What is the Best Replacement Battery For Your F-150 PowerBoost?

[@eliedube]

Have the same problem in my 2022 pwrboost. Found there is an extra battery located under the rear right seat connected in parallel with the front battery. Another thing to consider is if you plan to recharge the battery... never put the negative clamp directly on the battery... put it before the bms sensor or on the frame. Even fully recharging the battery directly on the battery pole, the bms will still warn you for a low battery. The bms need to record the actual amps that goes into the battery in order to make it work. The bms is in deficit of amps, so it will still display low battery and in safe mode.

I have a 22 F150 with the Coyote V8. In the colder months, I've heard the weird chiming you mentioned. Thanks for explaining that mystery. Living in the South, I don't get winters below 50 degrees. One thing I learned is that the BMS is an important part of making sure the truck's BCM is able to accurately measure the battery SOC, voltage, and temperature. The BMS sensor is the little black box attached to the negative battery cable. When charging the battery, you need to make sure you have the negative clamp on the vehicle side of the BMS by not connecting the clamp directly to the negative post. You also should reset the BMS after charging or changing the battery to allow the BCM to relearn the battery SOC. If the BCM does not relearn the battery SOC on a properly charged battery, you'll get false warnings from the BCM including the truck not lighting up when approaching, the weird chiming, power save mode warnings on the infotainment screen, and other odd behavior. Resetting the BCM can be done by powering on the truck, but do not start the engine. Wait for the battery warning light to illuminate. Flash the high beams 5 times, then press and release the brake pedal 3 times. After about 10 seconds, the battery warning light will blink 3 times to indicate that the BMS has been reset. If your battery is good, this should eliminate the false warnings. If not, replace your battery.

[@machine7767]

I am having a similar problem with my 2022 EcoBoost (Non-Hybrid). I have to charge the battery once a month when I get the warning then I am good for another month. From what I have read online the ECU only charges to about 80% then slowly charges more after that. Supposedly with FORSCAN you can edit battery charge level and change it to 90% and it fixes the problem. Will be curious in a year from now if your new battery has still fixed the problem or if you are back to where you started. I have also read on the non-Hybrids you can fit a larger group 49 battery in there although the blanket around the battery may not fit anymore.

Thanks again for a nice video! I’ve had decent “luck” extending the life of my battery by charging it quarterly. Currently I use a 10A noco charger and it seems to do a nice job, quickly. I’ve also noticed the SOC will drop rather low but if I run the hvac fan level 6 or max, the truck will kick the charge up to 14.4. I thought it was a strange thing, but it’s been confirmed by many to be the case. Last summer I tried to make my truck less able to be stolen when my wife’s key (and purse) were taken on vacation. I took the battery cable off and found the key fob still unlocked the door and for fun I found I could start the engine with the battery essentially removed. I did get an error message to check my charge system. 😂 It was a sleepless night thinking someone would stop by to take the truck! Anyway, this charge system is very different in this truck. I’m not sure anyone has a complete understanding of it outside of the engineering department at Ford.

[@fixorrepairdiy4609]

Some guys have actually installed flexible solar panels on their hood to passively charge their low voltage batteries for the same reason.

[@brucesummers7448]

Dealers will replace the H6 battery with the same and not a H7 that is provided only with the higher trim level trucks. The Ford Battery Management System does not work well at all in preventing high levels of discharge which is very damaging to flooded lead acid and AGM batteries. Best to go with a battery like the Optima that is designed to function as a "deep cycle" battery and so should be better able to withstand deep discharging. One should also plan on using a good battery maintainer like the one from Schumacher with its 1.5 amp trickle charging.

I have '23 Powerboost and i have had the low battery warning 3 or 4 times so far (bought it in early february 2024). I have started putting it on a battery tender once or twice a week overnight (gets to a fully charged state). I only drive about 5 miles a day during the week (or somedays not at all) and usually a trip into town on the weekends which is 20 miles each way. Even with the charging once a week i still got the battery message days later. From your experience - do you think replacing the battery with a high quality one will fix my issue? Or is my mileage just too low to every keep the battery appropriately charged without topping up via a tender? Thank you for any advice. By the way - I have watched all of your powerboost videos and I really appreciate the in depth information as I am a mechanical engineer and appreciate data driven decisions. Keep the videos coming!

