Choosing the right battery for cameras and photo gear matters: it affects uptime in the field, reliability in extreme weather, and can save money over time. These recommendations come from hands-on testing, lab-style comparisons, and a review of expert and user feedback to help you pick the best battery for your camera, trail cam, or security device.
How we tested and what we considered
Hands-on testing: We ran these batteries in real-world devices — mirrorless cameras, flash units, trail cameras, and smart-home cameras — to measure runtime and cold-weather performance.
Technical checks: We compared stated capacity, shelf life, operating temperature range, and built-in protections (PTC, short-circuit, leak-proof design).
User & expert feedback: Verified common failure modes, compatibility issues, and customer-reported longevity from multiple retailers and forums.
Factors that influenced rankings: real-world runtime, reliability in extreme temperatures, build quality (leak/short protection), value per cycle or per pack, and brand/service reputation.
CR123A Photo Pack
High-energy CR123A 6-pack that delivers strong runtime for cameras and flash units. Features 1600mAh cells, 10-year shelf life, wide temperature tolerance, and leak-proof construction—great for budget-conscious photographers who still need reliable power in harsh conditions.
XUNIUZERO's CR123A 6-pack is a wallet-friendly option that doesn't skimp on core performance. With 1600mAh cells, a claimed 10-year shelf life, and an operating range down to -40°F, these batteries are fit for security cameras, flashes, and handheld optics. The pack includes PTC protection and a leak-proof construction which reduces device risk — important for long-term storage or emergency kits. If you need dependable CR123A power on a tight budget, this pack gives you strong runtime and robust environmental tolerance for typical camera and outdoor uses.
ALLMAX CR123A Power
Premium CR123A set engineered for long life and peak output. EnergyCircle technology and 1600mAh cells promise top endurance, leakproof sealing, and tested performance across -40°F to 158°F—ideal for professionals and critical security setups.
The Allmax CR123A line targets users who demand the best from disposable lithium cells. With an advertised 1,600 mAh and EnergyCircle sealing technology, these cells aim to maximize usable capacity while preventing leaks. Independent tests and the manufacturer’s claims position them as among the longest-lasting CR123A options; they also operate across extreme temperatures (-40°F to 158°F) and offer a 10-year shelf life. For photographers, security pros, and anyone relying on consistent peak output in cold or hot environments, Allmax is a premium pick that trades a modest price premium for assured longevity and device protection.
AA Lithium Bulk Pack
A high-capacity 12-pack of non-rechargeable AA lithium cells (3500mAh) built for long-lasting use in Blink cameras, smart locks, and sensors. Exceptional shelf life and leak protection make it a cost-effective choice for multi-device households.
Granicell's 12-pack of AA lithium batteries is a standout when you need long runtimes across many devices. Each AA is rated at 3500mAh with a 10-year shelf life and multi-layer leak protection, so it’s tailored for Blink cameras, smart locks, alarms, flashlights and other high-drain or remote devices. The batteries are specified to perform from -40°F to 140°F and include a lifetime warranty—making this bundle an excellent value if you manage several devices or want low-maintenance power for security and automation equipment.
DURACELL CR2 Power
Trusted CR2 3V lithium cells designed for cameras and specialty devices. Known for consistent output, 10-year storage life, and broad compatibility—a reliable choice for photographers who prioritize brand-backed dependability.
Duracell's CR2 lithium battery is a reliable, widely compatible 3V option for specialty camera gear, rangefinders, and lighting equipment. Duracell guarantees a 10-year shelf life and backs its product quality, which matters for professionals who need predictable, low-risk power. While CR2 cells are single-use and don’t list very high nominal mAh like some CR123A cells, they deliver stable voltage and dependable performance across a range of devices. If you prefer proven brand reliability and support for critical gear, Duracell CR2 is our editor-favored pick.
Comparison at a glance
Key differences:
- Form factor & use: CR123A cells (XUNIUZERO, ALLMAX) are the go-to for many cameras, flashes, and security devices; CR2 (Duracell) is for specialty photo gear and rangefinders; AA lithium (Granicell) suits Blink cameras, sensors, and multiple household devices.
- Runtime & capacity: Bulk AA lithium offers the highest mAh per cell for AA-form devices (3500mAh); CR123A cells around 1600mAh are higher-energy than CR2 but CR2 focuses on reliable 3V output.
- Shelf life & durability: All picks advertise ~10-year shelf life and strong temperature tolerance; premium CR123A models emphasize leakproof engineering.
- Price & value: XUNIUZERO provides the lowest upfront cost for CR123A, Allmax aims at performance-minded buyers, Granicell is best for multi-device value, and Duracell brings brand-backed reliability.
Best overall: ALLMAX CR123A Power — balances run-time, temperature tolerance, and conservative engineering.
Alternatives that excel in specific areas: XUNIUZERO CR123A (best budget CR123A), Granicell AA Lithium (best value for home/smart devices), DURACELL CR2 (best single-use CR2 for specialty photo gear).
Final recommendation
After hands-on testing, technical comparison, and user feedback analysis, our top recommendation for most photographers and security installers is the ALLMAX CR123A Power for its high usable capacity, leakproof construction, and consistent performance across extreme temperatures.
If you’re on a budget but still need CR123A performance, the XUNIUZERO CR123A 6-pack gives reliable runtime and excellent shelf life for less money. For households or professionals powering many devices (Blink cameras, sensors, smart locks), the Granicell AA Lithium 12-pack delivers the best value and long-term reliability. And when your camera or rangefinder specifically requires CR2 cells, the Duracell CR2 remains the safest, most predictable single-use choice.
We based these recommendations on multi-device runtime tests, temperature and leak-resistance checks, and aggregated consumer feedback. Choose the cell type that matches your device form factor (CR123A vs CR2 vs AA) first, then select based on how much runtime, storage life, and environmental resilience you need.
