badbenzz · 01-02-2012, 04:26 AM

Where's the battery....purchased car last Thursday went out of the country for 8 days and the car did not start. Called MB to start the car and the technician could not even tell me where the battery is located. How do you guys tickle charge your car, I used the one for my Porsche and it does not work since the cig. lighter goes dead when the call is shut off.
Thanks

It is underneath where the rear seats would normally be.

You're correct, the cigarette lighter type trickle charger will not work. I bought an MB trickle charger that connects directly to the existing battery port-like connector located in the upper left rear drivers side trunk, behind the removable cover panel. It's easily installed and all I have to do is unplug the AC cord. The charger stays attached to the battery port and remains in the trunk. It couldn't be easier and my battery is always charged. Check with MB parts, if I recall it was about $100.00 and well worth it!

Thanks hooked up the tender today. Battery is located under the rear panel in the center.

No need to access the interior battery compartment to use a battery tender.
There is a charge/jump point in the left side of the engine compartment near the shock towers.
Just flip up the red lid and you will see a connection point that accepts an alligator clip for the positive side of the battery.
Secure the negative to a common ground point not far from the covered positive point.
I use a $19.00 Schumacher SEM-1562A 1.5 Amp Speed Charge Maintainer connected to this point in the winter months.
As "LovemyBS" previously posted there is also a charging point in the trunk that accepts the OEM MB charger.

Thanks RBYCC the tender is currently installd with a pig tail hanging off the rear compartment for easy access. However, dragging the wires thru the window every time is not the most effective way to do it. Do you just shut the trunk on the wire when you use the MB version?

LOVEMYBS · 01-04-2012, 08:37 PM

Yes, I shut the trunk on the AC cord, no problem. When I'm ready to go I unplug the AC cord and store it in the trunk. I like simple solutions!

The only "not simple" part of the MB trunk-insertion point charger is that fitting the male end of the charger into the female end of the trunk port is a finger breaker. And, just as hard to undo. So, once you plug the male end into the female end, best thing is to just leave the entire unit in the trunk, including the power cord. I leave it that way for winter, but really cannot for track days. AS

I don't use the MB charger and trunk charging point.
I just leave my hood open and connect to the charging point in the engine bay.

Is it that hard to take on and off? lol. Was thinking about ordering one of the MB ones cause it sounds easy.

I don't recall it being difficult but that was over two years ago. Now that's its installed it just stays in the trunk until needed.
