A package of Duracell AAA Coppertop cells guaranteed for 10 years. All of the cells have leaked electrolyte (November 2025). Ten years would have been December 2025, as shown in the lower part of the rightmost battery.

Well, they didn't make it to 10 years... And I didn't keep my original purchase receipt, so I can't make a warranty claim...
(the lower part of the rightmost battery shows the DEC 2025 code).
