Panasonic 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.

I’ve been using Panasonic CR2032 3.0V lithium coin cell batteries exclusively in my key fobs, and they’ve been consistently reliable. A 10-pack may seem like more than you need, but with three cars (and two key fobs for each), it actually makes sense for me. It’s also much more affordable compared to dealership battery prices and labor costs. The batteries are well packaged and clearly marked with expiration dates, which gives me confidence they’re fresh. Installation is quick and easy, and they power up the key fobs immediately without any issues. What really stands out is their longevity. In my experience, each battery lasts about two to three years. Panasonic has a strong reputation for quality, and these CR2032 batteries live up to that standard. If you’re looking for dependable, long-lasting batteries for your key fobs, these are a safe and worthwhile choice.

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.

Many of my small electronics decided to die at the same time. My car key fob, a kitchen scale, and a garage door opener all gave up within a week. They all needed the same thing: a CR2032 battery. I decided to buy a pack to have on hand for the next wave of tiny electronic deaths. I chose these because the brand is familiar. The batteries arrived in what can only be described as Fort Knox packaging. The child-resistant claim is no joke. I needed a good pair of scissors and some determination to free one from its plastic prison. I suppose this is a good thing if you have curious toddlers around. It is less convenient when you just want to weigh some flour. I popped the new battery into my kitchen scale, and it came back to life instantly. I did the same for the key fob. It now works from across the parking lot again instead of just when I am touching the door handle. The batteries do what they are supposed to do. They provide 3 volts of power in a small, flat circle. They seem okay. It is hard to be too excited about a battery, but it is nice when they work.

These Panasonic CR2032 batteries are excellent! They work flawlessly with my AirTags and other devices that use 2032 batteries. The child-resistant packaging is a nice safety feature, and the batteries are long-lasting as advertised. Great price for a trusted brand—highly recommend for AirTags or any device that needs CR2032 batteries!

Works on my fobs. Fraction of cost compared to paying dealership.

We have lots of Air Tags because we have lots of stuff to lose. They are fantastic for keeping tracks of things, but the batteries do discharge. A quick pop off of the back, replace the battery, and we are on our way. These worked straight out of the package and that's about as much as I could have hoped for. Good price as well.

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

Long life, work well and better than cheaper alternatives. Only buy Panasonic now as they have decent life

This brand has good quality. The battery worked out of box. I had dead batteries out of box with other well known brand.

Works like a charm. No issue at all worked 1st time.

These batteries work well and this is the second time that I have ordered them

Great for car key batteries, they work better than the major brand as they seem to be slightly thicker giving a better contact. Had tried top brand batteries only to receive message that battery needs changing, looked up on google and was advised to use Panasonic, no problems since.
