Hi guys - I have seen in more than one post, that if you go into my trucks computer with Fords ids system, that there is a setting you change if you put in a AGM battery. True or False?

13 months ago I put in a 65 series AGM battery, and ever since then the system gives me the SYSTEM OFF due to battery condition once in a while.

If I need to have it done I will, but I don’t want to ask for a procedure that doesn’t exist.

Thanks for any and all help,

 

What year is your truck? Most batteries put into vehicles, especially those with stop/start feature have been AGM for years...that or Enhanced Flooded Battery.

 

2011 xlt 5.0

 

Your understanding is correct, assuming a 2011 has an AGM setting option. And a reset of the BMS.

 

You can't set AGM in the 12th gen, but you can, and need to reset the system either through Forscan or have a dealer do it through IDS so your new battery gets charged properly.

 

i did not have to make any changes when i swapped to an AGM in my '13. i simply had to let it sit for 8 hours (overnight for me) and all was fine in the morning. been running it for 2+ years now without any issues. no forscan, no dealer, no additional costs of any kind.

 

I hzd to put in a new battery bavk when i had issues with starting last year in the fall. dropped in a yellow top Optima and let her sit over night and half the day on top of that, no other issues at all since. maybe if batt is good, disconnect for a.while then reconnect and leave her be for 8 solid. wont cost you anything.. one thing i know for sure, youre on the right site for help. pretty smart folks on here.

 

The 8 hour sit *ONLY* lets the truck learn the current battery voltage, it does nothing else.

Inside your computers, it's got a ticking timer, and it shows how long since it was last reset, if this is the trucks first battery replacement, then that timer reads however many years old your truck is. The BMS is telling the truck that the batter is ~8 years old, and treating/charging it accordingly, which is less capacity. If you reset the timer, even now when the battery might be a few years old, then the truck will start charging it properly and extend the life of your battery.

 

my voltage meter and 2 year old battery sitting at 12.6 disagree with you. guess i was lucky and did not get an f150 with the super secret ticking battery time bomb.

i am not saying you are wrong, and i'm not saying you are right, but the 2013 owner's manual has the phrase "BMS" four times and they are all in the following screen shot. there is no reference to your "ticking time bomb", just the 8 hour rest and reset. it doesn't just check the voltage, it learns the battery state of charge, two different things. i think people may be safe. then again there could be a flurry of stories on the news soon about f150 owners suddenly having problems with their electrical systems all over the country. our trucks are 9-12 years old and i would imagine at least half of them have new batteries by now...

 

good.to know, ill call service mngr of Five Star and.ask if i got one of those BMS things..? ill also ask him what if any pkg.or.trim has that and maybe.some kind of indicator paper wise that designates that booger or not.
