Duracell Coppertop AAA Battery, Long Lasting Triple A Batteries, 20 Pack

Bought within the past month - went to use and had leaked / corroded in package. Duracell quality is non existent - this has happened a couple times and I keep giving benefit of the doubt as it used to be a great product - DO NOT BUY UNLESS YOU WANT TO RUIN SOMETHING!!!!!!!!!

Bought them about six years ago, and left them in my bedroom when I moved out for university. Thought they'd be fine because of the 10 year guarantee. Moved back recently and they have all leaked or broken. Don't pay the extra money for this brand, it's nothing special.

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.
