Coin Batteries

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.

The Duracell 2025 Lithium Battery 4-Pack: Not everyone has a go-to brand of batteries, but I do, and it's Duracell. Maybe I'm a victim of their advertising campaigns but the other big brands advertise about as much. I buy Duracell brand because I think they make the highest quality, longest lasting batteries. Lithium batteries are known for their capacity vs alkaline-type, and coin cells being relatively small need high capacity for long life. I have enough devices that take the "2025" coin cell that I like to keep a few on hand at all times. A very tiny percentage of reviewers have mentioned that one battery of the multi-pack of coin cells they bought didn't work. If true, that's an extremely low failure rate and great quality control. I've never had that problem myself. Of course they're compatible with any device that takes a 2025, and you can't beat their value when it comes to price vs performance.

Very good, work well for my Key Fab.

These are great batteries. Some are made in USA! Rats, not button cells! Had a difficult time opening them.

These CR2025 batteries from Duracell are dependable and long-lasting. I used them in a car key fob and a small scale, and both devices powered up immediately. I also appreciate the added safety feature—the bitter coating and child-secure packaging give peace of mind if you have kids around. My only gripe is the packaging. It’s extremely tough to open without scissors, which is a bit frustrating when you're trying to quickly swap out a battery. Also, while the price is reasonable, I wouldn’t call it a deal just a fair cost for a trustworthy brand. Still, for performance and peace of mind, I’d buy them again.

These are the standard batteries we use for small electronics and they’ve been very reliable. They last a long time and work exactly as expected. Duracell is one of those brands I tend to trust for batteries, especially when it’s something you don’t want to replace constantly.

All’s well with this purchase! Recommended!

after not getting this item in my original order, 'zon refunded me. Placed order again and now installed on automobile key fobs. Works like they should! I didn't lick the battery so I don't know if it tastes as bad as advertised. Package secured.

Perfect for my VW car key , arrived on time , easy to fit , no more warning light on the dash , very happy with the purchase
