Lesiure Batteries Burford Duo

We can see the batteries under the passenger seat - but cant work out how to get to them - other than taking out the seat?

Not conversant with Merc seats but it's common to have to remove seats on Peugeot based vans, unless you can slide seat far enough forward to gain access.

My 2010 MB sliding seat is no good, swivel plate still blocks access. Undo 4 torx head bolts and seat and swivel can slid forward and rest against dashboard. Access then for battery.

As above you have to move the seat out of the way, not as daunting as it sounds!
