Well it finally happened. I went to use my Acebeam M10 today and when I picked it up I noticed the tell tale white powdery build up near the pocket clip. I knew there was a Dura-leak in there, but I had put a fresh one in approximately 1 month ago during a power outage. One of the maintenance personnel from our building was my office when the lights went out. He commented on how his flashlight was downstairs in his work area. He is a nice guy so I let him borrow mine. Normally I keep a 14500 in the light but took it out and put in the AA alkaline because the light can get quite hot running on high with the 14500. Anyways I get to go home for the day and find the light on my desk the following morning. I return the light to my backpack forgetting to put the 14500 back into the light. Fast forward to today and the lights start flickering so I decide I want the light in my pocket rather than my backpack. Ok I admit I was planning a trip to the bathroom when the lights started to flicker. As we all know if I had not taken a light the power would have cut out completely.
What really surprised me was the leaking cell had eaten right through the battery tube of the light and in so little time. In one month after the install? The cell itself still measured in at 1.52 volts. I cant make out the expiry date on that particular cell due to the corrosion but the rest of the cells I believe are from the same package show a date of Dec 2029.
Now I think back to all that light has survived. It got sucked in to a snowblower and left outside until I found it 3 months later. I zip tied it to a caving helmet where it was bashed around and still worked but one cheap battery killed it. I was able to get the cell out and to its credit the light itself will still function but it has a 5mm x 2 mm hole in the side now.
Anyways I will upload the pictures for your viewing pleasure or displeasure.
