There was a time, when Duracell batteries were only made in the U.S.A. The issue here isn't the type of light, or how long the bstteries are in it, or even whether it's used or not! It's simply down to the quality of the batteries! It gets used on average once a month or so. It still has the same two steel-clad Duracells I put in the calculator sometime around 1980-82. I have an ancient Canon pocket calculator i used in middle and high school, it now resides in my basement workshop toolbox. Rather than risking damage, I replaced all the cells with a different brand.

I checked all the detectors, and found another cell leaking. I tossed out over a dozen fairly new Duracell Quantum AA cells that I had put into the smoke detectors not long ago, one began chirping the low battery warning in about 5 months, when I checked, one of the three cells had begun leaking badly. There simply isn't any sure way to predict if a battery will leak, in most of my cases, the battery is still putting out decent voltage when it began to leak, these aren't batteries that have long died and were forgotten. Then there are some items that don't like the slightly lower voltage of the NiMH cells, so those tend to get regular alkalines.

For things like radios, electronics and other stuff that gets regular use, I use Eneloop or similar low self-discharge NiMH cells which are far less prone to sudden leakage, but aren't immune. For AA, AAA and 9 volt applications, I will use lithium primary cells (Energizer Advanced or Ultimate brand) for items that get intermittent use yet still need to be ready for immediate use. No matter the major brand, I've had them all leak to varying degrees, damaging or outright destroying things from flashlights, remotes, test equipment, you name it. Overall, I got to hand it to Duracell for how they handle this sort of situation.
#DURACELL BATTERIES LEAKING CODE#
Maybe due to being in Canada, or the date code on my battery was enough to confirm it was part of a known bad batch. They did not request return of the flashlight. the rest was filled in with friendly banter about where the call center was located, batteries in general, weather, and other small talk. They asked the typical what happened, how I store and use my flashlight and asked for the date code on the battery and the location it was printed (I was able to extract one battery). Bonus was, I could understand every word she said and didn't need to say 'what?' every third word to hear it, or figure out what she was actually saying. And the lady I was talking to was in Wisconsin. Two thumbs up to duracell for a no hassle experience.
#DURACELL BATTERIES LEAKING FREE#
I called up the Duracell customer service number and they provided me with a coupon for a free pack of batteries (max 24 count), and they sent me a cheque to cover the cost of the flashlight. Batteries where Duracells (my preferred battery, still is). It killed a Rayovac Indestructable AA flashlight. Guess luck has been on my side all this time. I experienced my first battery leakdown in a flashlight this past february.
