I've got this issue, actually came one here to see if I couldn't find any info on it. My problem is the battery just goes and goes and goes without depressing the battery at all. I'm beginning to think it is my brand new attys that are causing it. I've only had 1 evo battery die (unable to charge) before this and in the matter of 2 days, have 1 dead battery and 1 that wont shut off due to this. The first one just crapped out completely, just burned itself out even with atty out. Kinda scared me, thought it would explode. The second one started doing the same thing, so I removed the atty as soon as I could. Light doesn't come on at all, but when I plug in the atty, it automatically powers the atty and will continue to do so until I unscrew it again. This is totally bogus. These have worked for soooo long but now they are dying left and right.
These happen to be TotallyWicked branded Tornado batteries using their 510 attys. What should I do? If getting a bad atty can actually kill my battery I'm thinking I might need a different device.
