Mercedes 320 SC, 2013. New battery dead in a week
Hi, my old battery drained out rapidly,
within a week or two sometimes if the
car wasn't driven, so I had a new one
installed and it too was dead within a
week. Had it recharged and same
issue again. It's infuriating. Help?
Before first battery went I noticed the
indicator lights were all flashing when
it was parked and locked but not
caused by a break in. Anyone else
had this problem, or got any advice for
Parasitic drain. Watch this video. Eric knows his stuff - https://www.youtube.com/watch?v=KF1gijj03_0

This is all under the assumption your alternator and battery cables are good, have a good ground- http://www.aa1car.com/library/battery_runs_down.htm
Fordnut is spot on with the alternator and battery cables. Those are common culprits.
