Thank you so much for showing this , I have one like this for my mercedes c200 year 1999.
When I opened it I found 2 batteries inside and I thought it was wrong , so I searched and found your video which confirms to me that it does need 2 batteries so a big thank you to you

I don't think it's technically possible for 2 things to sit on top of each other. Sorry, I'm a little OCD that way, nice video :)
