I have a Red Brick that had always worked great, until I left it on my (powered down) Epic overnight. I think that the little power LED on the right side of the camera drained the Brick all the way. When I push in the button on the side of the battery, the first red LCD flashes. And when I put it on the Red charger, the charger LED flashes orange, fast, for about thirty seconds and then flashes red, and slower, for about a minute. Then it repeats the entire cycle. Figuring I had nothing to lose, I put the Brick on another V-mount charger, and it sat in pre-charge mode for quite a while and then displayed a Time Out message. The battery doesn't get hot, or produce burning odors.
Does anybody know if draining a battery in this way (if that is what happened) permanently trashes it? From the searching I've done on RedUser, it doesn't look like there are a lot of great options for repair.
