i'm trying to get to my 2017 ford fusion's battery because i think it may be dying, but i can't find it. the pictures and videos i've seen online show an almost entirely different interior where the battery is plainly visible and needs to be pulled out of somewhere, but i don't see anything like that here. is it the silver metal box? i see an electricity warning on it but nothing else. i think it would be weird if it was inside of this box thing but i don't even know what the box is and i'm worried about starting to disassemble pieces before i know what they are.

any help appreciated
