12 Duracell DL2032 Duralock Lithium Batteries Cell Button Electronics (2x6)

I trust Duracell batteries. This seller is trustworthy. I would buy from this seller again because they stand behind the products they sell. I purchased the DL2032 and that is what I expect to recieve.

These batteries solved the problem of the system not recognizing air tags. Everything worked as original when programming the air tags. Very pleased.

I'm accepting that Duracell claims for quality are correct and these are very good cells. They are very concerned about little kids swallowing these cells and make the packaging child-proof. You will need a pair of scissors to get the cell out of the package. Really, the packaging is damn near adult-proof. They also put a bittering agent in a ring on the negative pole of the cell. This is exactly where Apple Air Tags have a contact. You can see this in the picture. Kudos to me for this picture. That insulating ring is invisible to the naked eye unless the lighting is just right. This ring is easily removed with fine sandpaper such as 400 Wet-and-Dry, or finer. If your AirTag does not beep, you need to sand the negative side a little bit more until you get a good contact. Clean the cell with a wipe to ensure no cell draining contamination is left. I took away one star, as Duracell should warn people about the AirTag problem and the insulating ring on the packaging. Kudos to them about making this cell as child-proof as possible.

Lasted as long as I would have expected to. Came an original packaging and was cheap cheaper than the big warehouse stores.

The bitter coating on these batteries makes them unoperable. I don't know why, but they simply do not work in multiple different home sensors I've tried. Went to the website for the devices and they confirm that they wont work with batteries with the coating. Duracell needs to come up with something better. I would think the kevlar packaging they use would suffice. You show me a baby that can get through that packaging and I'll show you a baby that a whole mouthful of batteries wouldnt phase.
