Duracell Coppertop Duralock batteries are prone to leaking battery fluid during normal use, a recent deceptive marketing class act lawsuit claims.
Plaintiffs Lauren Carlson and Jamal Yusuf, both of Massachusetts, filed their Duracell class action lawsuit in a Massachusetts federal court on Nov. 19 against Duracell makers The Gillette Company and The Proctor & Gamble Company.
“Plaintiffs allege that Defendants concealed and misrepresented material facts concerning potential battery leakage during the intended use of their Duracell Batteries,” the explain in their Duracell Batteries class action lawsuit.
Duracell announced in a June 2012 press release that it would be launching batteries that came with “Duralock Power Preserve Technology.” These batteries would have a “Duralock ring” marked on them and would come with a ten year guarantee in storage, not while being used.
This 10 year guarantee was marked prominently on Duracell Coppertop packaging for AA and AAA size batteries.
The Duralock batteries were also part of an advertising campaign, which included both radio and television ads.
“On each of the Duracell Batteries, Defendants placed a date ten years in the future to affirmatively represent the date that the battery is guaranteed not to fail,” the Duracell Batteries class action lawsuit states.
“Nowhere on the packaging of the Duracell Batteries is the disclosure that the batteries may leak when used in a normal and expected manner,” it adds.
However, Carlson and Yusuf allege that they do “leak even when used in a normal and expected manner.”
They also allege that Gillette and Proctor & Gamble “conspicuously failed to disclose that the Duracell Batteries leak when not in use and the leakage can damage any device that the batteries are stored in.”
In addition, the “defendants’ glaring omission that the batteries can leak and ruin electronic devices would, and did, mislead reasonable consumers,” they allege.
According to Carlson and Yusuf, the Duracell makers “had knowledge of the problem of leakage in their AA and AAA sized batteries under normal conditions of use intended by Defendants.”
The Massachusetts’ plaintiffs claim that “numerous complaints” were “filed directly with defendants by showing dates throughout the class period showing a leakage problem.”
They further allege that Gillette and Proctor & Gamble relied on the fact that most consumers don’t put a lot of thought into their batteries and “withheld critical information in order to increase sales and/or their market share.”
The plaintiffs claim that they did rely on the advertising campaign when purchasing Duracell Batteries with the 10 year guarantee and “believed that the batteries purchased would not fail for ten years.”
They are proposing a class that includes “all purchasers in Massachusetts who bought Duracell Coppertop AA and AAA batteries with Duralock beginning June 1, 2012 throughout the date of notice.”
Carlson and Yusuf are charging the defendants with breach of implied warranty of fitness for a particular purpose and unjust enrichment.
The plaintiffs are represented by Erica Mirabella of Mirabella Law, LLC, by Richard Barrett and Barrett J. Clisby of Barrett J. Clisby PLLC, by Dewitt Lovelace and Valierie Lauro Nettles of Lovelace and Associates, PA, by Charles Barret of Charles Barrett, PC, by Thomas Thrash of Thrash Law Firm, PA, Ben Pierce Gore of Pratt & Associates, by Charles LaDuca and Taylor Asen of Cuneo Gilbert & LaDuca, LLP.
The Duracell Batteries False Advertising Class Action Lawsuit is Lauren Carlson, et al. v. The Gillette Company, et al., Case No. 1:14-cv-14201, in the U.S. District Court for the District of Massachusetts.
UPDATE: The Duracell battery class action lawsuit was dismissed on Oct. 21, 2015.

I bought a big pkg of them at Sam’s Club about 3 months ago that had the peel top containers. I had two AAs in my TV remote and they puked in there and screwed it up. Several of them are still in the containers and are leaking.
I sent an email with pictures to them and they have never replied. I was at Sam’s yesterday and they no longer sell them. Energizers now.
It makes me mad that they didn’t even repsond to my email.
Never again.
10/20/20 I now have 3 more battery powered items (2 flashed lights & 1 Apple Track Pad) that no longer work due to the batteries leaking.
