I put new batteries in a Mini-Mag LED PRO AA flashlight 2 months ago and went to use it yesterday, and it didn't work. First things first - check the batteries. The end cap won't unscrew from the flashlight body. 
After finally forcing it to break loose, sure enough one of the batteries had leaked and eaten away the internals of the aluminum end cap and main body of the flashlight. "Freshness date" on the batteries - March 2026.
Duracell customer service was a complete waste of time of course. So it looks like it's on me to eat the cost of a new flashlight myself. (Surprise, surprise.) I cleaned it up best I could but the 'ring' that holds the contact spring in place is half gone. And the corrosion inside the tube has eaten 2/3 of the way through it. With the anodizing gone it won't be long before oxidation of the bare aluminum finishes the job. Never buying another Duracell battery again.