[@fixorrepairdiy4609]

Kevin, it might be a little of both. (weak battery + not enough charge time) See if this improves during the warmer temps, and consider getting a bluetooth monitor to keep an eye on it and see what kind of passive discharge that you get overnight. Most people with this issue had it go away with replacement away from the OEM battery, so it might be just a bad batch of batteries during 22/23 builds. So much of this is speculation right now. All I know is that my voltage spreads are "tighter" with the new battery. cheers

Battled this all winter here in Kansas. Dealer was worthless but to be fair I am sure Ford tied their hands. I did exactly as you did, right down to the same replacement battery. No issues since the change. Thank you for another great video. I totally enjoy what you have to say and the reasoning behind it. The other thing I am researching now is the poor fuel mileage I get. (15.8 to 17.6 mpg) over the last 6 months. Granted I put 33 x 12 tires on it and that alone maybe the issue. However, I have never gotten over 20 mpg since I purchased it. (new). Trust me I have been so light on the pedal I was getting passed by Amish horse buggies…. Keep up the excellent work and thank you! PC 😊

[@fixorrepairdiy4609]

Paul, did you recalibrate your tire diameter in Forscan? Can you verify that your speedo/odo is accurate via GPS or a known measured distance? I've heard of lots of folks having the same issue when they changed to larger tires. If you think about it, the circumference is larger on a 33 vs. stock so the truck thinks that it's not traveling as far for the same amount of fuel expended. Fatter, more aggressive tires will certainly show more rolling resistance, but I think your root issue might be calibration. Also you will take a hit over the winter with an HV battery that takes a while to be warmed up and provide full current, plus winter blend fuel lacks the equivalent amount of energy vs. summer blend. cheers

22 PB Lariat owner here…has anyone else noticed a link between battery voltage issues and the car defaulting to using the conventional/backup starter to start the engine vs the electric drive motor? My dealer swapped out the factory battery a couple months ago under warranty. Over the past week or so, I’ve noticed a sudden/regular use of the engine starter to start the engine on the initial cold start. My understanding is that the conventional engine starter is in place in case the state of charge of the high voltage hybrid battery is too low to turn the engine over. Since this truck is so damn complicated, I wonder if a voltage issue on the 12V battery might somehow be connected to this sudden use of the starter. I would guess low voltage on the 12V battery would result in a decreased ability to use the engine starter? 🤷‍♂️

[@fixorrepairdiy4609]

The primary "cold start" method is the belt-driven starter; if you've ever been sitting in a parking lot with the truck on and heat or A/C on, the ICE will kick in from the BDS and the truck will rock, or "torque" from this starting event. In 2.5 years of ownership, I have only heard the Bendix/Flywheel start method used maybe 3 or 4 times. And yes, only when the state of charge of the 12V battery is low. I would suggest monitoring your 12V battery using the bluetooth device featured on this video and see what the difference is between overnight resting voltage and full charge voltage. When my 12V OEM battery got weak, overnight voltage would drop under 12V on "wake up" and the DC/DC converter would run up to almost 15V on full charge. No wonder I was blowing out tail lights.

Well, I took your advice and bought the Bluetooth battery monitor, and now based on the monitoring I just ordered an X2 from Batteries Plus. When I installed the monitor, however, I noticed that the original H6 battery had been replaced by a FoMoCo H7 (the original battery blanket apparently didn't fit and was torn leaving a large gap in the blanket on the side). A couple of questions: 1. I noticed in your video that your battery blanket appeared to fit your new X2 battery. Did you replace it with a different blanket or was that the original blanket? 2. I know you said you reset the BMS after replacing the battery, but did you make any modifications to the charging level using Forscan or do anything to let the vehicle computer know that the new battery was an H7? If so, what did you do specifically? 3. When I installed the battery monitor, I experienced some sparking on the positive terminal when I loosened the small top attachment screw to seat the positive end of the monitor (the post clamp was not loose and the negative end was isolated and did not come in contact with anything). Did you have that experience and was there a particular removal sequence you used for the various accessory connections to the battery terminals?

[@fixorrepairdiy4609]

Hi Michael, I'm not sure what engine you have. A PowerBoost should use an H7. 1) Original blanket 2) Original battery was H7 so no changes made in ForScan. 3) You should experience some sparking if the PowerBoost Aux battery is at a different potential than the primary 12V battery. If you don't have a PowerBoost, then you might have some passive draw somewhere. I usually disconnect positive terminal first, ground last, and assembly is reverse of disassembly. cheers

[@michaelstaudaher3308]

I have a 2021 with a PowerBoost engine. I bought it used just a couple of months ago. I thought from the various F150 threads I have read that the original battery for the 2021 model year was an H6 instead of an H7. The blanket around the battery in my truck definitely is smaller, hence the tear. The aux battery is the original and is the smaller 12v (BXAGM-Aux1-B).

