The first time I bought 2 of these batteries they lasted a couple of years in an outdoor temperature sending unit that normally used up normal batteries every couple of months. I purchased a pack of 18 that arrived in early October 2023 and most of the ones I've used have only lasted a couple of weeks in things like TV remotes and other things that a normal Duracell copper top battery would work in for up to a year.

Have purchased these many times. Last few times quality has gone down. Lasting less time in all devices. They have not last 1 month this time. Not worth the cost at this point. Our device tells us the battery levels/tests battery. Brand new batteries are getting no charge. Pathetic.

Great price and size.

Great product

Some not good

Long lasting power

Good deal.

Love them

Kinda expensive compared to regular batteries BUT they last a good while in my cameras

Arrived on time and in excellent condition. Great product.
