How to replace engine battery on 2012 E450.

It's time for a new engine battery in my 2012 E450. I've changed batteries many times in my autos but never changed a battery in a motorhome. Do I just remove the old one and install a new one or is there a something I'm missing?

Nope, nothing different.   Remove cables... Negative first then positive, unscrew hold-down, lift old battery out.  Put new battery in, screw in hold-down, attach positive cable then negative cable.... You are done.

I would also clean the inside of the connectors well with baking soda and apply a very thin coat of petroleum jelly to them and the battery posts to prevent future corrosion.

I usually take the opportunity to clean out dirt, leaves, pine needles, bugs, etc while I have the battery out.

Thanks everybody!
