POWEROWL High Capacity CR1632 Battery (15-Pack) CR 1632 3v Lithium Batteries, 10 Years Leak-Free

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!

EDIT: The seller reached out to me and offered to make this good. Apparently "the recent implementation of child protection laws for coin series batteries, known as Reese's Law, by the US government prompted [them] to increase packaging costs to prevent any harm to children from accidental ingestion of batteries." Heck, I can't argue with that. I upped the rating to reflect that they were sympathetic and stand behind their product even if they're just trying to be safer. Original review left here for completeness: I bought this pack of CR2032 batteries fully expecting a simple transaction: I give you money, you give me tiny discs of power, and we both go on with our lives. What I did not expect was to enter into a 20-minute cage match with this Fort Knox of a blister pack. It's worse than those paper tamper covers on the brand name cocoa powders. Let me be clear, the batteries themselves seem fine. Once I finally liberated one, I got it installed and I assume it's quietly doing its happy little job in my key fob. But this packaging is just unreal. It has opinions... strong ones. It does NOT want you to have these batteries. It believes you are not worthy and is determined to prove you so. The front of the blister pack features these cheerful little scissor icons, practically winking at you like, “Just snip right here! It's easy!” That is a lie... a bald-faced, unapologetic, scheming, conniving, brazen, shameless LIE. Cutting there doesn’t open the package at all -- it just rearranges the problem into four smaller and harder ones because you've just snipped off any paper overhangs that you might be able to get a fingernail under. And then one little slip and boom -- you've got a sharp plastic corner under your nail. It's awful. Don't believe the scissor icons! Then there’s the back... and I feel like I'm having a trauma reaction here, so bear with me: It starts to peel, gives you hope, lets you think you’re making progress, and then it just separates into layers like one of those flaky biscuits. You peel one layer, and there’s another. And another. And then you have nothing to pull anymore that isn't somehow magically welded to the plastic, so you start in with the fingernails and then out come the tools... bigger and bigger tools. And then when you finally see metal from the back and you finally think "omg I'm there! I'm THERE!" you just get this heartbreaking realization that the batteries are entombed by yet ANOTHER layer of plastic on the back. It's maddening! I JUST NEED TO GET AT A BATTERY! PLEASE! Clearly someone in a boardroom or packaging design firm somewhere was having a really bad day ...or maybe they need to be working for a glue or security company somewhere. Maybe they're sitting back laughing at all of us. I dunno. I mean I finally got to a battery and all (with a box cutter, from the front, cutting uncomfortably close to the battery itself), but somehow I just feel like I lost the battle. There are so many batteries in this pack and after like 20 minutes I only managed to free a single one. I feel utterly defeated. So in conclusion: The batteries are fine once you successfully complete the escape room they’re packaged in. Five stars for the batteries. Zero stars for the packaging. May we never meet again.

Good quality. Good value. My husband bought these for something around the house. This type of battery is expensive. This is the best value he found, and they work great. Would buy again.

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.

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.

These Powerowl batteries are excellent for key fobs, rifle scopes, or other optics you have. I havnt had one leak yet and this is my second pack I have purchased. They fit perfectly as intended, so no issues there. I would highly recommend these to whomever was in the fence about this brand. They are fairly easy to get out of packaging if you know what you’re doing. Make battery replacement a breeze and save a few bucks while doing so.

Items work fine can't beat the price. Ship very quickly.

good value, fit perfect, too soon to rate battery life.

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

Decent quality and value. Having bought from different sellers have preference for individually packaged batteries as they seem to hold charge better. So far these are ok.

Great for all the fobs you use! GPSTags. Much better price than individual buy and I change my batteries regularly! Great find !!

Need a few of these for some electronic devices. 15 of them for the same price as getting 2 or 3 is a great deal.

Great price and very quick shipping.
