I got asked by a friend recently if I knew of a way to try to resurrect a dead battery. I knew I had seen something before about this, so after a quick search in Evernote, I found a link to this article from Darren Kitchen from Hak5. I am not sure if this helped my friend or not, I am still waiting to hear from him. But I thought I would post it up here, incase it helps anyone else out.
