Under the front hood, passenger side.
The owners manual index has a listing for "Battery (vehicle)." On page 169, under the jump starting procedure, the manual illustrates where the battery is located and mentions "Open the service cover"Where is the battery located in my 2016 smart? Cannot find any reference to it in my Owner's Manual !!!!!
On my 2012 it is below the floor mat on the passenger side
I am looking for some information on changing the Battery, it looks like need to remove lots of parts. I know its located under the hood.
I have changed a couple, nothing complicated . You do have to remove the fresh air intake cover that hangs out partially blocking the area where you lift it out. No big deal, has 3 or 4 pushpins holding it on, remove that, the battery connections, and hold down, and then it lifts right out.
I know that Walmart and Sam's both carry the type 47 that our 453's.
