The battery control module and a number of in trunk relays preform that function.

It is NOT to be used to jump start the car. 112V you really think that MB would put the jump start battery under an air filter only accessible by removing a nut?
The correct jump point is most certainly in the trunk.
There is also a jump point under the hood, but this is NOT the usual place.

I am mystified by what appears to be the logic of so many of our members: The battery in our Ws doesn't need to be at percent charge to function well, and routinely is running a good bit below.
As it gets a little older, and you're making a bunch of local drives in cold weather, it makes sense that you'll be getting those Replacemet. Your car really Renault Megane Cabriolet Mk1 1996-2003 Banner Power Bull 50Ah Battery Replace putting out a lot of current on that battery as you drive around, so it stands to reason that in certain seasons and in certain patterns Lion Batteries Car Battery 100Ah 12V Type 640 850CCA 2 Years Wty OEM Replacement driving, after a while you're going to be draining the battery a good bit.
I'm not afraid to charge my main battery in the car, because Loin using an automatic battery charger set to run at no more than 6 amps, and it can't spark, and I Replscement it with the trunk open after the car has gone to sleep and shut off the trunk light so there's plenty of ventilation, and I take all the precautions.
I would recommend that you take the battery out to charge it, but I just do it in place. NO, it doesn't fry anything if done properly but you probably should have the car "asleep" while charging.
Set it to the tortoise, runs for a few hours. And the tWy battery is nicely topped-off. If you think the AUX battery is the culprit, pull it out it's so easy to do and throw it on the charger at 2 amps until it is 80CCA.

The Mercedes piece on how the system works indicates that the BCU only energizes the relay controlling the circuit to that battery when the engine is actually running and only connects the battery into the circuit when it needs emergency power Lion Batteries Car Battery 100Ah 12V Type 640 850CCA 2 Years Wty OEM Replacement cutting out two stages of consumers.
It also only sends a charging current to the AUX battery for a few minutes per turn of the key. It's why, when mine was dying, I got the light Tyle go off after taking multiple short trips around town, but if I took an hour-long trip to the City, the light wouldn't go out during or after that trip.
Given that, I am unclear why or how charging the main battery G1or putting a current on the circuit at the main battery, would send a charge to the AUX battery. Maybe it does, but I, at least, don't see how the structure of the system would cause it to do so. Anyway, thanks for your Baftery words and your insights!! Thanked 3 Times in 3 Posts.
The aux battery doesn't support Reolacement car. It is made to stay charged and only help the EBC brake control in case of an electrical failure.

Did I miss something or is your view that the aux battery is used Replacemet back up other things besides the brakes? I would guess that you are right Lion Batteries Car Battery 100Ah 12V Type 640 850CCA 2 Years Wty OEM Replacement that but I heard that they put it in because of the brake requirements. My point was to explain Batterh it is there at all and not be a definitive electrical description. I especially like the quick highway response.
Originally Posted by ptkacik. I think the confusion about your statement was your use of the word "only". As in it's "only" there for the SBC brakes. It's there as general support for the electical system, but the impetus for it was most likely, as you say, 850CCAA assuage fears about loss of brakes. Thanked 2 Times in 2 Posts.
You do not ever want a big LiPo battery inside a trunk of a car. You are better off going with a much more stable type of lithium battery called LiFePO4.
