life and follow best practices in replacement and maintenance. The following are type-specific guidelines for the different kinds of batteries used in golf rangefinders:

Typical Lifespan:

A high-quality CR2 battery can be expected to take 2,000–3,000 measurements, equivalent to about 6 to 12 months of usage, depending on the frequency of play and usage of the rangefinder during each round.

Replacement Tip:

If you play frequently (2–3 times per week), consider replacing the battery every 6 months proactively to avoid unexpected shutdowns. Occasional players may get up to a year of use.

2. Rechargeable Lithium-Ion Battery

Charging Routine:

Always keep the battery charged to capacity prior to a round, particularly if the device has GPS or Bluetooth capabilities, which require additional power.

Monitor the battery indicator, if present, periodically, and keep it away from deep discharge (letting it fully run down), as it will reduce its lifespan.

Lifespan:

Most rechargeable lithium batteries will last for hundreds of charge cycles (usually 2–3 years) before they begin to display a loss in capacity.

Pro Tip:

If you will not be using your rangefinder for an extended period (e.g., off-season), leave the battery charged at 50–70%, and charge it periodically to maintain its health.

3. Prevent Battery Leakage

Why It Matters:

Battery leakage — especially from alkaline AAA or AA batteries, can corrode the internal components of your rangefinder, causing permanent damage.

Prevention Tips:

If you won't be using your device for weeks or longer, remove the battery and store it separately in a cool, dry location.

Keep the rangefinder away from extreme heat or humidity, which will accelerate battery drain.

Carry a Spare Battery:

For non-rechargeable units, it's a good practice to carry a spare CR2 or AAA/AA battery in your golf bag, especially if:

• You're competing in a multi-day event.
• You're traveling abroad for golf and may not readily get replacement batteries.
• Your current battery is approaching the end of its approximate lifetime.

For rechargeable units, consider taking a portable power bank or USB charging cord, particularly if your device has fast charge functionality.
