Happened to me after I had my
Happened to me after I had my offlease 2013 for a week. The bat was so dead it dropped below 7volts a second after taking off the charger. I thought I had a lemon, with a short, but it was only a bum 12Volt battery. The dealer (I had bought it from someone else), kept if for a day to verify things were OK, and wrote it all off as warranty.
