So, I'm a little confused and find the salesman at dealerships to be average on answers. Since some of you guys actually OWN hybrids, I figure you're the best resource. It's all about the battery in a hybrid. First, can the battery die? If so, can you jumpstart it? And, if it's just a rechargeable, can't you simply leave the lights on (or some other sort of power-draining activity) and then when the battery gets low simply let it coast down a hill while applying the brakes to re-charge? Just curious. Oh, and if those are all true, can't I hook up my TV and satellite to the car's power supply for game day tailgating, and then recharge as necessary? Does it work this way?
