I think I already found the answer at Dead/Dying Battery Diagnosis & Testing... but I'm hoping for an update.
I went out and tried to start my 2008 Redline. Dead as a doornail. I hooked up an 8 amp charger for 24 hours using the "proper" method and got nothing. Moved the positive connector directly to the battery positive terminal and still nothing. The charger showed "charging" continuously. When I connected both leads to the battery terminals the charger indicated no charging which implies there's one or more dead cells in it. I did hear some clicking while charging but couldn't track it down. And since the battery is dead, I cannot remove the key from the ignition nor shift the car into neutral. Gotta love those engineers.
So, aside from what the cited thread says, could there be another draw killing the battery?
