Battery saver 2nd battery

[Jmarler]

I got a cable and I was able to change it to 90% on the soc. Just drove it for awhile. I think it helped. It hasnt set off the battery saver mode yet. Its been almost instant right after i turn it off. So will see.

I have a hunch here that the BMS Sensor is false reporting data, and this is the reason for your Battery Save - Message
So, if the battery tests good and it has a Low IR then I suspect the BMS sensor, you may try a BMS Reset first - since it was not c/w with the battery replacement.
I would be curious what the BCM PID reads for the SOC as it comes from the BMS Sensor.
Note: Forscan will not display this PID


The System Off to Save Battery Message:
We know that the BMS Sensor (what it is reading) triggers this message, but I believe it's not really about the actual battery voltage reading, it's what the BMS Sensor is registering as the SOC reading.
This would explain why you have a good battery voltage test (12.2 Volts or Greater) but if you get this message (Check what the BCM is showing for the Estimated Battery SOC) this calculated reading comes from the BMS Sensor- it periodically updates the sensor while driving and performs a (True & Accurate) reading during sleep (rest)
Note: I think what is happening over time this sensor builds a (Drift Error) and reports false readings - throwing off the charging system and minimum error parameters that trigger the message.
Be it a - Sidetrack of the manuals and perform a BMS Reset, although there is only one Ford Document (GSB) that calls for a BMS Reset for System Error (T-Shoot) most of the document's state only with Battery Replacement
or
Replace as a precautionary maintenance item - depending on what your PID data is showing.

What do I need to read the pid? I have an obd reader. Currently have obd2 mx1 plus also but plan to return it

What do I need to read that did? I have an obd reader

It's going to be under the BCM - Battery PIDs - if the tool will read it, the PID is there but it depends on the tool if it will read the PID

Looks like im gonna replace it It went back to battery saver.

Now is the time to invest in the BatteryMinder Desulfator. Install it when you install the new battery. Keep your SOC high >=90, and turn off ASS in ForScan. Your battery will love you!

Personally, I'm leaving well enough alone. I have a good relationship with my dealer's service dept. and I'll rely on them to tell me when the battery load tests weaker.
I see the whole BCM/ASS/1300rpm shift points strategy as saving maybe an extra 200lb of CO2 from entering the atmosphere over the vehicle's lifetime. The BCM holds state of charge at 80% to enable the alternator to pull less power from the engine, as it has less load over a given time.
The ASS turns off the engine if all 13 of 13 parameters are met, then restarts the engine if one or more of those conditions change; most common is the brake pedal being released.
I don't have any empirical data, but it seems to me that, as the battery is discharging while ASS/off, especially if the lights, heater HVAC are all on, plus the lost charge running the starter, it will require more current, hence more load on the engine, to bring it back up to the 80%. than if it just kept running. How much CO2 is produced recharging the lost SOC vs idling for that time? Dunno.
Ford says that the ASS-equipped vehicles they build have heavy duty batteries and starter motors. Fine. But does that require more resources and energy to manufacture HD components than lighter duty ones? In other words, did more than 200lb of CO2 get emitted making the HD battery and starter for the vehicle? Dunno that, either.

Walmart told me it was still testing good at 12.5 but it's still going down to 12.2 after sitting. i decided to get a newer one anyway. I drove over to ford and see if they'll put in h7 in it. Going to keep there old battery.

Have 35k ford pass points

Do you have a picture of how you installed it? Im not very mechanical inclined when it comes to vehicles

To each there own. Going to a dealer is a good option for a lot of people.

First, lugging an engine at any speed leads to dramatically increased wear on all critical engine parts... think rod bearing, piston rings, etc. So does heating the engine above 180F. At 200F engine oil fails much sooner.

I've heard all the arguments about fuel / water vapor evaporating with higher heat, but the engineering truth is lugging engines and higher engine temps are attempts to optimize eco impact at the expense of reliability.

