what can cause the battery to die when car is parked for 2-3 days?
So I have a 2002 mercedes c240 that if i leave the car parked for 2-3 days without
starting the car the battery goes low and i need a jump every time that happens, the
battery is brand new. I understand that there is something using the battery while the car
is parked, but what can it be. Thank you
First,i know the battery is new,but to rule it out,it need,s to be load tested,to see if it has a bad cell,even thoe it is new doe,s not mean it,s good,then if battery is good,you need to make sure there is no electronic,s or light,s on in the car,this may take a while to figure out,and you may need to take to a mechanic,to do a draw test on the car,when they do this they will see a draw of the battery,then they will have to go through each fuse and pull them one at a time to find the culprit.But my money is on a bad battery,,good luck with it.
I have seen alternator that was wearing out put a load on the battery while parked, with similar symptoms to those you describe.
You need to disconnect the seat module underneath the seats and check which one is faulty. That seem to work for me.
