Hey everyone i would like to say that i really enjoy reading all the post and replies. I will not take much time from everyone, i just had a quick question. During cold days (30's and 40's) when my car stays outside (not in the garage) the batterie goes dead. I have to jump start it every time, and once i do that the car works fine. is there i am missing out on, or something i am duing wrong. Thanks for everyones time, i am up for any ideas.

C320 2001, sport pack 60K

Thank you everyone

 

how old is your battery?

bad batteries got reduced cranking power when cold.

 

sounds like dying battery. after you jump star the car, you need to keep it running for a while.
if you haven't changed the battery yet, maybe it's time to get a new one.

 

Running on OEM Mercedes battery? Definitely time to get a new one. MB batteries are notoriously bad. Get DieHard International from Sears. Only $80. Sears might tell you that their battery is 20 cranking amp shy than the OEM Batt. But no worries, DieHard is much better. Have radio code ready. Remove negative terminal first, and put it back last. Or **** hits the fan.

 

Now you're a Rookie with one less problem. Happy motoring!

 

hey everyone sorry it took so long to get back, i was in vegas for 2 weeks, yeah i will try to see if it is a bad battery, if now what else could it be, thanks everyone for the time.
