Biggest Battery in 25 F150

[25fordlariat]

I've had my 25 F150 coyote for about a month and reading everything I can about these trucks. QUESTION What is largest battery I can put in my battery tray if my battery goes bad? Thanks in advance.

Get a H8 and don't look back. No more sleep mode, infotainment is fast, etc.

H8 for all but Powerboost
H7 for Powerboost

Your H6 binkie will not fit. You will need to buy a new one. They are not expensive. Available from Ford at various online parts places.

The battery change to H8/Group 49 takes 100% of its allotted room in the engine compartment. This battery is spec'd for certain trim lines. All cables hook up per factory specs.

Per Aonarch, don't look back.

H8 AGM solved my LSOC issues. Bought the battery blanket from Ford too.

I was looking at batteries the other day. I could not find any at the home improvement store where I was labeled "H8."
I guess I am a specifications person.
Is H8 the physical size of the battery and the "Group 49" the electrical capacity rating of it?

Those are interchangeable numbers. H8 and Group 49 are the same size battery.
