Panasonic CR2032 3.0 Volt Long Lasting Lithium Coin Cell Batteries in Child Resistant, Standards Based Packaging, 4-Battery Pack

Picked these up for my car key fob (Audi A5 & Honda Civic) and they worked right out of the pack (as always). Panasonic is a reliable brand for this kind of thing and the price is fair for a 4-pack. Packaging is slightly hard to open, but no complaints otherwise.

Wouldn’t you know? My diabetes test kit uses two of these batteries and my primary kit and secondary/back up batteries all died within two days of each other! I would’ve ordered two sets because I want to put a fresh battery in each of my car fobs, which used the same lithium battery. Good price and works well! The batteries are about the size of a dime and easy to replace the old batteries with a little patient. I can’t tell you about battery life if I haven’t used them for more than a few weeks so if I somehow run across this review, I will update, but I expect they will still be working just fine.

Works very well

solid battery, used for my car key. Works for now, will have to see how long it lasts

They do not have the bitter coating that many devices have trouble with. As far as child safety, the package is more than difficult enough to deter a child. Almost too difficult, but I realize they need to protect battery hungry regrets. Long shelf life and decent price.

Worked very well with AirTag!

The dealer wants $10.00 to replace the key fob battery. For less than that I purchased a four pack of batteries and exchanging the old battery was very easy. Thanks!

Compré este paquete para los controles remotos del auto, llaves inteligentes y otro dispositivos electrónicos, y funcionan de maravilla. Panasonic es garantía de que no se van a sulfatar ni a dañar tus dispositivos electrónicos. Tienen una excelente fecha de caducidad a largo plazo, por lo que vale muchísimo la pena tener el paquete de repuesto guardado.

Bon produit

No duran nada, la usé solo una vez en una báscula, la segunda vez ya no funcionaba

Alles super 👍

I’ve learned the hard way that not all CR2032 batteries work well with Apple AirTags—some die too fast or don’t fit quite right. But these Panasonic CR2032 3V Lithium Coin Batteries are flawless. They slide right in, deliver consistent power, and last as long as expected. Why I stick with Panasonic: ✔ AirTag-Compatible – No fitment issues or early failures (unlike cheaper brands I’ve tried). ✔ Long-Lasting Power – Holds up for months in my frequently used AirTags. ✔ Trusted Quality – Panasonic’s reliability is worth the slight premium over generic batteries.

Fantastic
