2010 Mercedes-Benz S550 Question: Battery seems to not hold charge, had car checked at Mercedes dealer,
Answer #1pushrod November 16, 2013, 01:36Master
No other maker of automobiles has this problem, not even the cheaper ones! Ask the "Mercedes Benz" dealer to explain that to you! Sounds like a bunch BS to me. You most likely have a battery problem, is it the original battery? If so it's bout 4 years old now and may need replacing. Possible 'excessive' parasitic load on the battery also. Did the dealer check these things along with the charging system? Oh, i know about the many gadgets it has that may drain a battery, but not that quick. Dont let them get by with that explanation! Tell them to fix your car.

I agree with pushrod,that's a load of you know what! sounds like someone does not want to take the time to do a battery draw test. Usually a time consuming deal but must be done with concerns like this,and for customer satisfaction! something is draining the battery and with all of the electronics and switches in the vehicle it can sometimes take days to find an intermittent fault,but if your battery is dying all the time and it tests good...needs a battery draw test, which under warranty doesn't pay squat. 1+1=2
