That's what i think too. My three stage charger is specifically designed for preventing this, but it was not plugged in.

This deep cycle was manufactured for use in a variety of auto applications, such as police vehicles. It has good cold cranking ability, but I need my charger to prevent sulfation of the plates.

This is not much draw but If the vehicle sits for a few weeks without starting the battery will die.
I wish I had kept it plugged in!

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
