Gotta replace two group 65 batteries on the F350. 750 CCA minimum.

Do I pay an extra $55 per battery? Truck came standard with motor craft wet batteries.

I figure if it didn't come with an AGM, it doesn't need one.

The WalMart ones are 4 year full replacement. Mine usually last just under 4 years and I get two new ones for free for my F350.

The regular WalMart batteries are only 3 year full replacement and they last just over 3 years in the vehicles I've had them in.

If they had the same warranty, I wouldn't get AGM batteries for my F350. Florida heat kills them just the same. AGMs take a pounding better and will last longer in boats or high speed off road vehicles.

I would stay with what you have and reset the Battery Management System (BMS). It's set up for wet cell.

AI:
You do not need dealership programming or a special scan tool to replace an F-250 battery. However, you must reset the Battery Management System (BMS) so the truck knows it has a fresh battery and adjusts its charging rate.

You can manually reset the BMS on Ford trucks using this simple, proven sequence:Turn the ignition on (engine off).Flash your high beams exactly 5 times.Press and release the brake pedal exactly 3 times.Wait about 10 seconds. The battery icon on your dashboard should flash a few times to confirm the reset is complete.

If the BMS is not reset, the truck's computer will assume the new battery is old and degraded, which can undercharge it and shorten its lifespan.Important: If your F-250 has dual batteries, replace both at the same time to prevent unbalanced power and premature battery failure.

I think they are worth the upgrade but thats me

Standard car batteries can’t keep up with the backup cameras, Bluetooth connections, touch screens and other electronics. That’s why you might need to jump a car if you leave your headlights on for a couple hours with the engine off.

Draining a car battery to 50% or so before recharging it is called deep cycling, and only AGM batteries can. They’re designed to deliver amps and then give a big burst of power to start the engine. And they can do it dozens of times a day.

Depends.

I bought an AGM battery and have had no problems since.

That was in 2012.

I bought one for a small tractor (28hp) that I use 3-4 times a month. That was 7 years ago, no problems.

If the battery install is a pain in the ass or would be a major inconvenience, then AGM for the win

His truck's TWO group 65 batteries keep up with everything well.

I went with the standard wet batteries from Costco.

$124 each, Walmart had 650 CCA and I did experience tough starts during really cold weather this past winter with the factory 750CCA batteries. The Costco batteries were 850 CCA so hopefully that keeps me from getting stuck in the snow.

What’s crazy is that ford and parts stores want 330$ each for the motorcraft factory batteries. Ain’t no way they are that much better.

Yeah, it’s only an XLT model so not too many gadgets. Only Auxiliary stuff is the one board compressor, which uses an analog gauge so not much to draw there.

Also the 7.3 gas engine so not as much required for cold starts either.

My getting old memory isn't what it was, but didn't you just buy that truck? How old were the batteries?

If you don't drive it often enough for enough time, you may need to put a charger on it once in awhile to bring it back to full charge. Just as an example, if you only drive it once a week for 30 minutes. If it's your daily driver to the base and back, then you are fine. If you only drive it to the train station and back each day, then you should charge it once in awhile.

It’s a 2022. Original batteries is what I just replaced. About 55k miles. I drive it nearly everyday.

Problem was, when we left for Florida last Friday I didn’t turn the headlight knob all the way. I was one click from off, so they stayed on for 8 days.

I hooked up the charger and one battery was taking a charge just fine but the other battery was dead. Didn’t and can’t really wait to see if the reconditioning would have worked. So I decided to just replace it.

I’ve always read that on two battery systems you need to replace both with same age and usage batteries. For the 108$ each (after my core refunds) I figured have two new batteries.

Texas' heat eats batteries and so does Nissan's power management so I typically get 24 to 30 months out of a battery. My truck was made in March '16 and I'm on my 5th battery, but only paid for 1:

Nissan labelled batteries. They have serial warranties and neither the 1st or 2nd made it to 36 month warranty so they were replaced for free. The 3rd made it past 36 months.

Interstate. My 4th battery (aka 1st Interstate) didn't make it to warranty and it was replaced for free but they only do that once.

I'm planning for my next battery to be a Duralast Gold AGM from AutoZone since it has a 48 month warranty.

I wouldn't if it didn't come off the factory floor with them. I tried AGM batteries in a couple of my vehicles, one truck and one suv, and they didn't last any longer or work any better than standard sealed wet cell batteries.

Also, AGM batteries use slightly different charging properties, so since your truck came with wet cell, that means the charging system was not designed for them, so you're prob better off without them.

If you buy good name brand regular batteries with same or higher CCA/CA ratings than what the truck calls for, you should do well. If you do just make sure you get the same Group Number, since that dictates size and cable configuration.

However, I might guess that dealer supplied GM units would be pretty good quality, but if you can get same or better CCA/CA for your batter size group number(s), if they are solid brands (not wallyworld etc.), you'd stil be gtg.

Also the longer the warranty period for full replacement (vice prorated, I think), the better quality.

It can be set to take AGM but a scanner is required. There is a lot of things going on with the newer models.
Old timers tend to think , just change out the battery and go, lots of parts stores still do it.
When I did it for a living, I had to keep up, now retired, no biggie.
I'll answer questions I know the answer to and leave it at that.

AI Overview
To properly configure your Ford F-350 to an AGM battery, you cannot do it using just the dashboard buttons. Because AGM and Flooded Lead Acid batteries require different charging voltages, you must update the truck's computer to ensure proper charging and maximize the battery's lifespan.

I've heard AGM recovers faster to full charge from short trips. So I've embraced them.

AGM is the same battery chemistry as standard batteries and can be charged just fine with a regular battery charger or vehicle charging system. Their construction allows them to be charged faster, but your charger or vehicle has to have that charging profile to begin with. If you just put an AGM battery in a vehicle that didn’t come with one, it will charge at the same speed as the old battery.

OttoSig, you did the right thing changing both batteries. I don’t believe you have to do anything special with your 2022. I believe the fancy BMS wasn’t used in the Super Duty until 2023. You can check by looking at the ground wires coming off the batteries. The fancy ones have a battery current sensor built in. I haven’t seen what it looks like in the newer Super Duty, but on my cars that have it, there are two small wires coming off of it that send information on voltage and amperage to the computer. It’s part of the connection to the battery terminal.

Sounds like a good choice.
I've got the AGM battery in my wife's Acura TLX Tech, because that's what is recommended.
Standard wet battery in my 4Runner.
