How about a scenario where you replace the standard flooded battery with an AGM type?
I have seen somewhere that there is a place to identify the type and CCA in the vehicles software.

My '17 F150 xlt has an H6 610 CCA motorcraft batt on its last leg

I want to install an H7 800 CCA AGM battery from walmart (I can see that an H7 will fit the battery box handily)

Is there a way, perhaps using forscan or forscan lite on an android phone to change the battery type as well a a BCM reset?

 

I installed an 800CCA AGM battery in my 2016 F150 platinum supercrew 3.5EB today as a replacement for my original battery that was a 760CCA that appeared to be a lead acid.

I took it to the parts counter and compared them, they were exactly the same size. The replacement was easy, and no battery lights or messages came on after replacement. My radio presets were kept, even though I was disconnected for about an hour or so.

I did the procedure another poster listed, with accessory power on I flashed the lights and pumped the brakes the appropriate number of times. I did get the battery light flash. Everything seems great.

my previous battery had not failed, but when I tested it it was down to about 450CCA, so I replaced it preemptively.

New battery tested at almost 1000CCA, so way over the rating.

The battery part number from Ford was

BAGM-94RH7-800

 

Yes, that's exactly what you need to do. Use Forscan to change the battery type and then initiate the BMS reset.

Ignore the post above... the flash lights/pump brakes/etc. doesn't work, per stormsearch's previous posts (and he's kinda the expert).

 

Ignore the poster above, it worked great for me, on an actual truck, today in my driveway. 🤣

There’s lots of so-called “experts” on the internet, but sometimes you’ve just gotta get your hands dirty! I figured Ford wouldn’t make it too tough to change a battery. 👍👍

 

I'm basing my knowledge on having modified several F150 electrical systems and having sought the counsel of @stormsearch - who is actually a Ford engineer developing the battery and charging systems on these trucks.

But yeah, I'm sure your sample set of 1 and zero expert insight is better.

 

Yeah, well I stayed at a Holiday Inn Express last night!

 

So here is the jist. The Manual procedure does work. I was told by my calibrator a couple years ago that for US vehicles it was disabled. However, last year was able to finally get into our work garage and do some testing. The manual procedure is enabled on newer F150's. Talked with our new lead calibrator and received some better insight on what the reason was for not providing this information beforehand. The issue in having a manual BMS reset procedure is it allows both the assembly plant and selling dealer to immediately reset the BMS SOC and deliver as good when essence, the battery could be good, partially bad/weak, or on its last leg. Ford has requirements on battery quality/SOC before being shipped from the plant and as a selling dealer. A BMS reset bypasses that and can create a disgruntled consumer.

So with that being said, I have pushed to get the manual procedure added to the owner manuals for vehicles the manual procedure is enabled (which is nearly all Ford vehicles except a few). Ensure the battery light flashes after doing the procedure. I could not provide this detail earlier as it was not public information. There is much more to the BMS operation, differences between MY's and vehicle lines that I can provide. I have stopped sharing information because it can lead to false presumptions.

Another item that I have tested was the BMS able to learn on its own a new battery has been installed. There are algorithms in the BMS for the more likely case that a consumer replaces their own battery and not perform a reset. It is not an exact timeframe, but around the 3 week mark after replacing with a new battery, the BMS will know a new battery has been installed and will reset. Note, testing was only conducted with as built batteries. Replacing with another type of battery may delay or incorrectly set a different of the actual battery.

The one advantage of performing a reset are for vehicles that have the "Vehicle Shutting Down to preserve Battery" message. If the BMS reset is not immediately performed with a new battery, the BMS will continue to protect thinking the old battery is installed.

I want to end by saying, Ford requires the dealer to perform a BMS reset as we pay for the replacement cost and warranty that work. We don't require a consumer, auto parts store or anybody else to perform the reset. In the big scheme of things, performing a BMS reset is minuscule to how the battery was manufactured, lot rot, vehicle drive conditions, vehicle issues, added equipment and maintenance. I replaced my OEM battery with a non-OEM, same size H6 AGM from Napa. I chose that battery due to the mfger. I did not perform a BMS reset. It is simply not that important.

I had mine reset this summer when I put a new battery in…2018 model year.

Went with a yellow top. I know I know. Some say they aren’t what they used to be but I paid under 250 brand new.

 

Excellent!!! LOL!!!!!!!!
