Difficulty, time, and cost are estimates when this guide gives them. Torque is a cited figure, or it is left off.

Wire brush
If you see corrosion, the book says to remove the cables and clean them with a wire brush. It also names a baking-soda-and-water mix for acid.
Battery carrier
The warning says to lift a plastic-cased battery with a battery carrier or with your hands on opposite corners, not by squeezing the end walls.

Use the Motorcraft table for the engine, including the Intelligent Access and Auto-Start-Stop footnotes. Do not move the 2.7L number onto another engine.
Keep the top clean and dry and the cables tight. If the terminals are corroded, remove the cables, brush them, and neutralize acid with baking soda and water. Put the cover back on.
The book sends replacement to a dealer and a Ford battery that matches the electrical requirements. If the cables were disconnected, follow the printed relearn, including a drive of at least 12 miles.
The cluster message Key Battery Low Replace is the remote key, not the under-hood battery. This printing does not give a key-battery part number on the Motorcraft tables, so none is added.
Dispose of the old battery through a local recycling authority. The book says to ask that authority where to take it.
Outbound links only. BaySheet does not sell parts. Confirm fitment on the retailer page. Amazon links are searches for a real part name plus this vehicle. Tool rows do not get a product search. The search is not a part number.

Tool
Battery carrier

It depends on the engine. 2.0L is BXT-90T5-590. 2.7L is BXT-94RH7-730. The 1.5L and 2.5L tables list more than one number and footnote Intelligent Access or Auto-Start-Stop. The book says to have a dealer replace it.
The book calls it a Motorcraft maintenance-free battery that normally does not require additional water.
Idle and fuel trim, the clock, and radio presets can be lost. The battery chapter prints a relearn drive of at least 12 miles.
The maintenance checklist is on the site now. The email list is not sending yet, so this box will not store an address.
These guides cover the same kind of work. Their numbers belong to those vehicles, not to this one.
