Almost ruined my camera flash.

I had four in my external Nikon external flash. Stored in my closet. They corroded and almost ruined my flash. Two of them were very hard to get out. In comparison I had another flash stored in the same place with generic batteries and they were fine.
I've used Duracell exclusively for many years without much issue. lately (last year or so) every device I put these in has been destroyed due to battery leakage; flashlights, voltage tester, label printer on and on. until the problem is fixed I'm using another brand, energizer perhaps
I bought a pack of 32 AAA's 1 year ago and contrary to the label it leaks. It leaked with the packaging and in my flashlight. The acid ruined the connectors on the flashlight. Beware of the 10 year leak proof guarantee - it LEAKS!!!
2025 Duralock AA & AAA batteries are evidently made in China, seems they don't last even a year and corrode even when sitting in the container! (see pic. I am about to throw away all my last batch of 2025 Duracell batteries and Energizers...
I have used Duracell for many, many, happy long years. But a recent batch seems to be defective. I had a big pack of AA and a big pack of AAA, both dated 2022, and all the batteries in each pack broke open and leaked - one set of AAA leaked within 6 months of being put into a TV remote!!!!! It's not just the fact that I paid a premium for the Duracell brand; it's BATTERY ACID that's being leaked here, and I've had 2 remotes ruined as well as other electronic equipment that most often cannot be repaired and has to be replaced.
