PKCELL 20-Pack CR2032 Batteries Compatible with Airtag 2032 Lithium Battery CR 2032 3 Volt Coin Battery, Long Lasting Power, Mercury-Free

How many times has a device needed a new battery, and that battery happened to be a CR2032, but I did not happen to have any of those around? Way too many to count, I'm afraid. I decided to take action and stocked up on CR2032 batteries by getting this product. They are functioning effectively in a number of devices, and I still have plenty in reserve for future replacements. At last, now I can relax.....

It’s that time of the year again when I have to swap out the batteries in my Apple Air Tags. The Air Tags don’t really get that much of a workout, and the batteries would probably still keep powering the little devices for a while, but you don’t want them to fail at just the wrong time – like when your tagged suitcase doesn’t show up on the airport carousel. So, I follow the manufacturer guidance and put in fresh batteries each year. That means I need to keep fresh batteries on hand.Just as when I buy dairy products, when I purchase a package of batteries, I check the “use by” date. The PKCell CR2032 3V lithium battery product description says “5-Year Shlef [sic] Life,” and the sleeve I received is marked “Best Before 2029-12.” So, my concerns about getting batteries through the mail were eased. I like the way each battery is individually sealed in the sleeve, so that if one should happen to leak, the others will not be contaminated. These should last me for a while.

Excellent set of batteries. These are extremely reasonably priced and work well.

These are good batteries, but not the best. I used one in an air pump, and it was already showing a decrease in battery after only a little bit of use. I guess it's a you-get-what-you-pay-for situation, but I guess these make up for the quality in quantity.

These PKCELL CR2032 8-pack batteries and an excellent value. For what you would normally pay for one battery, you get 8! I tested 2 of them on arrival and both batteries registered a strong 3.2 volts, the same as the name brand batteries I have purchased before. Their shelf life is equally as long as the name brands - mine show a shelf life good through December 2029, which is more than 5 years from today's date. I use these batteries in numerous items such as my Ring alarm sensors, fan remote controls and others. They fir perfectly as the OEM batteries and are working just as well.

These coin batteries can be quite expensive when bought individually, so this 8 pack is a good deal if you need more of them. I have a handful of bluetooth temperature sensors scattered throughout my house that need replacement batteries regularly and these are a perfect solution. They appear to be of equal quality to other coin batteries I've purchased.

These batteries are commonly used in key fobs and calculators. They are listed as 3 volts. I checked 2 of the 8 that I received with a multimeter before I installed them, and they were both over 3.3 volts. I did not check the other 6 because I didn't want to have them loose from the packaging. Fully charged and they both worked in my harley key fobs. Regular price works out to 75 cents each, on sale for $3.99 drops it to 50 cents a battery. That's a big savings over name brands that charge that much or more for 1 or 2.

These batteries are a common size that I frequently need for items, such as my ceiling fan remotes. Their price for eight is comparable to the cost of two name brand batteries. I tested them on my battery tester and they maxed out the meter so I’m expecting them to work just fine. The minimal packaging is easy to cut and frustration-free. Overall, highly satisfied with this product!
