Hi all, I drove to work on friday, car started fine got to work no problem. Left work after about 30mins and the battery was dead. Had it jump started with a battery pack, went to get groceries and car started fine. Went back to work the same night, started car, drove to work, no issues. Finished work after 5hrs and it's dead again. Tried to jump it and it was a no go (wouldn't crank over at all), checked the battery's indicator and it said 'take to dealer' so I assume it was toast. Borrowed a brand new battery and car started and drove fine for a day and a half. Was going to head to work last night and car was dead again. I haven't done any electrical work on the car in about a year so AFAIK there's nothing draining the battery. So only thing left I can think of is a faulty alternator and the car has been running straight from the battery without charging which is probably what killed the previous one.
