CR2032 3.0 Volt Long Lasting Lithium Coin Cell Batteries in Child Resistant, Standards Based Packaging, 10 Pack

TL;DR: Reliable CR2032 batteries from a trusted brand, with good longevity and fair pricing for a 10 pack. I use CR2032 cells for a mix of devices: key fobs, small remotes, bike sensors, and a couple of bathroom scales. Over time I have found that brand matters with coin cells, and this Panasonic pack has been consistently dependable. Every battery I have used so far has registered at full voltage out of the package and brought dormant devices back to life without issues. Longevity is where cheaper, no name cells often disappoint, but these have held up well. Key fobs and remotes that used to need frequent replacements with generic batteries now run for much longer stretches when I use these. Obviously exact life depends on the device and usage, yet the pattern has been measurably better in my household. This is only an opinion, not objective truth, but it matches what I would expect from a well known manufacturer. I also appreciate the packaging. The child resistant card is not impossible to open, but it requires deliberate scissor cuts, which adds a layer of safety for homes with children or pets. The individual blisters help keep unused cells protected from accidental contact and shorting in a drawer. For storage, that is a meaningful detail. Value wise, a 10 pack at this price point makes sense. You pay a bit more than the very cheapest options, but when you factor in the reduced hassle of premature failures, I see it as good long term value from a reputable brand. Long battery life, super easy to install. Great power. Helps my AirTags, and I’m sure would make a lightbulb bright if needed. Thank you for reading my review here, I try to be helpful.

These are good batteries at a good price. They fit the way they are supposed to and last about as long as you would expect. The new batteries seem to keep their charge if you don't use them for several years.

Great lasting batteries without the high price. Pick these up to have when you need them. Long shelf life too!

These are a great deal. Our alarm sensors on our doors and windows use these and some have lasted three years. The system tells us when the batteries are dead, so we know they’re still good. The packaging is a bit of a challenge though. Hence the four stars.

These batteries work well and hopefully will last a long time,” I like that they are a name brand.

I’ve been using these Panasonic batteries for car key fobs, Apple Air Tags, and other devices that call for this size battery. I’ve noticed no difference in performance/longevity between these brand name batteries and other higher priced name brand batteries. Choose these batteries without compromising quality and save yourself some money.

We live in a complicated world ... there is so much to know and it's hard to always have the information you need to make a good purchasing choice. Let me take you through my process. * Quality - I am always going to choose quality. If I choose a cheaper battery that doesn't last as long, I just don't want to replace it over and over. Panasonic has been a great brand for me in audio gear, DVD players, and yes, batteries. * Power - Not all CR2032's have the same power! Without knowing the power, you can't compare price. These are 225mAh rated. Some of the less expensive ones are as low as 150mAh. You don't need to be an electrical engineer to understand these numbers. These Panasonic's have 50% more power than a 150mAh battery. Some of the batteries available DO NOT have the mAh information listed - I would not touch those. * Storage Life - In my pic's you'll see a shot of the back and see that this 10-pack I just bought is, "best before" 05/2033. That's almost 8 years from now - that is excellent. * Packaging - These batteries are packaged to be safe to protect children, but an adult can easily get to them. That's important to me. An easy 5 Stars for a really great battery at a really great price.

High quality CR2032 battery that won’t let you down! Been using in my Key Fobs, Garage Door Openers, AirTags for the last several years. Best bang for your buck!
