2025 Batteries (2 Pack), 3V Lithium Coin Batteries With 3-in-1 Child Shield

They work exactly as intended. Amazing piece of little technology.

Great price

No issues, have been using this for my car key and it's been working for years. Rarely need to replace it—a much better price here than going to an auto shop.

perfect

Pretty much what you would expect - it's a button battery. They work as described and the expiration date on my package shows it is good through 2032. The main problem with these is getting the batteries out of the package. You basically have to destroy the package to get to the battery, and even then they are encased inside another plastic shell. I realize they are trying to make these safe so kids don't swallow them, but the extremes they go to are ridiculous! If you have a multi pack, you end up with a bunch of loose batteries and no way to tell when they expire as the package is trashed just getting them out! If you're elderly, forget it - you'll end up with batteries you can't use because you can't get them out of the package! The batteries themselves are 5 star, but the packaging is more a 1 or 2 star rating for difficulty. IMO they should make packaging specific for who is buying them. Parents can choose the impossible to open packaging, and everyone else can choose packaging that is easier to open.

Do not remove child proof coating. I cannot believe children would get a hold of and swallow it. Measure battery voltage before installing it.

Good price

Replaced my buddies key fob with it and it works like it brand new 👍🏾👍🏾
