Battery drain MBenz E500 2003

Asked by penny Aug 21, 2019 at 04:12 PM about the 2003 Mercedes-Benz E-Class E 500

Question type: Maintenance & Repair

Hi I have a w211 MBenz e500  2003 and I
have something draining my battery. Aux.
Battery is good , trunk is locked so can't
check main battery but believe it's good . Not
very old and tried removing electric seat
modules and nothing changed. When I start
it and drive a good 80 miles or so it's start up
every time for like 4 days. I found something
very strange and this is my question. Would
any one know what reason the cigarette
lighterr ports front and back when I put a
USB adapter in them to charge my Android
phone took my phone from 19% battery
charge to 2%0in a matter of ten minutes. It
was flashing on the phone as though it was
charging and instead ended up running the
battery down to almost nothing . Is this an
indicator of anything common . Please let
me know . Thank you

I actually think that is in good working condition but that info. Came from a friend that is great with cars but wasn't a professional diagnosis.. We've been trying like process of elimination to get to this issue. I will get that trunk open , too,!! Lol
