Where is the main battery located in the trunk?

Thank you, but that is not where it is on the 2008 2 door cls550. I took out the entire lining There must be some panel that you. Can't See by just removing the floor panel in the trunk. Where yo from there?

did you remove 2 panels?remove floor panel first,then another panel covers the spare tire.battery should be there. if you are replacing this battery,do not unhook battery,before hooking up a memory saver,so it will keep 12 volts on your cars computers,also keeping all the memory and presets.if it is not under the spare tire cover,look on pass.side trunk for panel.they are in different places on some years and models.be sure to put an AGM TYPE BATTERY BACK,IF REPLACING.do you have owners manual?this is for the 2008 s550,should be same as cls550. copy and paste link.see picture.
