Super dead battery = electrical armageddon

[Tricky Mike]

Once a battery becomes dead, how does it get super dead?

Dead = can be recharged. Super dead = it's for the eels now.

Don’t ever let an AGM battery get drained, they won’t come back like a lead-acid battery. I just replaced my battery with a Duralast Platnum Elite AGM. This one has a 5 year warranty, the longest warranty I could find - most have a 3 yr. I started getting faults pop up on my dash, which is the first indicator the battery is beginning to fail. By not running it for 6 months, you wouldn’t have gotten the benefit of early fault warnings. If you’re planning on not driving it for more than 2 weeks, use a tender.

I disagree somewhat. My 2019 Transit has duals that I let die. But not for 6 months. NOCO charger plugged in and recharged. Been going strong for 3 years since. And I run hazard lights day and night and start and stop a dozen times a day. And an onboard inverter.

Did you reset the battery management system?

Only works at midnight on a night with a full moon.

My Bronco is my daily. Hopped in last Tuesday to go home from work and I get all the lights and warnings just like Tricky. It happened to me before, back in Oct 24 (car was 18-mo then). I disconnected the battery for a while and reconnected, poof, problem went away. Told the dealer, they said they did a software update and I was good to go. This time, did the battery disconnect and it did not work at all. Had to get it towed to the Dealer. They said they put it on a charger for 1.5hrs and no problems. They said there may have been an OTA Update and it could have drained my battery to the point where the vehicle would not start. This was last Tuesday, 3/3. Since then, since it was there anyway, they completed the rear camera recall and were finishing the Rear Shock Recall. They get it off the lift and, what do you know, all the lights and warnings appear again. The service tech calls me, said there are 3 modules out and they're troubleshooting it. Can this be a low battery issue or is it something more sinister?

Pertinent info: 2.3l, 7mt, Lux, 23k miles, delivery 12/22, FP Tune 08/24.


UPDATE: Shop called and said they found a lose ground wire. Tightened it up, no bubbles, no troubles. Wow. Sometimes, it's the little things.

I've been flirting with selling so I was avoiding putting miles on it.

Stumbled on to this thread. Been wondering where you've been. It would be a shame to lose a 6g institution, but as I recall you've got a B!! and OG to keep you entertained, Truck On!

I'm actually preparing for a move across country and liquidating a lot of stuff. The 66 will be the only Bronco left.

Sad to hear that! I was actually just looking for your tool kit. Do you plan to open shop again back east? Or onto something else?

I'm leaving my options open but probably not.

As far as the battery related issues, I haven't driven it more than a few feet since I posted but I've started it several times. No change yet.

My fords in the past had bad ground issues. It’s definitely my first check for gremlins.

Drove it today and it all cleared up within 5 miles except the park aid fault. Time to inspect sensors.
