Battery Maintainer/Tender and Battery Management System.

[Owl]

I'm about to charge my battery after sitting for a couple of weeks. Looking at a chart it looks like its at 12.2 volts which equates to 60 percent.

My question for anybody that knows... is it possible to hook a tender to the Bronco without disconnecting the negative terminal?

In the Bronco owner's manual it states the following, and it sure seems like a lot to have to go through to keep the battery charged up.

Anybody have experience with this???

Battery Management System Limitations

After battery replacement, or in some cases after charging the battery with an external charger, the battery management system requires eight hours of vehicle sleep time to relearn the battery state of charge. During this time, your vehicle must remain fully locked with the ignition switched off.
Note: Prior to relearning the battery state of charge, the battery management system could temporarily disable some electrical systems.

I have a tender on mine and it works great. I do not disconnect.

No problems with the electrical system on the Bronco? That is -- it just works, and no problem with the Bronco having to relearn anything?

Remember that the 6G Bronco battery is an AGM type. Make sure your tender/ charger is compatible.

I picked up this one. It has excellent reviews and is at the top of many "best charger" lists. https://www.amazon.com/dp/B07W8KJH44?psc=1&ref=ppx_yo2ov_dt_b_product_details

I believe that references charging a battery out-of-the-car, but I'm willing to be corrected by someone who knows with more certainty.

I used to attach it with the alligator clamps at night during winter. I wasnt driving much. This season i might just bolt on a permanent lead.

ANYWAY, you can clamp the red pos lead to any available pos terminal space on the battery BUT for the Neg black lead you want to clip or bolt that lead to the far end of the battery minder attached to the negative terminal, so the charge runs across the minder. There's a metal tag to the right of this that I always clip onto.

Bronco has battery maintenance system that you don't want to bypass when you charge battery, that's why you don't charge directly to negative battery terminal.

Others can explain more. There's a video around here too I'll try to find

100% correct. There’s a YouTube video that shows this on the F150 with the same chip.

Yeah, I can't find it... lazy and I didn't save it. Maybe others have it. It was good info

Had no issues with AGM or lithium with mine.

I was just talking about this in the Forscan thread...which I guess in reality is inappropriate. But, this is my setup: https://www.bronco6g.com/forum/threads/2021-bronco-forscan-thread.844/post-2049079

Thanks in regard to the video (minute 13) on how to properly connect a battery charger/maintainer on the other side of the negative sensor so that the Ford battery monitor system can register it.

Much appreciated.

I put my Bronco away for the winter and use this battery maintainer all winter.

There’s a battery measurement sensor doohicky on one of the terminals. Just have to make sure that you connect outside that sensor so it gives you an accurate power charge level. Otherwise, 10/10

I have one of these on my RV AGM battery. Still going strong after a number of years outside in Texas. Happy with the product.
