Storage life is one of the clearest advantages. Energizer states that its CR2 batteries can hold power for up to ten years when stored properly, making them practical for emergency kits, occasional-use rangefinders, camera bags, and equipment that may sit unused for long stretches. The listed replacement codes—DLCR2, CR15H270, and KCR2—also help buyers confirm that the cell matches equipment documentation before ordering.
The tradeoff is that the product information does not provide a specific milliamp-hour capacity or a numeric operating-temperature range. That means it is less useful for comparing fine-grained technical specifications against batteries such as the EBL, Tenergy, or POWEROWL. Nevertheless, the stated focus on modern, high-powered devices makes it a sensible general-purpose choice, especially for people who recognize the Energizer brand or already use its photo batteries in cameras.
Our recommendation goes to golfers and photographers seeking a simple, reputable two-pack with strong customer feedback and long-term storage capability. It is less appropriate for someone who wants the largest possible reserve of spare batteries or prioritizes a published capacity figure. Confirm your rangefinder requires CR2 rather than CR123A or another cylindrical format, then verify compatibility and current availability through the product listing.
Long-Term Storage Convenience
The stated ten-year storage life makes these cells useful in equipment that is used seasonally or kept as an emergency backup. Store them cool and dry, away from direct sunlight and extreme heat, to preserve their useful condition.
Reliable Familiar Brand

Buying Guide – How to Choose the Best CR2 Battery for Rangefinder
The right CR2 cell depends on your device requirements, how often you use it, where you store it, and how many spares you want to carry. The following factors help narrow the field without overlooking essential compatibility and safety details.
Confirm CR2 Compatibility
Begin with the rangefinder manufacturer's battery guide and the markings inside the battery compartment. CR2 cells are commonly associated with 3-volt lithium chemistry and a cylindrical format, but similar-looking names such as CR123A do not always represent the same physical size, voltage, or intended device use. Some listings explicitly warn against confusing CR2 with CR123A, and Tenergy additionally states that its cells are not compatible with Arlo cameras. These differences make the equipment manual more authoritative than appearance alone.
Compare Published Capacity
Capacity is one of the most useful numerical comparisons when it is published clearly. The Enegitech, POWEROWL, and EBL batteries state 1000mAh; PKCELL and DURNERGY state 850mAh; PHILIPS and Tenergy state 800mAh. The Energizer, Duracell, and Panasonic listings do not provide a capacity figure in the supplied information. A higher rated capacity can be attractive for frequent rangefinder use, but it is not the sole determinant of runtime because device demand, temperature, and usage patterns also matter.
Assess High-Drain Performance
Laser rangefinders are treated as high-drain specialty devices in this category because they repeatedly power distance measurement, displays, and controls. Duracell specifically describes its chemistry as high-power lithium for specialty equipment, while Tenergy highlights high pulse current for rapid readings and flash recycle times. DURNERGY similarly promotes short, consistent recycle time. These features can matter more than a large multipack when you want reliable operation in demanding equipment.
Choose the Right Pack Size
Pack size controls convenience, spare depth, and storage requirements. Two-cell packs from Energizer and Duracell cover one active set and a basic replacement, while the Panasonic single-cell format suits a one-battery replacement. Four- and five-packs provide more flexibility, and the six-, eight-, and ten-cell options from POWEROWL, EBL, and DURNERGY are better for people maintaining several devices. Larger packs are convenient for frequent play, photography assignments, sensor networks, or emergency supplies.
Consider Storage Life
A long shelf life matters when equipment is used seasonally or spare cells sit for extended periods. Energizer, Duracell, Enegitech, PHILIPS, POWEROWL, PKCELL, Tenergy, Panasonic, and EBL state shelf lives ranging from up to five or ten years depending on the listing. DURNERGY's supplied information contains a five-year shelf-life statement even though the title refers to long-lasting performance. Proper storage remains essential: keep cells cool, dry, and away from direct sunlight, fire, liquids, and intense heat.
Review Temperature Performance
Outdoor golfers and field users should pay attention to temperature specifications because low temperatures can affect device and battery performance. Tenergy states an operating range of -40 to 140 degrees Fahrenheit, while EBL lists -40 to 158 degrees. PHILIPS describes performance from -20 to +30 degrees Celsius, and PKCELL lists -22 to 140 degrees Fahrenheit. Duracell gives a wide-temperature claim without publishing exact endpoints in the supplied information. A broader range can offer more confidence for year-round use.
Check Device Compatibility Codes
Replacement codes can help distinguish a genuine match from a look-alike cell. Across the listings, common references include DLCR2, CR15H270, KCR2, ELCR2, EL1CR2, CR17355, 5046LC, 1CR2, and RLCR2-2. No listing should replace the manufacturer's instructions for your specific device. If multiple codes appear, use the exact model guide to confirm the requirement, especially when a rangefinder shares a compartment design with cameras, sensors, or other equipment.
