HiCustomer Thank you for asking your question on JustAnswer.
The vehicle needs to be elevated on a hoist and a transmission jack is used to lower the tray and battery as an assembly,then the cover and cables are removed. Its a bear of a job if you don't have a hoist and a trans jack.

my ford dealer says they are on a tray also, i see no "tray", just two boxes attached to the outside of the passenger side frame rail
HiCustomerthis is lostrider, here is a diagram of the battery mounting, does yours look like this?
Thank you for the reply, the way the batteries are mounted to the frame, Ford calls this tray mounted, here is the procedure, according to the replacement procedure it will lower enough to remove the top cover and the terminals and yes they are top mount batteries, hope this helps.
Removal and Installation
CAUTION: Failure to accurately follow the battery disconnect procedures described in this section may result in vehicle or component damage.
NOTE: The preferred method of service requires the use of a floor hoist to lift the vehicle overhead, and a transmission jack to support and lower the frame-mounted battery case.
NOTE: The frame-mounted battery can be charged while the frame-mounted battery safety straps are connected to the vehicle. Follow the procedures up to and including disconnection of the frame-mounted battery cables.
Vehicles with 6.0L engine
CAUTION: Make sure the frame-mounted battery negative cable does not contact the frame. If necessary, wrap the terminal with electrical tape.
