Rated 1 out of 5 by Christopher from Leaking I've had to clean 4 Christmas candles that I stored last year because the batteries leaked badly. Apparently I can no longer leave Duracell batteries inside my electronic devices. On top of that, today, I had to throw away a little clock that I had for over 10 years that I had sitting on a shelve. It had 2 Duracell batteries inside. I immediately checked an emergency light that I have sitting in the corner for a just-in-case scenario and sure enough I found yet another battery leaking inside. Fortunately it did not too badly yet. I will NEVER purchase a Duracell product anymore unless I utterly have to. Duracell is not what it used to be anymore.

Rated 1 out of 5 by Friscobilly from AAA Batteries dated 2023 are corroding ! I generally use Duracell for all my battery needs and am pleased with their performance. However the AAA with the 2023 date are corroding at a fast rate. I became aware of this when I went to replace the batteries in one of my flashlights and found them very corroded. When I got my spare batteries I found that the whole box had corroded! I then noticed that both the batteries in the flash light and the box were both 2023. I then checked every thing else that I used AAA's for and found they were all corroding to some degree. I did find one that was dated 2016 and while it was dead, there was no sign of corrosion. So it must just be a problem with the 2023's.

Rated 1 out of 5 by JamesKastner from HAVE USED A LIFETIME and now shopping for another Since a kid, my DAD swore by these (Hurricane dependable in New Orleans.) Now they are not as good. They rupture too easily in warm climates. Used to have on shelf IN LIGHT or whatever for YEARS w/o problems. Now after a year you can expect leaking and destroying your light. They have destroyed 2 "D" cell MAGlights (NOT CHEAP) and some "AA" & "AAA" lights and remote control units ... My brother still in NOLA is having same issue so this is not just a "HOT & DRY" problem! IT IS A REDUCED SHIELDING PROBLEM TO CUT PRODUCTION COSTS! FED UP & going to another product. Starting to explore Delco & Energizer and some recharge units.

Rated 1 out of 5 by Firvo from Batteries burn nicely finished wood when they leak Two times now I have uncluttered my wife's beautiful maple hutch to find leaking batteries that had been set aside and underneath, in the shape of the batteries, the finish burned off. Now we don't monkey around, even partially dispensed batteries go in the trash. Don't know why they are always Duracell but it seems to be the case. Picture shows damage to hutch and a bin of partially dispensed batteries that were stored for future use. Note the brand and the fact that virtually all of them have leaked. I do not experience this with other batteries, even store brands. Time to remove all Duracell batteries and move to Energizer.

Rated 1 out of 5 by imillard from Having seroius doubts This is the second time that Duracell has let me down. The first time it was a 9-volt battery that in a smoke detector, that died so quickly and completely that the detector didn't have a chance to give a low battery warning beep. And the battery was only 6 weeks old. Now another 9-volt copper top battery has failed. It was being used as a backup battery for a digital alarm clock. This time the bottom of the battery blew out. The contents expanded until the top was deformed and the guts were pushed out of the bottom of the metal housing. So I'm having serious doubts regarding the quality of the copper top products. I certainly can't depend on these batteries for critical situations, such as smoke detectors.

Rated 1 out of 5 by tscii from Durcell Quality Control is in decline! Being a grandparent I have purchased countless Duracell AA and AAA batteries over the years mostly from Costco for the grand kids and their toys! In the last 5-6 years I've noticed that these batteries are having a leaking issue and it's getting worse. At first it was just one or two here and there and the problem was tolerable but lately I'm have to replace clock mechanisms, PC mouse, flashlights etc. on a more frequent basis. I checked a small sample of all the dead batteries I'm going to recycle and about 10%-15% of the ones I have are leaking. And looking at your own reviews from others it seems in the ball park. PLEASE FIX THIS OR I'LL BE FORCED TO GO BACK TO EVERYREADY!! THANKS!

Rated 1 out of 5 by Ensign from Leaking and corrosion issues I have purchased and used Duracell batteries all my life on the premise that paying a little extra I could get a quality product. I never had a problem with corrosion ever. Many times batteries would be in use for years without leakage. Then I noticed that Duracell batteries I was using came from China and I also took notice to excessive leaking and corrosion, often when the batteries had only been in use a short time. Often the leaking batteries had dates for shelf life for years. They have not only ruined ordinary flashlights but also expensive cameras, remotes, computer equipment, etc. I will now be changing to another brand any brand will be better than Duracell.

Rated 2 out of 5 by Tommy from Does Duracell actually back the 10 year guarantee? These batteries are not that leak proof. I heard the ones in my TV remote bubbling last night and I opened the battery compartment to find a clear liquid coming out of the battery. I went to replace the batteries and found most of the ones left in the package had already bulged and crystallized. The expiry date for these batteries are supposed to be 2023 and they were stored at room temperature inside a living room. Does Duracell actually back their 10 year guarantee? I've had Duracell batteries leak before, but I thought these new ones would fair better.
