H7 Upgrade - Battery Felt

[Ext1809]

I ran across this several days ago about replacing the battery felt on an upgraded H7 battery (replacing an H6). Someone had posted the part number from Ford and I would like to order one since we now live above the snowline.

Of note, I measured the battery tray before the upgrade and I did not have any problem unhooking the BMS or any of the positive side wires that had to come off. It was a straight drop in. I would like to put a new battery felt wrap on to replace the H6 one I took off. I went with the EverStart Platinum AGM from our friends at WalMart.

I do believe this is what you may be looking for. Ford part # KB3Z-10A687-A

Got two warnings today on my screen about powering down to save battery.
2019 with 60k, pretty good for the stock battery IMO.
Better start shopping I guess.

I purchased the same battery. Reach out to Benny@Levittown on here, he will take care of you. Lot better pricing than my local dealer.

I upsized the battery on my daughters Hyundai and just cut the wrap at the smallest corner and put it back together. I don't think a 1" gap will make much difference. Slap some ducttape on that b1tch and call it good.

so when you change a battery on these trucks, do you also have to get into the brain and change charging settings??

I found the manual way of resetting the BMS; key in the "on" position (not started) flick high beams 5x and step on brake pedal 3x, wait 10 seconds and battery icon flashed 3x and we were good. The other way that I learned, was after driving it around, let it sit "asleep" for 8 hours. I found this YouTuber who helped. https://www.youtube.com/@FordBossMe

$178 at WalMart, $12 core charge. $208 out the door. I did use a step stool for better advantage to getting it in.

BMS -Reset
The only true way to do it is via Scan Tool or Forscan for a True Valid confirmation that the action was completed by a visual message and the Time Since Installed Date - changed to current date

The alternate way - Headlight / Brake - has not been a confirmed way to do it- your only indication is that battery light going off.
This procedure is not in any Ford produced written material.
Now it may work - IDK, but I have not seen anyone do it and then use a scan tool to confirm the Time Since Install Date change

Drive it and leave it - Automatically Learn.
The BMS can register the battery voltage change and set the charging voltage to the current battery state , this is exactly what the system does , so this procedure is the same as putting the battery on a charger.
It cannot however know the battery is a new battery and change the Time Since Install date (Automatically)

So, the point I am making is - The Time Since Install Date is a piece of the BMS charging algorithm that determines charging system output to the battery.

Here is a Excerpt from the Ford Patent for the BMS

A battery monitoring system (BMS), which utilizes a minimum amount of input data (time, voltage, current, temperature and conductance, for example) to periodically determine a vehicle battery status or condition is provided. The BMS combines electronic hardware and software to give logical and critical data to assess and control a battery-based electrical system. The BMS can include processing circuitry (a microprocessor, for example), which is coupled to a voltage sensor, a current sensor, a temperature sensor, etc., that provide the necessary input data for the microprocessor, which executes program code, to determine the vehicle battery status or condition. A method of monitoring a battery in an operating vehicle is also provided.

From my in-depth Charging System Thread:

As the battery ages the internal resistance increases, and the system counteracts that resistance by increasing the charging voltage to overcome it, so overtime the system is fighting hard to charge the battery but it still is monitoring the battery temp while charging thus backing off charge voltage as the battery will get hotter due to the increased internal resistance. So if this option is true, when you replace the battery without performing the BMS reset, then you will be overcharging the battery because the Algorithm has been set to charge it that way.



Does it truly make any difference if you do not do the BMS Reset?
IDK, not enough data to actually know for sure.
I just know how the system is intended to operate and the Time Since Install date is what is actually being changed when a BMS Reset is performed and it alters the programmed data the BCM has in (Programed Data) to force a date (Change) the date into the BCM.

The system knows what a (NEW) battery internal IR and Voltage is by a programmed software data input and uses that as a data parameter.

hat tip to @airline tech:

When I did the headlight / brake, I did receive what I would define as a confirmation blink 3x from the battery light indicator. And to add to that, my truck is also sitting for the 8+ hours "sleep". I do not have a Forscan tool (yet). We shall see.

But I do appreciate all of the information you have given and will continue to lean into your knowledge given as I know my limitations.

When I I replaced my battery a while back I did the Konami code method. When I checked in ForScan later, it showed my battery in-service counter had reset to zero.

I also received the blinking from the battery indicator as confirmation.

Cool - so it does work - Headlights / Brake Pedal

I had the Atari 2600 - Before the NES even existed, that was the gaming system to have back then.
as my kids became of age to play, it stated with a used NES and progressed up to the GameCube.
Atari - had its own easter eggs but nothing like the Konami Code's for Nintendo.
They would come home from school and boast about a new secret code for game play to try.

I essentially did that. Zip ties through the felt to keep it seccured tighly around the battery. Its such a tight squeeze its more so it didn't slip out of place when dropping the battery in but i cant imagine it coming loose now and doubt the small gap will make a difference

I've been tempted to do the same, but found I can do all of it in Gnome Boxes running DOS, Win3.1 and WinXP. I run all my very old arcade, DOS, and Windows games. Most of the old Atari and Arcade games were ported to DOS and early Windows versions long ago.

I still like all the old Command and Conquer games! I can even network them in the DOS and Win 3.1/ XP versions running in Boxes.

All this said, there is still something special about pushing those big red buttons, or the flapper paddles on the sides of an arcade game console.
