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.

Excelente

UPDATE 2025: After 4 years, we got the same warning from the car as described below. We have two fobs, so I had two batteries left from that 2021 purchase. I checked them with a voltmeter and both were still well above 3 volts! So I installed them and we're all good again. Wow. If you buy some today will they last 4 years? Who knows. But I'm impressed. The car issued a warning about the transponder ("immobilizer") key battery being low -- and there were two people in the car with keys! Which one? Figured we had to replace batteries in both. This item was available overnight from Amazon, which we needed due to upcoming important car trips. We noticed Amazon customers with inconsistent results on many similar batteries, so we got a 4-pack of these and another brand. NOTE Amazon was both the seller, not some third party. I chose these partly for that reason. Decided to try this pack first. Tested 2 for voltage. Both showed 3.17 volts, so we never opened the other pack! Then opened up the key fobs, and found that the car manufacturer had used Panasonic batteries identical to these. That was reassuring. The old batteries that we replaced both showed 2.86 volts, which doesn't seem all that low. Apparently the car is very sensitive about this -- most appliances, flashlights etc. would not mind 5% below the spec voltage. Obviously it will be important for these to last a while, so if there are problems in the future I'll come back and update this. For now, I would recommend these if you have a similar need.

(Panasonic CR2032 3.0 Volt Long Lasting Lithium Coin Cell Batteries in Child Resistant, Standards Based Packaging, 4 Pack / $6 at the time of ordering) There's a 10-pack that's a much better value if you go thru a lot of these batteries. I just needed this for my car's fob/remote. With an item like this, it's hard to tell if all the batteries are good because it'll take me years to go through all of them. But I can say that it did ship quickly, the packaging was sealed (like you would find in a store), and the expiration was April 2032. For this 4-pack, it was fairly priced for what I needed it for. Overall, good buy.

Great value

they work for what i need it to do

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.

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
