Any idea what could be causing this?

I had this exact same problem today while assembling a small electrical board controlled by an EduRC. The problem turned out to be the 12V battery - it's voltage was around 9V and it wouldn't take a charge. Probably something messed up internally, a cracked cell, perhaps.
