DURACELL 2032 Lithium Coin Batteries (4 Pack) 3V, CR2032

I bought this Duracell lithium 4-pack specifically to replace the dead factory coin cells in my daily-use blood glucometer and our digital bathroom weighing scales, and am very happy with this purchase. Performance Breakdown: Build Quality & Safety: The physical construction of these batteries is excellent. A standout feature is the bitter-tasting ring coating on the back, which provides great peace of mind if you have small children or pets in the house. There is a little black sticker at the back of each battery. It is designed to alert parents to the extreme choking and internal burn hazard these batteries pose to infants and toddlers. You must peel it off: The sticker is made of non-conductive plastic. If you leave the sticker on when you put the battery into your device, it will completely block the electric current, as will the bitter coating if a device's internal terminal tabs happen to line up exactly where that clear, non-conductive bitter coating is placed; the device won't get any electricity and will not turn on. If this happens (as it did to me), you will need to scrub the battery clean with isopropyl alcohol to get a reliable electrical connection. Quick solution that works. The child-secure plastic packaging is exceptionally tough—you will definitely need a good pair of scissors to get them out. Real-World Power: Once installed, both devices powered up instantly with full battery indicators. My glucometer screen is noticeably crisper, and the Bluetooth syncing to my phone has been flawless. Unlike cheap generic brands that cause scales to throw intermittent "Low Batt" errors after a week, these have provided steady, uninterrupted voltage. Longevity: Having used Duracell coin cells in the past, they easily last 12+ months in low-drain devices. The 10-year shelf life is brilliant. There are many options on Amazon that claim years long shelf life, but have no specified manfacture date, without which, one can't tell how long the batteries have actually been sitting on a shelf. Duracel is very transparent and clearly shows the manufacture and expiration dates at the back of the packaging. Limitations: The Bitterant Coating Catch: As already mentioned, the child-safety bitterant coating can occasionally cause a connection issue in very specific devices. If your scale or glucometer has deeply recessed or flush terminal tabs, the coating can act as a minor insulator. so if your device doesn’t turn on immediately, again, simply wipe the back of the battery firmly with an alcohol prep pad to clear the residue, and it works perfectly. Except for this, I really cannot think of any other issue that needs to be pointed out. Final Verdict: this is a versatile, good quality product from a trusted brand and a premium, reliable choice for variety of electronic devices. The 4 pack at AROUND £ 5 is a good value for money. Definitely recommended.

I’m very pleased with this pack of lithium coin batteries. The longevity is excellent — they hold their charge for a long time, even in devices that are used daily. The brand feels reliable and well-made, giving confidence that these batteries won’t leak or fail prematurely. In terms of battery life, they clearly outperform cheaper alternatives I’ve tried, lasting months longer in items like key fobs, watches, and small electronics. That durability translates into great value for money, as I don’t have to replace them nearly as often. They’re easy to use and fit perfectly in all compatible devices, making them ideal for a wide range of uses, from remote controls to medical devices. Most importantly, the power output is consistent and strong, keeping devices running smoothly without sudden drops in performance. Overall, a dependable, high-quality battery that delivers excellent performance and is well worth the purchase.

Batteries last well good value for money

Does the job with a good battery life but doesn't taste nice at all. Terrible aftertaste and needed to wash mouth out.

Duracel. Great product, fair price. Shame the delivery driver delivered it to a Post Room for the Caravan site and canal boat dwellers so I eventually had to walk a qtr of a mile to retrive it.

As usual Duracell provide good quality and reliable batteries Correct fit And fair price

These Duracell CR2032 batteries are exactly what you'd expect from a well-known brand – reliable, long-lasting, and ready to go straight out of the packet. I've used them in a variety of devices, including key fobs, small electronics, and tracking accessories, and they've performed without any issues. The packaging is secure, which is particularly useful if you have children around, and the batteries themselves have a good shelf life, making it worth keeping a few spares on hand. They fit perfectly and provided immediate power to the devices I tested them in. Although cheaper alternatives are available, I've found branded coin cells tend to offer more consistent performance and better longevity, which helps avoid the inconvenience of frequent replacements. Overall, this is a dependable pack of CR2032 batteries from a trusted manufacturer. Ideal for AirTags, remote controls, fitness devices, key fobs, and the many other gadgets that rely on coin cell batteries.

Work as it must works. It tastes is very bad :)

Ce sont clairement les meilleures piles boutons que j'ai pu tester jusqu'à présent en matière de tenue sur la durée. Alors oui, elles sont un peu plus chères à l'achat que des marques bas de gamme, mais comme elles durent nettement plus longtemps, le calcul est vite fait et on s'y retrouve rapidement. Un choix fiable pour les appareils du quotidien !

J’ai acheté ces piles CR2032 principalement pour les utiliser dans mes Samsung Galaxy SmartTag, et elles remplissent parfaitement leur rôle. Elles fonctionnent parfaitement et offrent une autonomie excellente, ce qui est exactement ce que j’attends de ce type de pile pour un traceur qui doit rester fiable en permanence, sans qu'on ait souvent à se soucier de l'état de la batterie. Le pack de 4 est pratique pour en avoir toujours en stock. Duracell reste une valeur sûre, peut-être un peu plus chères que certaines marques génériques, mais pour un appareil comme un SmartTag, je préfère miser sur la fiabilité et la durée de vie.

Good for my every day use of remote and light's would recommend
