I parked car in the garage and left the dome light on....for 4 days. Now the fucker won't start. I put the 50A quick start on it and my battery charger basically said "nope" and switched to the 2A mode. (i have one of those Shumacher $150 smart chargers). So I put the fucker on 10A and checked on it an hour later, it said the battery was charged....NOPE. Car wouldn't start. I'm thinking about just jumping it and letting it run for awhile. The battery is about a year old, but I'm afraid if I shut the car off tonight it will be dead. A battery for the car is not cheap, $150 for a good brand or $239 for an Optima Blue Top. Should I just bite the bullet and get a new battery?? The idea of shutting it off, then having it not start and having to put it on a tow truck while I'm on duty doesn't sound so good either.
