My beloved MB '85 300D has been sitting for many (many) months and I need to charge her battery. Here's the scoop.... all I have is a 6 amp charger (6 amp med charge, 2 amp slow charge). I read through some threads and it seems that this might be useless. I have all the time in the world to have her hooked up, is this even worth trying? I'm too broke to buy something stronger, though maybe I can find someone to borrow a better one from.

There's more to this story, if you're curious. The reason that it won't start is because we had a sudden drop in temperature (I had commercial Biodiesel in the tank) and I could not get it going and seem to have either spent the battery or it's a glow plug or starter issue. There's just a "click" when I try to start. Before that it did turn over, but progressively lost steam.

First things first, though.... I'd like to charge the battery and then figure out whether it's an electrical or fuel line issue, which I've seen covered in these forums already.

I'd be grateful for any advice!
