I heard that a AGM battery is not recommend for 2017 Ford F350 because the alternator will charge them wrong and it short the life of the battery.Anybody know that?

Possibly. Not just Ford's.

AGM batteries can be charged at 40% of lost amps vs lead at 25%,gel at20%.
So if you have too small if a power source, the battery will not charge correctly. Or you will blow up power source, ie alternator because you are working it too hard
This is a big issue in boats, with house battery makeups many times bigger than land yachts.

I ran an AGM in my 02 V-10 Excursion for near 10 years, still was in there when I sold it. I also run one in my wife’s 13 Explorer with no issues. 2 years ago I put one in my 12 V-10 Class A. AGMs work fine, I’m fact a lot of the newer vehicles come with them from the factory.

The real question is why bother for a starting battery.

The main advantage of AMG is they don't spill if you roll them over. Great on a boat or a stunt plane...not so much for a starting battery.

I would say the biggest reason is that they are maintenance free. A lot of people these days don't even know how to open the hood.

There really is only one benefit for a AGM battery. No liquid. Not sure if that would be worth the extra cost in a typical under hood installation.

But regardless of all the "reasons" y'all appear to have for why you don't need an AGM battery, the fact is, they will work just fine in a 2017 F250, or any other vehicle.

An AGM is a much more stable battery, can be ran down a bit farther than FLA batteries. For these 2 reasons they are a better choice!

No no nooo! You got it all wrong, lol.
The old farts above (some of which are our resident camper battery geeks) say it’s a bad idea , not necessary, foolish etc.
Oh wait, they’ll say the opposite to basically anything….

NO. I don't buy that.

For superior cranking amps and slight advantage on voltage, additional freeze resistance, faster charging, zero maintenance AGM is a great choice at a premium price.
