# Which battery does a Bushnell rangefinder use? Source: https://pinandyard.co.uk/blog/bushnell-rangefinder-battery Published: 2026-10-12 Publisher: Pin and Yard **In short:** Most Bushnell Tour lasers, including the Tour V6 Shift and Tour V7 Shift, take a CR2 3 V lithium cell, and their listings state one is included. The compact A1-Slope uses a built-in rechargeable battery charged via USB-C. Check the battery section of your manual to confirm your exact model. A Bushnell rangefinder will not do much with a flat battery, and buying the wrong cell is an easy mistake. Bushnell uses two approaches across its golf lasers: replaceable CR2 lithium cells and built-in rechargeable batteries. This guide shows which current models use which, how to change a CR2 or charge a rechargeable model, how to spot a weak battery and how to store spares safely. ## Battery by model The A1-Slope listing states 3,000+ target acquisitions or about 40 rounds per charge; a second A1-Slope listing quotes 50+ rounds. The Phantom 3 Slope is a GPS unit rather than a laser and lists a battery life of 14 hours. For models not listed here, the manual or Bushnell's website gives the battery type. | Model | Battery | | --- | --- | | Tour V6 Shift | CR2, included in the box | | Tour V7 Shift | CR2, included in the box | | A1-Slope | Built-in rechargeable, USB-C | | Phantom 3 Slope (GPS) | Rechargeable, USB-C cable in the box | Bushnell golf devices and their power source (from listings) [Compare Bushnell models side by side](https://pinandyard.co.uk/best/bushnell-rangefinders-compared) ## CR2 or rechargeable: pros and cons A CR2 cell is a small 3 volt lithium battery sold in supermarkets, camera shops and online. Its advantage is that you can carry a spare and swap it in seconds on the course. The downside is the running cost of replacement cells and the need to remember a spare. A built-in rechargeable battery avoids buying cells and is topped up from any USB charger, but if you forget to charge it there is no quick fix on the course. - CR2: easy swap, long shelf life, carry a spare. - Rechargeable: no cells to buy, charge via USB-C, cannot be swapped mid-round. ## How to change a CR2 battery If the display is still blank, try a second new cell; cheap or old stock CR2 batteries can be weak. Our [Bushnell troubleshooting guide](https://pinandyard.co.uk/blog/bushnell-rangefinder-not-working) covers other causes. 1. Find the battery compartment, usually on the side or underneath the laser. 2. Open the cap or door, often with a coin or your thumbnail, depending on the model. 3. Remove the old cell and note which way round it was fitted. 4. Insert the new CR2 matching the plus and minus marks in the compartment. 5. Close the cap fully so the seal sits properly and keeps water out. 6. Press the power button to check the display. ## Charging a rechargeable model Use the supplied USB-C cable and a standard UK USB plug adaptor or a computer port. Charge fully before the first round and after every round or two, depending on how often you use it. Avoid leaving it in a hot car or charging it on a radiator. The manual will explain what the charge indicator shows on your model. ## Getting the most from each battery A few habits stretch battery life on either type. Turn the device off, or let it time out, between shots rather than holding the button for long scans. Keep it out of hard frost in the car boot overnight, since cold lithium cells deliver less power until they warm up. Remove a CR2 cell if the laser will sit unused over the winter, so a slowly discharging cell cannot leak or leave the device flat in spring. For rechargeable models, a full charge before the season and regular top-ups suit most lithium batteries better than running them completely flat every time. If the battery life drops noticeably after several seasons, contact Bushnell about service options rather than opening the housing. If you are weighing up a new laser and battery type is a deciding factor, our [rangefinder guide](https://pinandyard.co.uk/best/best-golf-rangefinders) notes the battery or charging method for each model where the listing states it. ## Signs your battery is running low Cold weather makes these signs appear sooner, so a cell that seemed fine in summer may struggle in winter. If you play a lot of winter golf, keep the laser in an inside pocket between shots and carry a spare CR2. - The display looks dim, faint or flickers. - A battery icon appears or flashes in the viewfinder. - Readings take longer or fail more often. - The device switches off on its own. Note: CR2 cells are lithium batteries. Store spares in their packaging away from keys and coins, keep them away from children, and recycle used cells at a battery collection point rather than in household waste. ## Frequently asked questions **Is a CR2 the same as a CR123A?** No. They are different sizes and are not interchangeable. Use the cell your manual specifies. **How long does a CR2 last in a Bushnell laser?** It depends on use, temperature and the model. Most golfers replace it once or twice a season; carry a spare to be safe. **Can I use a rechargeable CR2?** Check your manual. Rechargeable CR2 cells can have a different voltage, and the manual will say whether they are suitable. ## Buying guides on this topic - https://pinandyard.co.uk/best/bushnell-rangefinders-compared - https://pinandyard.co.uk/best/best-golf-rangefinders - https://pinandyard.co.uk/best/best-golf-rangefinders-under-250 ## Sources - [Bushnell Golf](https://www.bushnellgolf.com/)
