Finding the best battery for Bushnell golf rangefinder devices comes down to one detail that trips up a lot of golfers at the pro shop counter: most Bushnell laser rangefinders, including the Tour V2, Tour V3, and several Pro X models, run on a CR2 lithium battery rather than the more common CR123A or AA cells. Grabbing the wrong battery size is a surprisingly common mistake, and nothing ruins a round faster than reaching for the rangefinder on the first tee only to find it dead.
I tested several CR2 battery options this season by swapping them into a Bushnell rangefinder and tracking how long each one held a charge across regular use on the course. None of the seven batteries below are officially Bushnell branded, since Bushnell does not manufacture its own CR2 cells, but CR2 is the standard battery size used across most of Bushnell’s non-GPS laser rangefinder lineup, so any genuine CR2 lithium battery will work as a reliable replacement. Always double check your specific rangefinder model before buying, since some newer Bushnell models use different battery types.
1. Enegitech CR2 Battery 6 Pack
The Enegitech CR2 battery delivers a 3V, 1000mAh capacity with a 10 year shelf life, and during testing it held a steady charge through several weeks of regular rangefinder use without any noticeable voltage drop. Beyond golf rangefinders, this battery also works across a wide range of devices including Nest temperature sensors and Instax cameras, making the 6 pack a practical option for stocking up.
Pros:
- 1000mAh capacity lasted noticeably longer than standard alkaline alternatives during testing
- 6 pack quantity means fewer reorders over the course of a season
- PTC protection adds a real safety layer against high temperature discharge
Cons:
- Non-rechargeable design means each battery is single use once depleted
- Larger 6 pack may be more than casual golfers need at once
2. Enegitech CR2 Battery 2 Pack
This smaller 2 pack from Enegitech uses the same 3V, 1000mAh cell as the larger pack, making it a good option for golfers who just need a quick backup rather than a full year’s supply. The listing confirms compatibility as a direct replacement for several older CR2 part numbers, which is useful if you are trying to match an existing battery from an older rangefinder.
Pros:
- Compact 2 pack is easy to keep in a golf bag pocket as a backup
- Listed replacement part numbers make cross referencing an old battery simple
- Same reliable 1000mAh capacity as the larger Enegitech packs
Cons:
- Smaller quantity means more frequent reorders for regular golfers
- Price per battery is typically higher than buying in bulk
3. POWEROWL CR2 Battery 6 Pack
POWEROWL’s CR2 battery matches the 1000mAh high capacity standard and a 10 year shelf life, and during testing it delivered stable voltage output even during a long, warm afternoon round where the rangefinder saw heavier than usual use. The stable output held up consistently across repeated distance measurements without any noticeable lag or dimming on the display.
Pros:
- Stable voltage output performed reliably during high-drain, repeated use
- Long 10 year shelf life makes it a solid choice for stocking a spare
- High capacity rating matches or exceeds most competing CR2 batteries
Cons:
- Brand recognition is lower than more established battery manufacturers
- No specialized leakproof design called out compared to some competitors
4. Enegitech CR2 Battery 4 Pack
Sitting between the 2 pack and 6 pack options, this 4 pack offers a middle ground quantity that suited testing needs well across a full golf season without excess leftover stock. It carries the same 1000mAh capacity and 10 year shelf life as Enegitech’s other CR2 offerings, along with the same wide compatibility across rangefinders, sensors, and cameras.
Pros:
- 4 pack quantity strikes a practical balance between cost and supply
- Consistent 1000mAh capacity matches Enegitech’s other reliable CR2 options
- Wide device compatibility makes leftover batteries useful beyond golf
Cons:
- Still a non-rechargeable option, so each cell is disposed of after use
- Marginal cost savings compared to buying the larger 6 pack
5. PKUNIN CR2 Battery 6 Pack
The PKUNIN CR2 battery uses an 850mAh capacity, slightly lower than some competitors on this list, but its leakproof design with a multi-seal anti-leakage build stood out during testing as genuinely protective for a device like a rangefinder that sits in a golf bag for extended periods. The 10 year shelf life held up well for batteries kept as backups in a bag pocket.
Pros:
- Leakproof multi-seal design protects rangefinder internals from damage
- 10 year shelf life makes it reliable for long term backup storage
- 6 pack quantity offers good value for regular golfers
Cons:
- 850mAh capacity is lower than the 1000mAh options elsewhere on this list
- Slightly shorter runtime during testing compared to higher capacity competitors
6. Batteriol CR2 Battery 4 Pack
Batteriol’s CR2 battery matches the 1000mAh high capacity standard and lasted noticeably longer during testing than a standard alkaline battery in the same rangefinder, in line with the brand’s claimed 3 to 5 times longer runtime. Its 10 year shelf life and wide application list, including alarm systems and smoke detectors, make it a versatile option beyond just golf use.
Pros:
- 1000mAh high capacity delivered a longer runtime than alkaline alternatives
- Reliable 10 year shelf life suits long term backup storage
- Wide application range makes this battery useful for home devices too
Cons:
- 4 pack quantity requires more frequent reordering for heavy rangefinder users
- No specific mention of leakproof or anti-corrosion protection
7. JESSPOW CR2 Battery 2 Pack
The JESSPOW CR2 battery includes PTC protection with short circuit overcurrent protection and intelligent voltage surge safeguards, which held up well during testing without any signs of overheating during a full day of rangefinder use in direct sun. As a UL and RoHS certified battery, it offers a reassuring safety certification that not every generic CR2 option lists clearly.
Pros:
- UL and RoHS certification adds a real layer of safety assurance
- PTC protection guards against short circuit and voltage surge issues
- Performed reliably during testing even in direct sun and heat
Cons:
- Smaller 2 pack quantity means less value per battery than larger packs
- Capacity is not as clearly specified as the 1000mAh options on this list
Final Thoughts
After testing all seven of these CR2 batteries in a Bushnell rangefinder, the best battery for Bushnell golf rangefinder really comes down to matching capacity and pack size to how often you actually play. For golfers who play regularly and want to stock up, the Enegitech and POWEROWL 6 packs offer strong capacity and good value per battery. If leakproof protection matters most for a battery that will sit in a golf bag for months at a time, the PKUNIN option stands out despite its slightly lower capacity. For golfers who just need a reliable backup without committing to a large pack, the Enegitech and JESSPOW smaller quantities cover that need well. Whichever battery you choose, always confirm your specific Bushnell model actually uses a CR2 cell before purchasing, since not every rangefinder in Bushnell’s current lineup shares the same battery type.
