Do I have a bad battery?

[hamrhed1]

I received warning messages on the dash for my issue. I have a PB so no start/stop,, only when it goes from Elec to gas

I do not get any battery warning or experience any voltage error. The only thing that does not work is the auto/start stop. I know everyone hate this and I do too. I am just worried if the battery or alternator going bad

Replace your battery.

Replace your battery.

Is the battery under warranty? My truck is 2022 with 21k miles with Ford ESP Warranty
I can buy another one. Also Is it possible to put a larger battery like H7? Thanks

I have a 2022 and just had my battery replaced under warranty. In 1st half of 2023 I had a fair bit of issues with truck going into low power state. Had dealer check it and they said everything was fine ?. With help of this forum I charged the battery up and reset the BMS. I didnt have any issues with low battery state even when it sat for up to 10 days - and started getting OTA updates. Few weeks ago had the truck go into low energy state. Mentioned to the dealer this week when I was in for an oil change. This time "yep your battery is an issue and we replaced it under warranty". ?

So I re-charged my battery to full last night. I measured the voltage 12.3 on the battery. The Auto Start/stop is now working. Does this mean the battery is bad OR it means I do not drive the truck long enough?

Mine behaves the same way. In fact, after a drive from Memphis back to DFW, a few days later auto start/stop didn't work. So, I put it on a charger and start/stop worked again.

From what I have read on here, our batteries are on the way out.

Observations. I have now let my truck sit for 5 days. Terminal voltage is now 12.53VDC with an ambient temp of -2ºF. We'll see what develops.

Before the expense of a battery it might be worth doing a full recharge and then resetting the BMS. You can find on the forum or you tube how to do the easy reset once battery fully charged.

OK I am just reporting back. After a full re-charge. Auto start/stop works. It's been 2 days. Its about 14 degrees in MD. I did not do BMS reset or anything.
