🔋 Pack of 10 Tianqiu AG3 / LR41 / 192 Button Cell Batteries - Long Shelf Life, 1.5V, 0% Mercury, Expiry Date Included Review

They were dispatched quickly and arrived in perfect condition. I already installed all ten batteries and had to order a pack of 20 right away (my stupid bad one). All devices work great. I can't comment on the battery life yet and will update this if there are any issues. I am 100% satisfied and can recommend both the product and the seller. I would like to buy again.

Works well, good output judging by the brightness of my laser pointer. Good expiration date of 2023. These little button batteries are just what I need for the only laser pointer my cats love. I don't like using multiple disposable batteries of this type (the pointer takes 3 at a time). But since I have to use them, at least they are MUCH cheaper than the bigger brands and seem to be just as good.

They weren't the size I needed. I only had one number on paper. I should have taken the watch to the store instead of buying it live. They won't go away. I took them to my pharmacy and asked them to give them to someone who needs batteries for hearing aids that size. I didn't want to go through a return and they were so cheap I wouldn't worry. I hope they help someone who needs them.
