Duracell Coppertop AA Alkaline Batteries, 20 Count

To be fair I don't remember when I bought these batteries but they claim to be good until 2024 and have spent their entire existence inside my air conditioned home. I have 7 AAA's that won't work in a TV remote. There are 4 still working batteries that came out of the box but the last unused 7 were DOA. The rest of the batteries worked as expected over the past year(s).

Since the 70's I sold/used Duracell, they were the best battery and never corroded. Now any time I open a unit with batteries in it for even a reasonably long time, CORROSION and the damage to the unit that corrosion does. I will no longer recommend duracell, they have lost their way (PS: this battery said it was good until 2023)
