Clearout Deal

Just had a maglite flashlight destroyed from leaking Copper Top battery. Just using in non extreme environment. Very diapointing. Third occurane of an issue in lat 8 years. It may be time to try a new brand. I used to excusively use Duracell batteries but not sure this is smart to do anymore.

Leaking Copper Top Kills Another Flashlight

duracell.com

I do not normally write online reviews but decided to in this case to warn people of the almost 100 percent probability that the Duracell AA or AAA will leak. In browsing thru the existing reviews it is apparent that I am not the only one to have issues with these batteries. The C and D batteries do not seem to have the same problem.

Guranteed to leak

Shawnna

I've always been a "find-a-brand-that-works-and-stick-to-it" type of girl. Duracell has ALWAYS been my battery of choice because it USED to always be more reliable and last the longest...especially in electronics. NOW??? Forget it.

Ever since they introduced this (insert expletive here) DuraLock "technology", nothing lasts long at all. I used to go for at least 6 months of regular every-day usage of my wireless mouse. Now? Less than a month. First pair of DuraLock batteries I put in my wireless indoor/outdoor thermometer ruined the electronics...certain parts don't work right anymore and it's not due to leakage. LUCKILY, I haven't had any leakage that I have found, but I think it's only because I've had to replace them due to them being dead before they had the opportunity to leak.

My daughter's play cash register (which she doesn't even use a lot), doesn't work more than 2 week...and doesn't even work correctly right after installing new ones. And it's NOT a problem with the toy as other batteries make it work right.

Duracell REALLY needs to go back to their tried and true formula...not this manure that they're trying to feed us. Luckily, I can still find slightly older batteries (but still good and NON-DuraLock) in some Mom & Pop stores locally.

If they don't fix this, I may have to go hopping down the "bunny" trail...

DuraLock has ruined your reputation

I've used Duracell for years. Last year the one in my keyless garage door opener died after 8 years of service. So I purchased and installed a 9V Duracell Duralock in September of 2012. Today, it died and I was locked out after dropping off my car for repair. Later, on checking with a voltmeter, the battery read near zero. I checked the last one from the same package and it read well over 9V. I put it in and the opener now works. But I wonder for how long. And I have a couple in smoke detectors. A single failure (never before with Duracell)? Or a pattern. Other reviews make it look like a pattern. I will reconsider my commitment to Duracell.

Disappointment

Hi I am doing a science project for school on the longest lasting battery. I am testing Duracell Coppertop, Energizer Ultimate Lithium, Eveready SUPER HEAVY DUTY, and Panasonic batteries. Congradulations, because Duracell Coppertop is shining the brightest so far. The others are slowly dying, but your brand is strong and is persevering the constant running of the flashlight.

Science Project on Battery Quality

I am very disgusted with the old and the new Duralock batteries and will never buy again!!! On the coldest morning we woke up to no heat, why? because our Duracell AA battery leaked inside our digital thermostat, therefore we had no heat all night. Temp in the house was 50-degrees burr. Thank goodness my husband was able to clean the acid off and we could get the furnace running. I hope we didn't burn up the furnace motor. This is not the first time this has happen with leaking. I had to throw away many items because they couldn't be cleaned. Duracell used to be the best until about 2 years ago. I would not recommend.

Disgusted-Lousy Product

I have come to expect cheap batteries to leak, but When I use a Name Brand like Duracell, I expect it to last without leaking. I used Duracell in my wireless mouse which I use on a regular basis and was Very Unplesently surprised when I first began to experience Low Charge symptems, it had already leaked acid alover the inside of my poor little mouse which had to be put to sleep as a result. I will never buy Duracell again.

Leaky Mess

in the last year , these batteries have leaked and corroded in my submersible flashlight , and my indoor outdoor whether station ,and my clip on headlight (clips on the brim of my hat ).
these are gifts from last xmas, now ruined in less than one year.

just one year since last xmas

I purchased Duracell "C" cell batteries for a three cell Mag-Lite that I keep in my car for emergency use. This flash lite is rarely used. I don't remember when I put these batteries in, but this week on one of those very rare occasions when I needed it , it failed to provide the needed lite. It was nothing more than a dim glow. These three batteries were labeled as "C" MN1400 LR14 1.5 Volt MAR 2014 Not very good performance for premium batteries.

Failed

I have almost always used Duracell batteries and have never had any regrets about spending a little extra for them. In fact, the only regret I've ever had has been the few times I tried using cheaper batteries. But today I pulled two leaking AAs from my two year old son's toy. Fortunately they had not ruined the toy, but since they were installed less than a year ago (dated 2017) in a toy my son rarely plays with, I was shocked to see such a mess in the battery department, which prompted me to search for reviews from other Duracell users. I'm quite dismayed by all the recent negative reviews regarding leaking Duracells, and I'm questioning why the quality of these batteries has declined. I do not like Energizer or Rayovac batteries whatsoever so PLEASE, Duracell, fix the problems with your product or I will be forced to find a brand that does not leak, even if they don't last as long. Having to change batteries more frequently sure beats having to buy new products that have ruined by leakage!

Leaking batteries

Reading the Reviews i am quite disturbed. I buy Duracell Batteries almost exclusively and have never had a problem with them. I work in the Fire/Rescue business and use Duracell products in all of my battery powered firefighting equipment. My helmet light for example, which is exposed to extreme heat, has yet to have a problem, or need a battery replacement. I have been using it for over a year. Extremely Satisfied!

Excellent
