  1. What gives? Bad battery leads to new discovery

    the important thing is not only to reset it to the right type of battery, and there isn't much difference between a agm and an enhanced, but there is. but more importantly you are reseting it to tell it that there is a new battery in the vehicle. with the new smart altanators and such the...

  2. What gives? Bad battery leads to new discovery

    Tbh, I don't know. As I mentioned above, I am not sure what effect (if any) the BMS system will have if the BCM is configured for one type of battery and another type is used. Based on my non-expert knowledge of the differences between a flooded battery and an AGM one, I don't see why it would...

  3. What gives? Bad battery leads to new discovery

    @rugedraw Can you provide any documentation on the effect that BCM Parameter has for these two cases: 1. BCM Parameter states: AGM but an EFB (battery) is installed 2. BCM Parameter states: EFB but an AGM Battery is installed I have seen documentation from Ford for the Bronco Sport that the...

  4. What gives? Bad battery leads to new discovery

    ...from FLD to AGM: I am not sure how much of an effect it will have in the system to put an AGM battery in a vehicle that is configured for an EFB battery. I can tell you that if it were my vehicle, I would make the FORScan change to reflect that battery type I am using because it is quick and...

  5. What gives? Bad battery leads to new discovery

    I have asked several dealerships, most stated they replace the battery with either type (AGM Battery or EFB), whichever the customer purchased and the dealership does not do any battery reset procedure or use FORScan of course and use none of the Ford tools - they stated (as does the owners...

    the EFB's will work fine, just won't last as long. that would be your normal 3 to 5 years as oposed to the 8 years + of a agm.

  7. What gives? Bad battery leads to new discovery

    There is only 1 module in Forscan to change the battery type. I just changed my daughters AGM in her 17 Fusion, original battery. My EFB lasted under 3 years..... There are numerous reports of early failed EFB batteries, issues with electronics due to the battery, etc on this site. My OPINION is...

  8. What gives? Bad battery leads to new discovery

    Well had I done a manual BMS reset and not via Forscan I would have never known that Ford had the wrong battery type programmed in the BCM.

  9. What gives? Bad battery leads to new discovery

    ...did read your post and I stated “ You can do either a manual BMS reset or reconfiguration via FORScan “ and at that point whether you switch from EFB to AGM Battery or from AGM Battery to EFB all is good whether or not you later go check and see “the wrong battery type” reflected in one or...

  10. What gives? Bad battery leads to new discovery

    I also have an EFB battery installed, and the AGM parameter was also set in Forscan. Changed it to EFB.

  11. I'm thinking about changing the stock battery to a AGM type battery

    You might be right about Your last sentence and see the Thread You started to see what I posted.

  12. What gives? Bad battery leads to new discovery

    FWIW the 2023 BS BB I had and bought brand new in December of 2023 had the EFB battery in it!! I was afraid many times in the cold weather it wasn't going to start so I hooked a charger up over night sometimes which you shouldn't have to do!! But it was never dead when I did that and traded it...

  13. What gives? Bad battery leads to new discovery

    Found the thread discussing this, very interesting. I wonder if all these battery issues, premature failures and the such are because Ford left the BCM type as AGM when they used a EFB battery????

  14. I'm thinking about changing the stock battery to a AGM type battery

    2023 Outerbanks. Dead battery today at 38k. It was the EFB. Replaced with Everstart AGM. Went to change the battery type in Forscan and it.was set to AGM from the factory.....so I did the BMS reset and hope to get good service out of it. Wonder if all these battery issues are because Ford left...

  15. Strange issues

  16. Cost for battery upgrade to AGM

    Dang it my experience was very much not that haha. I’m a bit of a pushover cause I am not good at interacting with people so I just simply stated “I replaced my original battery with an agm last week and just discovered there was a recall, ford said if I’m looking for reimbursement to come to...

  17. Cost for battery upgrade to AGM

    Ohh Okok I get it now. Thank you 🙏 that makes sense!!

  18. Cost for battery upgrade to AGM

    ...you did not get the recall which is because your VIN disqualified your vehicle from the recall Because you stated your vehicle came with an EFB (Battery), that battery was not subject to the recall. According to what I read, it’s a specific EFB made in China which apparently your vehicle did...

  19. Cost for battery upgrade to AGM

    I don’t understand why you didn’t qualify. Mines a 2022 that is 6 months beyond warrenty. There were no questions asked. Maybe call Ford again.

  20. Cost for battery upgrade to AGM

    I’m probably “beating a dead horse”, but here it is: EFB failed post 3/36 warranty on my ’21 BS, and was replaced by dealer with AGM. I paid for the new battery, then the recall was announced. Dealer said they would attempt to get me reimbursed after batteries were available and the recall was...
