I don't see where anyone said "can't damage" in this thread. The closest might be me – who said: "I just dust off some crystals and the thing works again." So far, this has always been my experience over the last few decades
Then again, since your experience was with a flash – you might have suffered a more catastrophic leak than anything I have seen – I only use alkalines in fairly low drain devices like weather stations, remotes etc. A flash is an extreme current device. I don't use alkalines in those because of the performance limitations (ie most flashes cycle much faster on NiMH batteries) and I never leave batteries of any sort in flash units.
I know that this is a 6 or 7 month ago thread, but I have heard on YouTube that any Duracell batteries made after the 2000s will leak very fast, even while remaining inside their original packaging. This video on YouTube, titled “Big Name Batteries Stink” sums it up. Now, before the 2000s, Duracell was a reliable brand, with Energizer and Rayovac being the opposites, but after said decade, Energizer and Rayovac became reliable brands for batteries, with Duracell decreasing in quality. Energizer Holdings also now owns the Rayovac brand, as of 2019. Before then, the Rayovac brand was a subsidiary of Spectrum Brands Holdings, which in fact, was formed in 2005 as the successor to the Rayovac Corporation company. In addition, Eveready is a sub-label of Energizer Holdings.

Sorry, don't believe that at all. I still use Duracell as my primary battery for AA and AAA sizes. I have Duracell AA batteries in my outdoor weather station, and they're close to 3 years old and they're fine. I've never, ever had any name brand battery start leaking in the original packaging. For some of my uses, I have batteries over a year old still installed and working, obviously a low drain use situation. Someone made a YouTube video to get clicks.
I’ve always used Energizer as my primary battery, and I don’t recall seeing one leak.
I just threw away 4 Magnate’s that used AA battery’s. All had Duracells in them. They leaked so badly I couldn’t get them out. Ruined about $75 in flashlights. So I started looking through my remotes and found four of them that had leaky Duracell’s. I have noticed Duracells leaking more over the last,3-4 years but it is getting worse. They don’t all leak but enough that I have to keep my devices without batteries in them until I use the devices. No more Duracells for me. Just ordered some Energizers. They seem to stay leak proof.
It is also possible with the advent of geoengineering and the extensive use of more microwave energy for weather alteration and methane gas breakup in the atmosphere that the reflected energy from the ionosphere could be causing extensive gassing within the batteries causing them to leak. Also the metals and other substances being used for aerosols in the atmosphere are also getting into all devices and causing havoc with contacts in light fixtures, relays, power supplies, computers, and especially automotive or lawn and garden machinery where they are sitting in unconditioned air allowing it to penetrate into the works. Especially seems more prominent during the build up 2 days in advance of what the meteorologists call a cold front but is really not but a cold descent of particles that react with moisture to create extreme cold conditions. (Cite Ice nucleation patents).
ing to what I read on warranty support, You have to have a receipt and it is only good for 2 years from date of purchase. In my case I have damage in those Mr. Beams motion operated LED lights which worked fine for 5 years until suddenly they didn't any more. Upon taking them down to change batteries, found out the batteries had been leaking and caused damage to the foil on circit board and reflector assembly. One I was able to repair after cleaning and drying out. The other for a short while and having problems again.
Yes, I whole heartedly agree. Duracell AA batteries over the last three to five years have leaked in EVERY remote control as well as an very expensive ham antenna analyzer I've placed them in. I've not lost any equipment due to the leaking due to my handiness with a soldering iron and cleaning chemicals I have access to. I have replaced every Duracell AA battery I can find and i wound up throwing away about a dozen unused Duracell AAs because the crud that leaks out is SO caustic. I am DONE with Duracell AAs.
So how about this Duracell? Care to comment?
