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 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.
