Only on Amazon!!!
I needed to replace the batteries in my Christmas Light Up Necklace. After searching all of my local stores without success, I finally found them on Amazon. They are as advertised, great quality, perfectly priced and arrived on time. I highly recommend this product.

Long-lasting and Secure Coin Batteries
Long-lasting and Secure Coin Batteries These Energizer 2032 lithium coin batteries impressed me with their dependability and thoughtful design. I originally bought them to replace the battery in a car key fob, and they worked right out of the package with strong, consistent power. Energizer claims up to 10 years of shelf life, which makes it easy to keep a pack on hand for future needs without worrying about them draining prematurely. The packaging includes a 3-in-1 child-resistant shield, which was a nice touch. The coin cell size makes these potentially dangerous for kids, so I appreciated the extra safety measure that requires some effort to open but is still manageable for adults. The batteries themselves are clearly marked and easy to install, and I noticed no drop in performance compared to the original factory-installed battery. While these are primarily marketed for key fobs, fitness trackers, and medical devices, they’re versatile enough to work in scales, thermometers, and other small electronics around the house. The only minor drawback is that the protective packaging can be a bit stubborn to open, but I’d rather have that than risk accidental access by children. Bottom line: A reliable, safe, and long-lasting coin battery choice from a trusted brand—well worth keeping stocked at home.

Good price.
Batteries work great. The small 6 pack was shipped in a box that could have held 50 of them. This item could have been shipped in a flat envelope. Why???

Reliable batteries - horrible packaging
Battery works fine, as expected. Totally a 5 Would give it a -5 for packaging. This is my first time dealing with the new packaging and it is HORRIBLE. I know this is not on Energizer, but it they don't hear from consumers, they'll think we're happy. We are not! I wonder if enough adults go to the ER with multiple cuts, it might be changed.

direct replacement
Direct fit for a dead CMOS battery. Last one lasted 12+ years this new one should last at least as long. Good price point, do recommend

With a freshness date of 2036, I knew these are new, and not old stock.
There is something about Energizer batteries that makes them better, and these coin batteries are no different.
