CR2032 3V Lithium Battery(5pcs)-Coin & Button Cell for Apple Airtag/Car Remote/Key Fobs/Glucose Monitor/Candles/Watches/Scales/Doorbell/Intelligent Sensors/3Volt 2032 Battery Replacement

What can you really say about batteries? These CR2032s do exactly what they should – powered my Airtag and car fob straight away. Decent pack size, good value, and so far the life seems solid. Nothing flashy, just reliable power at a fair price.

Great bible for a teenager. Jesus words in red which is want I wanted. Great design. Haven’t tried the app yet but we will, great option to have

Batteries suitable for a car key. Somewhat cheaper than popping to a shop. I don't know how long they will last but I had no warning when my last battery was going to die.

Fast delivery. Exactly what I needed for my key fob. Great value for money and they work.

Just what i needed for my car key fob. These batteries are really for the use of calculators.

Great quality and delivery

Does the job just fine 👌🏻

Bought a pack of 6, used first 2 in my car key, worked well at the beginning but batteries ran out in 2 weeks. Changed an other 2, exact same thing happened, worked well for 2 weeks then batteries drained out again. Seems either this brand is not good or are very old batteries. Won’t buy again.

This battery seems to last longer than more popular brands. they work great on tea lights.

Good price for a bundle

Bought for key fob and kids toys. These don’t last. Key fob works only a few weeks per battery

As all sorts of electronic devices get smaller, use SMD components and generally require less power, their batteries tend to follow that trend. Of all the coin style batteries required for my use, the venerable CR2032 seems to be the most prevalent. It started with computer 'CMOS' batteries and, since, has spread to keychain flashlights, alarm sensors and who knows what. So, having a supply on hand is a good thing. Finding 30 of them at a reasonable price makes it rather easy to do. These have no expiration or best by date which is disappointing. Their resting voltage upon delivery was 3.33 volts. Seems normal for 3-volt Lithium batteries. They came in six retail packs of 5 batteries each. I deducted one star for the expiration date issue because, without one, supposedly "new" batteries can be 10 days old or 10 years old. Leaving the purchaser in the dark . . . Perhaps, literally.

I ordered these batteries to replace the one in my car remote which goes from 100-to-0 very fast. Even the most expensive brand name batteries last only for a couple of months for some reason. These have turned out OK so far -- the packaging gives a hint of higher quality than other really cheap batteries. I'll see how long they manage to last with my remote, and provide another update. In the meantime, the price is reasonable, and the initial impression is good...