Evaluate Safety and Storage
All of the products listed here are non-rechargeable or presented as disposable lithium cells, so they should not be put in a charger. Enegitech highlights PTC high-current discharge protection, while PHILIPS and EBL describe leakproof designs. These features can add confidence but do not replace careful handling. Avoid shorting terminals, mixing cells from different brands, exposing the pack to heat, and keeping loose batteries where children or pets could reach them. The Enegitech listing specifically advises a cool, dry storage environment.
How to Use and Care for Your CR2 Battery for Rangefinder
Start by checking the rangefinder manual for the required cell type, quantity, and installation orientation. Turn the device off, remove the old batteries, and inspect the compartment for dust, corrosion, or residue before inserting a fresh CR2 set. Match the positive and negative terminals with the molded indicators in the battery compartment, and avoid mixing old and new cells or cells from different brands.
For storage, place unused CR2 batteries in their original packaging and keep them in a cool, dry location away from direct sunlight, fire, liquids, and intense heat. Do not place loose cells in the same pocket as keys, coins, or other metal objects. Because these are non-rechargeable batteries, never attempt to recharge them, and dispose of used cells through an appropriate household battery-recycling program where one is available.
If a rangefinder begins showing a low-battery warning, power it down and replace the entire set as directed by the manufacturer. Clean the contacts gently if they appear dirty, taking care not to push debris deeper into the compartment. Before a round, trip, or photo session, check that spare cells match the device and remain within their useful storage condition. Temperature and usage patterns affect runtime, so carrying a spare set remains sensible even with a long-storage-life battery.
Frequently Asked Questions
Are CR2 batteries rechargeable?
No. The CR2 lithium batteries in this guide are non-rechargeable and are intended for one-time use. Do not place them in a battery charger or attempt to restore them. Even products with a long shelf life are designed to retain their charge while stored, not to be recharged after use.
Can a CR2 battery work in a laser rangefinder?
Many laser rangefinders use CR2 lithium cells, but the device manual should confirm the exact requirement. Several products in this guide explicitly list rangefinder compatibility, including Duracell, Enegitech, PHILIPS, POWEROWL, PKCELL, DURNERGY, Tenergy, Panasonic, and EBL. Check the required quantity as well, since some rangefinders take more than one cell.
Is CR2 the same as CR123A?
No. CR2 and CR123A batteries may look similar, but they are not always interchangeable in dimensions, intended applications, or device compatibility. Tenergy specifically warns that its CR2 cells are not interchangeable with larger CR123A cells. Use the size and replacement code printed in the rangefinder's manual rather than relying on appearance.
Does a higher mAh rating guarantee longer rangefinder runtime?
Not by itself. A higher capacity can provide a useful comparison when the ratings are measured consistently, but actual runtime also depends on the rangefinder's electronics, laser and display use, operating temperature, and battery condition. Several leading brands do not publish an mAh figure, so runtime claims and intended device support are also worth considering.
How should CR2 batteries be stored?
Keep unused cells in their original packaging, in a cool and dry place away from direct sunlight, intense heat, fire, and liquids. Terminals should not contact coins, keys, or other conductive objects. Following these practices helps protect the cells and the equipment in which they will eventually be used.
Should I mix battery brands in a rangefinder?
It is best not to mix brands or combine old and new batteries when the device expects a matched set. Consistent cells can provide more predictable power delivery and make troubleshooting easier. POWEROWL specifically advises against mixing brands, and using a complete set from one pack is a sensible general practice.
Which pack size is best for regular golf?
A four- or six-cell pack offers a useful balance for many golfers because it can provide an active set plus several spares. A two-cell pack is sufficient when replacement timing is predictable, while ten-cell packs suit frequent players or users who also maintain cameras and sensors. Choose the quantity that fits your device count and storage space.
Do temperature ratings determine cold-weather performance?
They are an important guide but not a guarantee of runtime. The listed products make varying temperature claims, ranging from broad numerical ranges to general descriptions of wide-range performance. Cold can reduce battery output and affect the rangefinder itself, so allow the device to acclimate as directed by its manufacturer and keep spare cells protected from extreme heat.
Final Thoughts on Choosing the Best CR2 Battery for Rangefinder
The Energizer CR2 pair is a balanced budget-oriented choice for buyers who want a recognized photo-battery brand, long storage life, and a simple replacement set. Duracell stands out as the editor's choice because its listing directly addresses laser rangefinders, high-drain specialty equipment, wide temperature performance, and a ten-year storage guarantee. For buyers seeking a premium four-cell package, the PHILIPS option combines the highest customer rating listed with extensive compatibility codes and long shelf life.
Prioritize verified CR2 compatibility before comparing any other feature. Once the size, voltage, and quantity are confirmed, choose according to usage pattern: a two-pack for occasional use, four to six cells for regular play and multiple devices, or a ten-cell inventory for heavy users. Published capacity, high-drain claims, temperature range, storage life, and safety features can then help distinguish the remaining options.
Product listings, ratings, package configurations, and prices can change over time, so review the current detail page before making a final purchase. Check the live specification panel and recent customer feedback, and follow the rangefinder manufacturer's guidance on battery type, replacement intervals, and safe handling. That final verification ensures that the selected CR2 battery is not only well suited to the device but also appropriate for where and how it will be stored.
