Duracell Coppertop Alkaline AAA Batteries, 12 Count

I have bought Duracell batteries for decades. They always outlasted other brands and never had leaking or corrosion problems. The last package I bought, AAAs "good until 2023", are corroding in the package and in everything I've used them in. I don't have time to mess with this. It's time to use a different brand.

I was a stalwart Duracell customer for decades. Recently, however, I have had so much tool damage from Duracell leaking batteries that I gave up and went with the rabbit competitor, much less leakage. At first I figured it was a bad batch/bad year. Continued problems even sitting in storage, under perfect conditions convinced me otherwise. The company I manage has also switched entirely to different brands, with better results.

See photos attached. 1. In the package, batteries that have a 10yr warranty and expire 2022, have leaked by 2019. 2. In my Bose headphones case, reserve battery with expiration date Dec 2024 leaked (damaging case). For future reference, this post is from April 1, 2020 (and not an April's fools joke)

I live in tornado alley, so batteries are a life necessity, I check my batteries every Spring and I have had more stuff ruined by Duracell batteries than all other brands put together. I buy different manufactures because I am aware that their could be manufacturing defects in a particular lot, but Duracell is consistent in leaky batteries. Not to mention that every year I throw away Duracell batteries from storage that are 2-3 years short of their shelf life.

Ive been an avid fan of duracell till today Im going threw my emergency crates and checked over my 10 years guarantee batteries..ALL 5 packages of my AAA were toast,corroded and leaking, and 50+% of my AA 's were done for also.. they were maximum 7 years old. Very Disappointing.. I will be getting a hold of Duracell.
