Duracell® Coppertop AAA Alkaline Batteries, Pack Of 6

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.

I have bought Duracell Coppertop Alkaline batteries for years, paying more than for other brands. Lately they have an annoying habit of leaking, even while in their original packaging and well before expiration dates. I have a lot of batteries I am going to throw out as I search for another brand. I have complained to the company, in response to which I have been asked a number of questions about original packaging and where and when I bought my batteries. I don't have all the information, only the batteries that have not expired but have leaked.

Leaking batteries are ruining my equipment. I was employed by the company that owned Duracell back in the 80's so I always was a fan. BUT, it seems lately I'm having more battery operated equipment ruined because of leaking battery acid. NOT A FAN ANYMORE.