This is far from the first time that I have been unable to even open the battery compartments on various items due to battery leakage.
Since this started happening I began to register which batteries I was putting into the powered items.
I have even found that the batteries leak when my items still work, so its not like they have just been left untouched for months & leak under those circumstances.
I have always bought large packs of Duracell batteries so I am 100% sure that is what is in the units as I never bought anything else other than Duracell batteries.
The Apple Track Pad’s battery compartment can be easily opened using a quarter to unscrew the end cap, however on this occasion I was unable to open it like this.
I then tried to open it by clamping a quarter into a Jaw Horse & rotating the Track Pack on top of the quarter.
After trying to undo the battery compartment it would not unscrew & I actually bent both the quarter & the Track Pad.
I then tried to access the battery compartments in both Mag flash lights & neither would open by unscrewing the end caps that hold the batteries in place.
Again using the Jaw Horse & clamping the body of the Flash Lights in place, I tried with a wrench to unscrew the end caps.
Neither would move at all.
I have since cut one of the Mag lights & the Apple Track Pad open to confirm that they are indeed Duracell batteries in there that have leaked.
Duracell batteries have rendered hundreds of dollars worth of my portable electronic equipment useless.
If there is an ongoing lawsuit against “Duracell’ for manufacturing & selling their defective products I would love to know about it, as I will have no hesitation in participating in it to retrieve the money that they have cost me.
Like other writers I used to trust Duracell, but they have obviously gone for cutting costs & producing sub standard merchandise.
I hope that they can be held accountable for this disgraceful situation.
I or my direct family will never buy Duracell batteries again until they reimbursed us for the damage that they have caused & will guarantee that they will stop manufacturing these sub standard batteries.
As most other posts have stated, Duracell batteries are not the same reliable batteries they use to be. Just found leaking AAA Duracell batteries for the second time in three months. Dated either 2024 or 2025. Ruined two premium LED flashlights so not happy. After using nothing but Duracell for the last 30+ years its time to switch to another brand. Duracell buyers beware!!
yes my desk draw cover with leaking batteries .. 16 case shot AA.. purchased at Sams club
Wow – the comments match my experience over the past month. Have not had issues with Duracell batteries for years. As a scout Master – with many scouts and many camping trips with dozens and dozens of battery operated devices (flash lights, camp lights, etc) I buy batteries by the case (well boxes of 36). But these Mar to Dec 2025 labeled Duracell Duralock AAA batteries are the WORST. Besides all of the Harbor Freight flashlights, I had them in Wireless Keyboard, Mouse, remote controls, TI Calculator, wireless speaker box, and a wall clock (so far) that are leaking. Help!
I have brand new ,unopened duracell batteries that I purchased 30-days ago from a retail store and I opened them today and half of them are already corroded. the manufacture date says they were made in 2019, so they did sit in a warehouse for 6+ months, but that is normal for any mass produced product.

Duracell leak even before. They leave their package! These are not the same Duracell’s they used to be.
I too have had many devices ruined by leaking Duracell Batteries. I will never buy them again. This has been going on for years with no statements or recalls by Duracell.
2Nd purchase of what we were always lead to believe, these were the best. There junk. In for not very long & leaked, have acid within battery compartment. Buy dollar store batteries. They seem better & far less costs.
That duralock technology seems not working, the battery leak damaged my microsoft wedge keyboard. I’ve never heard battery leakage these days, even a very low cost battery I’ve used frequently never leak.
i have had numerous duracell battery’s leak .—advice remove all duracell battery’s and bin them where duracell should have put them in the first place ,they are not addressing the problem of an inferior product
I agree with you, horrible product
I’ve had numerous devices ruined with the Duracell alkaline batteries without the devices even being used, sitting in my house over around a 3 month period.
I will never buy them again.
had 2024 aaa duracell batteries leak in a tv remote that was still in use. no more duracell!
Mine is a December 2024 battery also, these people don’t care.
