POWEROWL High Capacity CR2032 Battery (20-Pack) 3v Lithium Batteries, Leak-Free, Long Lasting Cr 2032

I use these for tea lights in a setting at work that needs a long lasting battery. These are remarkable in that they last longer than any other battery I've used, including famous big name brands. These are exactly the correct size and construction based on the calipers I keep at my desk. (Doesn't everybody have calipers at their desk?) Because the size is as expected, they slide right into place with no muss or fuss and that fit makes them compatible with several brands of tea lights I have on hand -- completely as expected. For what I paid these were a phenomenal value, and I'm hoping I will always be able to get these as my new go-to CR2032 battery. 5/5 stars, charged and ready!

work OK but life expectancy from previous order of same batteries was spotty. Nevertheless the price was right.

No issues with this purchase, batteries are long lasting. correct dimensions and fit nicely in my devices. I had no issue installing these batteries and the storage capacity seems accurate.

Powerful Little Batteries That Actually Deliver I bought this 15-pack of POWEROWL CR2025 lithium batteries mainly for car key fobs and small electronics like kitchen scales and remotes. For less than $7, you get a surprisingly solid supply—each battery individually sealed and neatly packaged, which makes storage and organization easy. Performance-wise, these are holding up well. I tested a few in my car remotes and digital thermometer, and all powered up instantly with strong, consistent output. The packaging says “10 years leak-free,” and while I obviously can’t confirm that yet, the tight seal and clean design inspire confidence. The voltage readings were right on spec at 3.0V fresh out of the pack, suggesting these haven’t been sitting on a shelf too long. They’re not rechargeable (nor should they be), but for a disposable coin cell they feel premium—especially compared to generic bulk brands that often arrive half-dead. I also appreciate that they list all the equivalent model numbers (CR2025, BR2025, LM2025, etc.), so compatibility is easy to check. One small gripe: the clamshell packaging is tougher than it needs to be—expect to need scissors. Also, while they’re great for remotes, watches, and scales, I wouldn’t count on them for very high-drain medical or camera devices. Bottom line: A dependable, affordable 15-pack of CR2025 batteries that perform as advertised and save you a small fortune compared to name brands. Perfect for key fobs, scales, and other everyday gadgets.

Perfect batteries to always keep in stock at home. They work in my car keys! I have kids and 4 cars that use this battery. Nice to have on hand.

The battery life of these are great despite the fact that they’re so cheap for 15 of them. So you doesn’t get your moneys worth out of it for not very much at all. They do fit into my O site SE green micro dot optic on my gun. The reason why I like this specific brand is because it allows you to buy so many at one time as you won’t need optic batteries for I’d say maybe four years or five years if long as long as you don’t shoot that often at the firing range but I’m about to start firing him more often at the firing range so I’d say the pack would last me more around a year.

If you're into PC building like we are, you know there is nothing more annoying than your CMOS battery dying right when you're trying to troubleshoot a BIOS issue. We picked up this Powerowl 20-pack, so we’d never have to make a midnight run to the drugstore for a single, overpriced battery again. These are 3V lithium and, honestly, they perform just as well as the big-name brands we used to buy. We’ve already swapped them into our garage door opener and our Apple AirTags, and they’ve been going strong for months with zero issues. The "leak-free" guarantee is a huge deal for us too — especially when we’re putting them into expensive electronics like a motherboard or a high-end digital scale. The packaging is great because they come in individual blister packs, so you don't have a bunch of loose batteries rolling around in your junk drawer. It’s a total "set it and forget it" purchase. For a student on a budget, getting 20 of these for what you’d normally pay for a 4-pack at the grocery store is a massive win. If you have a lot of small tech around the house, this is the most cost-effective way to keep everything powered up.

Okay batteries. Really bad packaging. So hard to open. 3 of the batteries were dead or died quickly which was disappointing. We used this to make STEM flashlights so I used all but 3 batteries since they weren’t working and it wasn’t helpful trying to open the package when I was in a rush.

هذا المنتج ممتاز وسرعه في التوصيل شكرا Thank you for the product

Very good product

The batteries are well packed and on initial usage appear good. Delivery was a little slow but that doesn't detract from the item itself.

And works as a battery. I have used them in my truck key fob, and apple airtags and they have worked without issue. So far so good, will update the review if they don't last as long as other ones.

Not sure what is up but my key fob eats batteries. Tried name brand and they too do not last so with these lasting just as long I am calling it a win.
