Hi, my apologies for the sort of double post. I have a 300D from 1977. The battery is dead - I came to this conclusion by noticing that the lights became increasingly dim and I couldn't start the car at all. Of course, I tried to play a cassette tape and the music slowed down progressively. So I am trying to charge the battery full again, a battery which was first used in April 2000 and says it has 72 months of life from that time.. oddly enough, the battery charger shows it as full - I know the charger works because I successfully used it to charge a minivan a little while ago. What might be going on here? I think the reason my car's battery went dead is because I haven't driven it in quite awhile over the winter months.
Thanks a lot and thanks to Alex Hemmerich for helping me get the hood open ;)