SOC for XL and XLT models is 70%. Lariats have SOC set to 75%. Having a battery that stays at 70%-75% is a recipe for short battery life. Sulfation of the lead plates begins well above the 75% SOC. Internal resistance of the battery will steadily rise and once above 5 mOhms becomes problematic but a quality onboard desulfator will still be able to break down the sulfar crystals covering the lead plates over time. At 10 mOhms your battery is not able to keep up and is on it last legs, and you're looking at a battery purchase soon. If you could look at a bell curve of battery life, you would see the failure rates much higher with SOC low in combination of increased load demands on a subpar charged battery.

Simply put, no matter the state of ASS, if your battery is charged over the SOC, the BMS will discharge the battery to the SOC. I have tested this and found it to be true. You can monitor the voltage and amperage rate dynamically and see the discharge happening in realtime. Batteries do not charge at 12.2v. Most charge at least a voltage of 13.5v. Auto batteries need to remain above 12.65v to minimize sulfation, and maintain optimal health.

Ford must consider AGM batteries to be heavy duty. I do not. I use them in all my vehicles. My 4G Ranger has one in it, and happily keeps it healthy (with the an onboard desulfator installed).

Soapbox On:

I'll not visit the pseudo science of CO2 warming, except to note that the planet is at one of its lowest CO2 levels in it's history. It has upticked a little bit, but it is far lower then average over the planets life. 2,000 years ago COS levels were much higher, and there was precious little industrialization to account for it. In fact, the rise of western societies flourished during this period. And this data can be easily proven.​

​

BTW, water vapor has 20 times more warming capacity on the planet than the same amount of CO2. CO2 makes up .04% of the atmosphere vs water vapor at 4%-5% depending on the region being measured.​

​

You are correct to question the CO2 cost of building / driving / manufacturing replacement parts that expire at twice the rate, such batteries and other components vs the CO2 benefit.​

​

I honestly don't think those analysis have been done, but if they have, they are being hidden from public view. I can't find any reports on the subject other than from "fringe elements" who question the CO2 narrative.​

​

And speaking of that, our entire manufacturing system is designed around designed obsolescence. The typical appliance now lasts 5-7 years vs 25 years 3 decades ago. How does this square with CO2 emission goals?​

​

We turn off electrical power plants in favor of "unsustainable renewable energy" while building massive incredibly power / resource hungry data centers.​

​

The powers that be at speaking out of both sides of their mouths. And us good doobies simply believe the trash they are spewing.​

​

Same goes for war... and its massive impact on CO2 emissions... We talk peace but stay in perpetual wars. I just asked chatgpt about US involvement in military conflicts...​

​

Here is the response:​

Years with no U.S. military personnel involved in combat anywhere​

Under this strict definition, the number approaches:​

​

0–5 years​

​

Because:​

• The U.S. has had overseas troops since at least 1798,
  • Has engaged in constant small-scale interventions, occupations, police actions, and special operations,
  • And has not had a single year since 1941 without at least one active military deployment involving risk of combat.

Many military historians argue the U.S. has had no fully peaceful year since WWII.​

​

Discounting the morality of these endeavors... Is this CO2 friendly?​

It is a Walmart Battery and has a warranty. Take it in and get a replacement.

 

[hughesjv]

I replaced my battery 2 years ago with Walmart battery that has 4 year warranty . The last few days my truck keeps going into powersaving mode. On my elo gps app. My volts go down to 12.2 after turning the truck off. So I ordered a charger and it gets here later.
Should I reset the bms after charging or leave it?

Im also considering to get forscan and change the settings. But the adapters are expensive. Would it help since the battery is 2 years old?

What I have assessed from all the posts here and with my own truck is that at least the Lariats have so many electronics that draw down the batter even when not used...if I go out of town for any longer than a week, I just hook up the charger or all the power savers will be activated when I get in. I guess luxury has a price...

George Carlin did many comedy routines about war, link to one of them but I also recall him doing a skit that employed dozens of phrases to describe war - regional conflicts, border skirmishes, police actions yada yada. And of course there was the Bob Dylan song " With god on our side "

Tried. Still test good on there test. Replaced anyway with different brand because I don't want to deal with it later. Kept the battery though.
