How to check 12V battery health… any tips?

Question
1

What’s the best way to check the 12V battery health? I can’t find any battery info on the truck screen, app, or Ford’s site.

I use a Bluetooth OBD2 adapter with the Carscanner app on my iPhone. It shows the 12V battery charge level, plus the high voltage battery health percentage and SOC numbers. You can even display it through CarPlay.

No problem, just passing on what I’ve learned.

This forum’s been super helpful for me since I got my truck a few months ago.

Good online communities make big purchases way easier.

Thanks to everyone sharing info!

I use Carscanner too. First time I checked, mine was at 75%. I don’t really get Ford’s strategy with the 12V charging… we see a lot of 12V battery failures. Maybe they’ll fix it with an OTA update… but yeah, not holding my breath.