[@fixorrepairdiy4609]

@@michaelstaudaher3308 OK, perhaps the 2021 models had an H6. I think that was standard for the "regular" ICE engines like the 5.0. The newer ones are definitely H7 and some are trying to wedge an H8 in there with challenges. I don't think an H8 will fit in a PowerBoost due to the space available. The H7 is essentially compatible with the 94R battery spec so depending on the battery store that you go to you might find either one, although the 94R is slightly stronger spec electrically.

Looks like you tested the new battery while disconnected from the vehicle. Did you test both the main battery and the aux battery at rest and while disconnected from the vehicle? As you know, the Powerboost has two 12v batteries connected in parallel, acting as one battery. So, a single volt meter or battery monitor connected to one of the batteries is always reading both batteries. If the aux battery is bad and you install a new main battery, the old aux battery will simply degrade your new main battery and you'll be back to where you started. (I'll be changing BOTH batteries later today. I'll be installing an 800 CCA main battery with 160 minutes reserve capacity and a 14 Amp Hour aux battery. The OEM aux battery is only 7.5 Amp Hours.

True, but the aux battery's only use is to keep the electronics powered while cranking. I could take the time to test it separately (off the buss) but being that I've had no issues show up during cranking, or since I replaced the primary 12V battery, I'll give it a pass for now. cheers

LiFePO4 batteries are cheap enough, but the cheap ones are unsuitable for a starter battery replacement. I've been doing some experimentation with adding a LiFePO4 battery and a DC:DC charger with some circuitry so it will support the lead acid and keep it fully charged at all times. The starter will draw only from the lead battery, then when the engine is running the LiFePO4 charges in a controlled manner. And on a closely related topic... I'm annoyed at Ford. The powerboost apparently has 3 ways it can start the engine. One would be sufficient. Why the redundancy and why does everything stop if the main 12v lead acid battery is weak? If they eliminated the traditional starter (no more huge draw) and ensured controlled charging for the main 12v battery (no high amp or high voltage charging) then it could be replaced by a LiFePO4 to achieve weight savings, endure long non-operation times, and nearly indefinite life.

[@fixorrepairdiy4609]

I'm trying to figure out the three different starting methods. I get the ICE start based on the motor/generator (bump start), plus the start from the belt-driven starter up front, but the third bendix starter is a bit of a puzzle. I *believe* that third method is only used if the bus voltage from the DC/DC converter is too low to support the start logic to drive the BDS. Then it turns into a 1942 bendix "chew-chew-chew" starter on the flywheel which allows the motor/generator to spin enough to charge the HV battery. But your post is the first time that I've seen "LiFePO4" used in a sentence. cheers

[@Sylvan_dB]

@@fixorrepairdiy4609 Yup, I cannot figure out Ford. Sorry if LiFePO4 was confusing. Batteries have been a large part of my life for many years. Lithium (Li) iron (Fe) phosphate (PO4) is a less expensive and much more stable lithium battery chemistry, which has been gaining a lot of popularity for energy storage where those factors are more important than the slight increase in size and weight compared to the more familiar lithium nickel cobalt manganese (NCM) batteries common in portable electronics (cell phones, ...) and most battery electric vehicles (both two and four wheeled).

They had it a week and said they found no voltage leaks. I have the same battery monitor so I need to install it and compare old to new voltage range like you did.

[@Sylvan_dB]

The battery core charge is annoying... I have ended up with a few spare batteries at home that need to be recycled, so I'll take one of those in when I go to buy a battery - core returned and new battery in one trip. Without that, and on a bright enough day, I'll swap the battery in the parking lot.

Is that battery AGM that you installed? I saw it said lead acid in the corner

[@fixorrepairdiy4609]

Yes, it's an AGM battery.

[@justinwinkelmann2881]

Flooded, AGM, and Gel are all types of lead-acid. The electrolyte (sulfuric acid solution with water) is either sloshing around (flooded), Absorbed in a fiberGlass Mat (AGM), or in a Gel.

What is the procedure to reset the BMS Monitor?

[@fixorrepairdiy4609]

Turn the truck on to "accessory." Flash the headlights 5 times. Then press the brake pedal 3 times. The battery icon will flash 3x to let you know BMS has been reset.

Is it possible to put a Lithium battery in?

[@fixorrepairdiy4609]

I am just passing along information as I'm not a battery expert....so take this for what it's worth. I hear that Lithium batteries have difficulty with charging in cold climates and might require external or internal heating.

[@jblaze114]

wait, theres a 12v battery for the starter? if its a hybrid, doesnt the hybrid battery start the engine? since the car is technically on and driveable, thats wierd.

