    i got this prius for free from my sister 2 years ago.

    i did a few infrequent 100-300mile trips the next 6 months.
    then it sat idle for most of another 6months.
    the next following six months i took it on a long road trip and half way through the trip the battery completely failed on me and i replaced it, and then i would let it sit for weeks at a time and each start up, it would need a jump.
    i didnt drive it the past six months and now the 11-13 month old battery is at 1.5v :cry:

    the only troubles i know this car has is a bad infotainment screen ...can that cause problems that utterly kill the expensive AGM battery?!?!

    ugghhhh, i just wanna sell this car but i imagine that will be difficult with a dead flat battery.

    Oh it'll be very difficult because it's an old Prius owned by somebody that doesn't know much about owning a Prius and so on . So disconnecting the battery was never even thought of ever? That's quite interesting I would think trying to sell the car wouldn't even come on your radar . Maybe donate to PBS . That sort a thing . because certainly selling vehicles powersports equipment and the like sounds like twill be problematic for ya.

    just buy a battery and sell it, it's worth a fortune!
