I have a 1990 190e. It sat in my garage for about six months. Tried to start it and the battery was dead. Jumped the battery and ran the car for about an hour and drove it around the block a few times. Shut it off and let it sit for about 30 min. Started up just fine. Repeated about 4 times. Still no problem. When I tried to start it the next morning (about 9 hours later) and the battery was almost dead again and wouldn't start. You guys think it's a dead battery? Alternator? Thank guys!
