Try disconnecting the alternator electrical connectors, if it still goes dead have the battery tested, it may have a shorted call.

SOURCE: MY WILL NOT START THE CAR C240 MERCEDES BATTERY IS NOT DEAD

I am assuming that the engine won't even turn over. could be lots of different things. The simplist is to make sure the car in in PARK , won't start if not. Other things could be , Security imobilizer if you have one. Does your key have a electronic chip in it ? Try your other set of keys if you have one. Check if battery connections are clean and tight.

You have what is called a "parasitic drain" that is draining the battery on your car while is not running. Something is staying on after you turn the key off, it could be any number of things, from a stuck relay to a trunk light staying on that slowly drains the battery. A parasitic drain test will need to performed to determine the cause so repairs can be made....Here is a link that explains how to do this test....Make sure your battery is fully charged before starting this test. Also, after you disconnect the battery cable, wait 15-20 minutes before starting the test...this allows any capacitors to drain and not give a false reading...
Good luck, i hope this helps.

Hi, The battery has suddenly drained on my 1999 T Reg Mercedes C Class Estate. Yesterday the horn suddenly sounded for no reason and would not stop....then it stopped on it's own. This morning, no power in...


According to the Mercedes forum, you are not alone, the alarm system goes off at random, it has something to do with the tow button, disabling the horn doesn't stop the alarm and the lights keep flashing. But the horn is quieted. I would trash the alarm system, or pay the dealer to mess with it, which is usually an expensive joke. You have insurance on the car, let them steal it. I stopped worrying about my bike, I leave the key in it. Nobody touches it. Before I couldn't leave site of it. Now, I don't care. Let them have it, I'll get a new one, Anyway, check out mercedes forum.

do a battery leak test, separate the neg cable and jump it with a test light, it should light and then dim, if not something is staying on, look for a light or radio that is staying on, i usually pull the fuses one at a time till the light goes off, but dont get fooled by the ecm fuse it always draws a little, then chaeck cables on the battery , and check alternator voltage charge, should be approx 14 volts, driving it every day is bunk, or there would be a lot of dead cars in the citywhere people use them only on the weekends, as for the spring i would have to see it

What is draining my battery on my c220


Maybe the alternator. You can take a test light, connect it to the disconnected positive cable and the battery positive terminal. Make sure everything in the car is turned off, and the doors are closed. If the test light lights, something is draining the battery. You can go to the fusebox and pull 1 fuse at a time, when the light goes out, the problem is in that circuit.

My alternator and battery tested good.


Something is draining the power. You have an open circuit somewhere. The sooner it drains(1-2 hours) the bigger the load, the more heat you should be able to detect from the drain. If it takes a lot longer(like overnight) then it will be a little harder to detect. Try unhooking things one at a time. Your alternator could be working properly when the car is running, then shorting when its off. That would make the drain fast. A light staying on under the hood or in the trunk, or dome light would make it drain slower. Or it could be just a wire shorting to ground.
