Duracell Coppertop Alkaline Batteries, AA

Duracell has always been my choice of battery to use. Unfortunately, in the last 6 months, I have had 2 unopened packages with an expiry date 2025, corrode. At first I thought it was how I stored them in the package. But that isn't the case. I'm keeping them in a cool, dry place. Then, a couple of batteries I just put in a remote a month ago, leaked and there was a white powdery dust inside the cover of my remote, with some kind of leakage down inside where the batteries were. Brand new batteries did this! These aren't small packs of batteries I am buying either. I'm going to a club and buying the large packs of batteries. Guess I'll be switching. I can't have unopened batteries corroding or new batteries leaking.

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 have been using Duracell batteries for many.. many years and up until the last 5 or so years had no real problems. Lately I've been getting cells that claim to be good for several years of storage, but tend to leak new in the package or make a mess of expensive equipment because of leaking. These are not just the regular copper tops, but also the "commercial" grade red tops as well. I've been switching over to the Panasonic "Eneloop" rechargeables with remarkable success and long term storage. I guess Panasonic have actually been improving their products over the years rather than just claiming to with different packaging. If you want to buy these batteries cheaper than the MSRP, buy the Costco Kirkland brand.. Duracell makes them! Just without the copper top shrink wrap label.. they tend to leak just as much though :(

I have at least 3 dozen each of AA and AAA batteries, all with at least 5 years left before the expiration date printed on the cells. I throw some out every month for premature failure due to leaking, some in storage and some installed in devices where the leaking induces corrosion on device battery terminals. I am about to throw them all out in favor of another brand.

Over the years I've used Duracell products and was real happy with them. I've noticed that recently these batteries tend to leak. I see quality has gone out the door and cheap practices have taken place. You should change your name from Duracell to Duraleak.
