Silly question, where is the car battery located?


Thanks

I haven't looked but probably under right rear seat.

I think it is in the trunk as there is a small battery vent hose that sticks down back there.

It's in the trunk, the lining is fairly easy to remove if you want to access it.

Jeez are you sure thats not the trunk of the space shuttle? What the heck is all that stuff lol.
Thanks for the info.

Whoa, what's that bottle in the plastic bag? Is it some kind of tire sealant? I guess no more spare tire, huh?

Thanks.


Where/how would I connect a Battery Tender to it?

Read your manual, page 273.

Correction, Under the hood, passanger side , there is a red + and a post for the - side of the tender

On the 2016 C63 S it is not on drivers side but on the passenger side under the hood. (USA)

If i were to have the car jumped where would i would need to jump it from? The trunk??? I see on the passenger side hood there is a positive but i couldn’t find the negative.

The chassis is the ground. Any unpainted bolt or fixture connected (metal to metal) to the body (chassis) will serve as a ground.

On most any car that has a battery in the trunk, you are intended to primarily used the positive and negative connections under the hood. That includes any jumping, battery tending, etc. You would only need to open the trunk to actually replaced the battery itself.

In conclusion, RTFM.

This is all pretty well explained in the owner's manual. Time to read it.

Hey guys I’m shipping my 17 c63s coupe overseas and I was told by the shipping company that the battery must be disconnected while in the container. Where do I disconnect? At the front? Or back in the trunk? Is this gonna raise any errors or problems? Battery is going to be disconnected for atleast 3-4 weeks.. also once the battery is disconnected I shouldn’t close the trunk correct? Reason I ask is because I’ll be sending valuables in the trunk and didn’t wanna leave it open. Thanks 🙏

Just pop the hood and unhook the negative terminal from the battery and zip tie it away from the post for extra safety. I wouldn't even consider doing anything in the trunk since it's a pain. Won't hurt anything except your battery won't go dead from sitting.

brianc63s

thanks for the reply bud 🙏 I think that’s a much better option! Are you able to show me a picture of where the negative is that you’re referring to?
And thanks for the clarification, my service advisor at the dealer said that “I should take a booster pack because the battery might be dead”, 🤦🏻‍♂️ how is this possible if the battery is disconnected. Lol

4npower

The negative I speak of would be the black terminal/wire directly attached to your battery. 10mm to loosen the nut then slide it off and out of the way.
The battery won't drain in 2-3 weeks if there is nothing drawing current from it. I assume he thinks you are leaving it connected, which in that case you would probably need to jump it after a few weeks if that.

so are we talking in the engine bay, or trunk?

Well, the other MBs have it in the front but I thought the 63s have the battery in the trunk?

brianc63s

yea I think your right, his engine bay definitely looks different from mine. What year is your car?

According to the signature, forum member 4npower has two vehicles in the garage. 2019 GLC 63 S and a 2020 C 43 coupe. The engine bay shown is from a C 43 so it might be from the 2020 C 43 coupe.
