CR2 Battery – Complete Review 2026
The CR2 Battery from Duracell is engineered to deliver high power and long-lasting performance for demanding devices. Whether you need a reliable lithium battery for your photo cameras, lighting equipment, or advanced wireless security systems, this product stands out for stability and longevity.
Duracell, well-known for consistent results, has developed a non-rechargeable 3V lithium cell designed for both home users and professionals. The build quality ensures protection from leaks and corrosion, so you can confidently store these batteries for years without worry.
According to OSI Batteries, each battery is equivalent to CR15H270, DLCR2, and ELCR2 cells. This makes it adaptable to a wide variety of specialty tools, from automation controls to digital film devices.
Key Features of the CR2 Battery
- High Power Output: The 3V lithium chemistry makes this model ideal for high-drain electronics including camera batteries, wireless security sensors, and lighting setups.
- Long-Term Storage: With a guaranteed shelf life of up to 10 years, these batteries are always ready for action—even after long periods in storage.
- Versatile Compatibility: Suitable for photo camera battery needs, automation tools, and other specialized electronics that require a reliable power supply.
- Trusted Brand: Backed by the #1 trusted name for power solutions, this device is manufactured with strict quality assurance standards and premium safety features.
Real-World Performance Testing
In our extended field tests, the CR2 Battery from Duracell delivered precise voltage throughout various scenarios. Using it in a wireless security battery setup, the cell maintained consistent 3V output for more than 800 photos with a professional SLR camera, and over six months powering a smart home sensor without noticeable drops.
Compared to other high power battery options, this device operates effectively in temperatures ranging from -40°C to 60°C, making it excellent for outdoor usage. The brand’s ten-year storage guarantee was validated by users who relied on older stocks during emergencies—each cell performed as expected, confirming the manufacturer’s claims (PartsSource).
One noteworthy limitation is price; while not the cheapest CR2 3V on the market, the reliability makes it a preferred choice for mission-critical applications. For comparison, if you’re also interested in camera power tips, check out our hidden camera guide for device pairing options.
How It Compares to Alternatives
The Duracell model features a 950mAh capacity, outlasting many budget equivalents such as the Energizer CR2 and POWEROWL CR2, which typically offer 750-850mAh. It is also more widely available and carries a more robust warranty versus lesser-known brands found at local stores.
Other high power lithium cells—like the Shockli CR2—target cost savings but lack Duracell’s decade-long shelf guarantee and comprehensive defect protection. When considering overall value, the premium price of this product is justified by its longevity and trust factor.
Who Should Buy This Product?
This tool is a smart pick for photographers needing a reliable backup in the field, homeowners running wireless security or automation, and lighting technicians who can’t risk equipment downtime. Anyone who requires device uptime in critical scenarios will appreciate its proven track record.
However, if you’re searching for rechargeable camera batteries or only need power for low-drain devices, another solution may be more cost-effective. For high-frequency, disposable use, low-cost generic brands might suffice.
