95 e300d. The battery in the car now is a duralast purchased new in Jan., 2006. Yesterday, I left my primary headlights on for around 75 minutes. It wouldn't start. I've left my lights on before, not for that long, but an hour and 15 minutes doesn't seem long enough to prevent starting. Am I wrong? I checked voltage a couple of weeks ago and alternator is working and battery is strong.

So, sitting there in Charlottesville, 100 miles from home, I called MB roadside assistance. I got a call back after 5 minutes saying a tow truck was on the way. 1.5 hours later, a guy in a wrecker comes by, barely touches the jumper cables to the battery and it starts. Guy says MB Roadside covers the cost of the jump. I tipped him and drove home. Even though we waited a while, I was really surprised the jump was free. My insurance would have covered it anyway, but still it was cool.
