TESLA BUTTON LITHIUM BATTERIES, CR1220 Mercury free Lithium Cell Battery 3V, 7 Year Shelf Life, A Long-lasting, Leak-free, Suitable for flashlights, car keys, watches, key fobs, 5 count [Pack of 1]

Got these end of Feb 24 and the best before is May 25. They are listed as having a 7year shelf life. Save your money and buy the cheaper one's. I feel like i been mugged.

Given how many things you need button batteries for these days, I like to keep a good range of sizes available in the house and car. Normally I don't pay this sort of price for them, but if the claims made by Tesla regarding their longevity in use and their shelf life is true, then they're good value for money.All I can say at the moment is that the one I have in my small flashlight in the car is working well.

Good cost effective way to buy batteries, better than buying a single battery. The work fine.
