This killed my Die Hard in my SD just recently... well the fully working HVAC system did. The puny alt was just not able to charge the car at idle/my city driving with the lights on, blower on max, HVAC relays on, clutch engaged, etc Bought a 150A, problem solved. I never encountered this issue on my other stuff as I have upgraded the alts in all of those already... did not dawn upon me to be proactive and swap it. Oh well. I was told the big issue with the small alts and these batteries is that they are almost all not Maintenance-Free which does not allow them to charge well.

UPDATE:
I am driving the BMW this week. I pulled the battery out of the 300SDL and have been charging it with a trickle charger for two days now. I charged it for 6 hours on Sunday. It went to 13.04 Volts and then on Monday it settled at 12.5 volts. I charged it Monday for 6 hours and it went to 13.1 volts and I could hear it " cooking". I unplugged and this morning it was still at 12.5 volts. I will let it sit all day then charge it again tonite. I know it would be a whole lot easier to just go buy a new battery, but I do not need the car this week and I want to play with the battery and charger. I am going to do this till Friday night and then re-install it on Saturday and see if it works. If it does not work, Saturday it is new battery day.
