Good batteries; Don't like the packaging.
A. H. McCurdy—September 17, 2025
The batteries work just fine. I deducted a star because I really don't like the difficult to open retail packaging for products that are shipped directly to the customer instead to a retail store. I suggest a box like the boxes that Duracell uses for Procell packaging. Read more

Perfect, and much cheaper than buying at big box stores.
Kristoffer O.—December 6, 2024
Bought these, as they are kind of rare/hard to find. Not as easy as the 2016, or 2032s. Also, most small battery specialty shops are now going out of business around here so these are becoming even harder to find. The seller was very quick to get these out, and these work perfectly. Read more

Great Purchase
Steven Angello—December 22, 2024
Batteries are so expensive, and I like to purchase brand names when I need them. This was a great deal on a name brand battery. Read more
