Eunicell20 AG1 / 164/364 / LR621 Button Cell Battery Long Shelf Life 0% Mercury (Expire Date Marked)

These small batteries are perfect for small items, like watches. They work well, and are a great value!

I needed some small cheap batteries for a transformer that I didn’t come with anything. These did the trick. I didn’t need something expense like energizer or durecell since I won’t keep the lights on for long periods. It was mostly to make sure the light function actually worked. As for the packaging, I like that each one is individually packed and you don’t have to open up the entire pack to get one or two out.

We have quit a few Christmas ornaments and do-dads that light up using these batteries. I purchased some of these a year ago, and the ones I remembered to remove from the ornaments last year, still worked fine when I put them back in this year. The price is great compared to purchasing these two or one at a time at a regular retailer and as long as I take them out of the device while storing them for an extended time, they seem to hold up rather well.

Thank you

I had a hard time finding these little batteries - until I thought to check Amazon! Tiny batteries for my tiny flashlights that fit on key rings - perfect! These came well wrapped, good packaging, and in perfect condition. A nice, long shelf life of a couple years that I appreciate, and they work great! Nice, bright illumination with no flickering from the lights. Best value I've found on small size batteries for any use! Delivery was also immediate.

You must purchase so many & use so few at a time. Most are outdated & dead by the time you need again.

Used one battery to replace old one - worked only for 2 days, then watch stopped. Open again, check voltage -dropped to 1.25V from 1.52V before. Use magnified glass and found some oxidation on the battery. Replaced with another one -so far so good. Should be good for at least 2 years says on the package...But price is really good.

Battery arrived in a timely manner and seem to be performing well.

Works well but would prefer to get maybe 5 in a pack. Only needed 3 for each of my watches and will last about 2 years or a little longer and by the time I need more, don't know if they well be any good.

Bonne batterie

Received the batteries today, and they worked perfectly with my watch. Plus, there's enough of them to last me for quite a few years, way less expensive than taking the watch to a shop at the mall to replace the batteries. Thanks!
