I may get some flack from Duracell fan boys, but frankly I can't understand why they'd be in the first place. I'm writing this to convey my dreadful experience with Duracell batteries over the last 10 years. So back about 10 years ago, I'd run into a problem with a flashlight that stopped working, an AA sized Maglite. When I went to open it, the batteries wouldn't come out. Why? Well... they'd leaked and corroded the inner wall of the flashlight. I tried all kinds of techniques to coax the old cells out, but they wouldn't budge. In my frustration, I used a sledge hammer to crush the damned thing. And when I looked at the debris, I saw "DURACELL". OK. Batteries can leak on occasion. I'll let it pass. In the years to follow, I'd find a remote control here, a radio there, and a few other flashlights that would suffer some damage from battery leakage. Time after time it was one brand guilty of the crime: DURACELL. Just a couple of years ago, after having a rash of battery leaks in a couple of devices at once, I decided to take photos and contact Duracell about this problem. After a week or so, I finally got a response. "We're sorry for your trouble. We've never ever had a complaint like this. We'll mail you a few coupons for your trouble." No complaints? That prompted me to search the Internet. Sure enough I found Amazon. Guess what? LEAKAGE REPORTS! Plenty of other people complaining about the same problem. Well, I thought maybe DURACELL might have just had a bad decade, but I'd thought that I'd make the effort to remove all of their batteries from my devices and swore never to buy the brand again. BUT... DURACELL got its last laugh on me. Sure enough, I didn't realize I'd used a DURACELL battery in a small electronic prop for Halloween the year before last. I opened it up and... leakage! The date on the battery? 2016! Screw Duracell and their substandard batteries. I will never ever buy them ever again. And I strongly recommend everyone here do the same. Do not torture your flashlights with the risk of death by battery leakage. Stay away from DURACELL. They ought to rename themselves LEAKACELL. FOOTNOTE: While encountering this rash of DURACELL battery leakages, I was also employing Energizer batteries in various devices as well, sometimes intermixed with a DURACELL battery. I only had ONE Energizer have a problem where I saw a bulge indicative of an impending leak. So, it wasn't just a blanket claim of "all alkaline cells will leak"... it was a certain brand exhibiting it far more often than a competitor brand. Note that I also use NiMH, Lithium Ion and LiPo batteries in most of my flashlights, at least the ones that support them. It's not advisable to use them in flashlights that will be potentially exposed to great heat, like ones you tuck away in the trunk of your car.
