accent Posted September 20, 2012 Report Share Posted September 20, 2012 My battery is dead after 3 years and 20k miles now I'm trying to find out what caused it. I tested the drain with a multimeter. The current was 12amps for the first a few seconds then drops to 2amps. Is it normal? Quote Link to comment Share on other sites More sharing options...
e350 coupe Posted September 28, 2012 Report Share Posted September 28, 2012 No a 2 amp draw would kill the battery in a day or two you could try pulling one fuse at a time to locate where the draw is. I would first disconnect any accessories or converters/chargers to see if you are still getting this draw. things like phone chargers, 12v/120 volt converts, after market radio's or dc power plugs and fan relays are usually the culprits.
