How does it work with my mercedes with the battery in the trunk?

If you get the cigarette adapter, you plug the battery tender into the cigarette adapter and then into a wall outlet. You never touch the battery at all! It charges it through the cigarette adapter.

I would think you would attach the pigtail with the alligator clips to your battery terminals and attach the pigtail to the charging unit

Car type does not matter. Install the supplied "screw in" connector at the battery rather then the clips (you will need to get to the battery under the trunk liner). This connector will stay at your battery, then just route the connector in the trunk for easy access. Then connect the single cable to that connector anytime you want to charge. This eliminates the clip mounting each time to the battery and becomes a one cable connection. This is all included with the kit--great stuff!

I do not know te Mercedes layout but in my BMW, I open the access to the battery, make my connections to the exposed terminals, plug the unit into house power and close the trunk with the unit inside. I leave it connected each time we are gone for over 2 weeks.

It works with any 12 volt lead acid automotive type battery. If your battery is of that type then it would work. The tender is to be used mainly for storing batteries for long periods of time. It will keep the battery fully charged so it can be put back in use when you are ready.

It will draw power from the car battery but the alternator will recharge it fine. Only issue would be if you recharged it a few times without running you car. Then you might have to get your car jumped!

I have one it is a backup battery that is hidden. So if the main battery would get cut or disabled the car is still protected. Its just an extra layer of security.

none. you have to connect the supplied plug to the 12 volts battery of your car.

You can either hook it up directly to the battery or you can wite it through a fuse in the fuse box of your automobile.

No, The battery back-up takes the place of your battery ,if it goes dead or someone tries to disconnect it. Your security car system will still have the power it needs to protect your car.

I'm not sure what you mean. If you're asking if it will still work without the car being either on or on accessory, every car I've ever been in does maintain power to the cigarette outlet even when the car is completely off. If that doesn't work, just turn your car on accessory and it will work fine. You just turn the switch on the invertor on. I'd recommend turning the interior lights off in your car while doing this or run the cord through the window to prevent running the battery dead. If you do that, you won't have a problem with your battery going dead, not even close.

It connected to my Mazda6 steering wheel controls. I can't speak for the mercedes, but I can for the mazda6. It works great - I've had it for over a year and the stereo is wonderful. I highly recommend it.

On the plug and play installation, its just plug and play. Some vehicles may require a relay which gets connected to the Battery.

Not that I was aware off. I wired mine to the inside from the outside battery. Just have to make sure your wire gauge will handle the currant. All you are doing is cutting power. No different than wiring you car battery to the trunk.

I connected to the radio power wire. That way it works for a few minutes even after the key is turned off. Every vehicle is different of course. If you do go to the battery direct, be sure to put fuse coupler in next to battery. I have had mine installed for over a year and so far works great.

I have never had to start the car. It works just fine just from the battery.

I haven't had any battery problems with it. It doesn't take much energy not like a cell phone would. I unplug mine sometimes because it gets nice and strong. It deodorizes the entire vehicle not just the front seat. I just gave my last one away and need to order a half dozen more for our other vehicles.

I use it in my mustang and Nissan Sentra and haven't needed to strap it in. It doesn't really move once you set it in the trunk.
