The Duracell CR2 Lithium Battery Made a Bold First Impression
The Duracell CR2 Lithium Battery, a seemingly small power source, plays a crucial role in many of our essential devices. Duracell, a name synonymous with long-lasting power, promises reliability and longevity with this battery. I was intrigued by the claims of its wide application, from digital cameras to critical medical devices, and wanted to see if it lived up to the hype.
What led me to this product was a recurring issue with my high-powered flashlight, vital for nighttime security patrols on my property. The standard alkaline batteries drained far too quickly, leaving me in the dark at critical moments. I needed a more reliable power solution, and the Duracell CR2 Lithium Battery seemed like a promising upgrade.
Unboxing the 2-pack was unremarkable, as expected with batteries. However, the packaging clearly stated the Duracell promise: Duralock technology preserves battery power for up to 10 years in storage. This was a significant selling point, as I often buy batteries in bulk and store them for later use. The build quality felt solid; each battery had a reassuring weight and a clean, professional finish.
Compared to generic lithium CR2 batteries I’ve used in the past, the Duracell stood out with its established brand reputation and the promise of Duralock technology. I’d previously used Energizer CR2 batteries, which performed adequately, but I was willing to pay a premium for the potentially longer lifespan and superior reliability of Duracell. I also considered Panasonic CR2 batteries but decided Duracell had a slightly better track record.
My first impression was one of cautious optimism. I was eager to test the battery’s performance in my flashlight and other devices to see if it justified the higher price point. The claim of a 10-year shelf life was particularly appealing, and I looked forward to evaluating its long-term performance.
Real-World Testing: Putting Duracell CR2 Lithium Battery to the Test
First Use Experience
The primary use case for the Duracell CR2 Lithium Battery was in my Streamlight ProTac HL USB flashlight, which I use nightly for security patrols on my rural property. I immediately noticed a difference in the flashlight’s brightness compared to the alkaline batteries I had been using. The light was noticeably more intense and consistent.
I also tested the battery in my wife’s digital camera. Her initial thoughts were, “Wow, it’s faster and the flash is brighter!”
The first test was in relatively mild conditions, with temperatures around 60°F and low humidity. However, I later subjected the flashlight to wet conditions during a heavy rainstorm, and the battery continued to perform flawlessly. There was no dimming or flickering, and the light remained consistently bright.
Installation was straightforward, just like any standard CR2 battery. I didn’t need any special tools or instructions. After about a week of daily use, the flashlight was still performing as brightly as the first day, and my wife continued to use her camera with excitement. There were no unexpected issues or surprises.
Extended Use & Reliability
After several months of consistent use, the Duracell CR2 Lithium Battery continues to impress. In my flashlight, it has lasted significantly longer than any alkaline battery I’ve used previously. I’ve only had to swap it out once for the second in the 2-pack.
There are no visible signs of wear and tear on the battery itself. The flashlight and camera both continue to function without any reduction in performance. The battery compartment is clean and dry, indicating no leakage or corrosion.
Maintenance is virtually non-existent; there’s nothing to clean or maintain. Just install and forget. Compared to my previous experience with alkaline batteries, the Duracell CR2 Lithium Battery is a clear winner. It provides longer-lasting power, greater reliability, and requires no maintenance.