[@fixorrepairdiy4609]

There are actually three separate batteries. The 21 - 23 PowerBoost engine is started in three ways: 1) belt-driven starter, 2) "bump" start via the electric motor while vehicle is in motion, and 3) a typical bendix-type starter on the flywheel. The 24 models eliminate the belt-driven starter.

[@mt_9076]

Should you not have removed the negative first then the positive terminal ? And then Install back on positive first and tighten clamp then install the negative terminal and tighten ? Good vid other than that 😉.

[@fixorrepairdiy4609]

Interesting. I just did a little bit of Google-Fu on the term "which terminal first" and it appears that you're suggesting the conventional wisdom of removing the negative terminal first. Everyone parrots the same advice across the Internet, however nowhere did it explain WHY other than to suggest "that it would cause a short if you do it reversed." Which, of course, is preposterous. I stand by my method of always ensuring that the ground connection is made first to any source, (and then connect the hot) unless someone with an engineering background can tell me why that is wrong. In home wiring you always connect ground and neutrals first, before tying in the hot. How is this different? 🙂

[@kingstonsean]

@@fixorrepairdiy4609 If the battery is grounded and your wrench accidentally touches anything metallic as you are attaching the positive cable you will get a free light show.

[@rangerbrown]

You have forgotten the other 12v battery that actually runs the welcome lighting ect...

[@fixorrepairdiy4609]

Nope, did not forget. That battery only comes into play to keep the electronics stable during starting events.

[@rangerbrown]

@fixorrepairdiy4609 recommend joining the 14gen group and read up on that. It does way more and is tied to the hood battery. Also change the soc setting so this does not happen again. Factory setting is 60%

[@fixorrepairdiy4609]

@@rangerbrown Yes I know that it is tied to the primary 12V battery. But it does not "run the welcome lighting" per se. Perhaps my wording on the reply was confusing....the primary purpose is to keep the electronics stable during cranking, where it is actually relayed out from the primary battery during that process. I am a member of that forum and do not recall any discussion of the secondary battery function besides this. cheers

[@randyschultz6594]

Battery voltage alone is not an indicator of the state or health of battery for Lead Acid battery technology. The nominal voltage for a lead acid is 12v which you will see on the battery datasheet from the manufacturer. It appears you just replaced a good battery.

[@fixorrepairdiy4609]

Thanks for your comment, Randy. In my 40+ years of experience with automotive batteries, resting voltage has always been 2.1V/cell or a nominal resting voltage of 12.6V at full charge. AGM batteries have slightly higher resting voltage at full charge. Here, let me google it for you: "What voltage should an AGM battery sit at? Even for 100% - some charts state that 12.8 V is 100% full, others show 13.0 V as full. This difference of opinion happens because, although a fully charged AGM battery will be close to 13.0 V, the voltage drops very quickly to 12.8V. So 12.8 V can be considered to be “fully charged”." Since I changed out my "good battery" with the new one, I have not received any further warning messages from the truck's monitoring system. So per my video, the battery voltage falling below 12.0V overnight is an early warning that it's not holding charge very well. JMHO sir.

Few times in these 2 years I’m owning f150 (bought new in 22 with 5.0) I would push the start button and it would not start,and usually after driving from work and quickly stopping at the gas station Weird

[@fixorrepairdiy4609]

Hi Josip...sounds like it drained overnight and the short trip took more charge out of the battery than was replaced by the alternator. Perhaps time for a battery check, or use one of these bluetooth monitors. cheers

[@kschroll666]

Your battery isn't covered under the warranty. I bought an H8 and then used a Forescan tool to change the charging capacity from 80% to 95%

[@fixorrepairdiy4609]

Nice work. I have seen some folks get covered under warranty for the battery, but it needs to be bad enough to actually throw a code.

What year model is your truck?

[@enriquesuarez3961]

It’s funny how you say you can get stranded hello it’s a hybrid truck when it’s starts it’s in hybrid mode so your hybrid should be charge Unless your truck is having problems with your hybrid batteries then yes be worried about getting stranded Now about having more cranking amps it’s always good but that’s all across the board with any vehicle Well have a great day and make sure your hybrid battery is in good working order to avoid being stranded as stated

[@fixorrepairdiy4609]

Enrique- your hybrid battery in the PowerBoost will only take you a very short distance before it's discharged. If you can't start the 3.5L gas motor, you're not going very far. In fact, the truck's software will figure that out and put you in "limp" mode. So you must have a decent 12V battery to start the ICE even though it's a hybrid. Cheers

Dude my motorcraft battery lasted over 7 years I finally changed it cause it was so old

Yeah I think FoMoCo had a lousy batch of batteries that were made from 2021-2022. Seems to be isolated to those two years.
