Access house batteries in Ford SMB-RB50

[Ruthless]

We still have the original house batteries in our 2012 Ford E350 SMB. They are losing their charge rather quickly so I figure it's time to replace them. My question is: How do you access them? The batteries are under the bench that pulls out to make the bed. Is there an easy way to remove the seat? I'm not finding an easy way to get to them.

Greetings Ruthless -- look for some wing nuts at each end of the bed - unscrew, etc. Take out bed - hopefully access ? OR - you have under chassis house battery - if so you need to take it to a garage and have it dropped out via floor jack, etc. Very heavy at about 130 lbs if its a D4 battery ? They run about $450 plus - unless yours is lithium - then cost maybe $600 plus depending on brand --

Good luck
