Reliable coin batteries — great for car key fobs and small devices
Usage context: I bought these specifically to replace the battery in my car key fob. The old one was still working, but I didn’t know how long it had been in there, so I wanted a fresh pair. I also use CR2025s in digital calipers and food scales. Expectations vs. reality: These Duracells worked exactly as expected — reliable, steady power with no issues. They last noticeably longer than the cheap generic batteries I’ve tried before. Compared to Energizer, I don’t see much difference in longevity; both are dependable. Details: Devices tested: car key fob, digital calipers, and food scales. Longevity: much better than generics. Reliability: consistent performance, no unexpected failures. Packaging: child-resistant, which is a plus. Price: higher than off-brand, but worth it for peace of mind. What I liked: Works perfectly in a car key fob Longer life than generics Reliable in precision devices (calipers, scales) Child-safe packaging What I didn’t: No real difference compared to Energizer Pricier than off-brands Who it’s for / not for: For: Anyone needing dependable CR2025s for car remotes, scales, calipers, or other small electronics. Not for: Buyers hoping these will outlast other premium brands. Bottom line: Duracell CR2025s are dependable, long-lasting coin batteries that work perfectly in car key fobs and other small electronics. They easily outperform generics, and while they don’t outlast Energizer in my experience, they’re a reliable, trusted choice worth the price. Read more
