Plug in to Maintain 12V Battery

[Mach-Lee]

FYI if you wanted to check your 12V % level, it's your lucky day because a bug has caused the 12V SoC to become accidentally visible on Ford's account dashboard here: https://www.ford.com/myaccount/account-dashboard

Mine shows 84% and I haven’t touched the car since Saturday as I am out of town. I thought it would drop faster.

Why is that number 12v charge and not just the last HVB charge when Ford pinged your car for info?

FWIW, mine says 78%

My Mach is at 90%, Lightning at 78….

It only updates when the car is pinged or awake, so 84% was the last reported value. Not live. You could try pulling down to refresh on FordPass and then check the website again.

When I had the Chevy Bolt, the forum grey suits said that the car should remain plugged in all of the time, and that this kept the accessory battery properly conditioned, and I would notice the circulation system running occasionally to keep the drive battery conditioned.

So this is not true of the Ford, and there is no advantage staying plugged in when the car is at home?

For some reason this surprises me.

Keep the HV battery above a certain level, not sure if it’s 15%, and your HV battery will remain comditioned

thnx. Interesting! Mine’s 92% this morning.

…….though it’s now telling me I need a service which isn’t due until July 2025

Must be working on US service schedules instead of UK.

Messaging is not exactly accurate in most respects?

My Mach-E was 78%, refreshed and it dropped to 73%.
Lightning was 87% and dropped to 71%.

Mach-E was last driven Monday. Prior to refresh, app was updated 18 hours ago.

Lightning was last driven Thursday. Prior to refresh, I think app said the 17th. I looked for dates on my tablet after forgetting to do it before refreshing.

It would be nice if this isn't a mistake and it stays on the website.

Sounds good, it’s normal for it to drop by about 3% a day.

I get the dreaded 12V fault all the time too. Dealership has no clue why and says the battery is testing good.

And just today i got this new message that i had never seen before.

I have seen this as well. After my recent trip to the dealer to find my 12V battery is fine AND a software update for recall 23B50 it has settled down. No more warnings. I do plug it in every day now as well.

Turn the car on in your garage occasionally. It will shut off after 30 minutes and charge up the battery in that time.

Or you could get a battery maintainer.

Additionally I’d recommend disabling welcome lighting to reduce the battery drain.

This message is somewhat expected for a car that is barely driven, especially short trips.

Is this a giod maintainer cist $85.

Interesting, thanks Lee. Mine showed 86%, then 85% after a FordPass pull-down refresh. I then accidentally started to condition the cabin then turned that off. Checked again and it was down to 84%.

Last driven a little under two days ago, FWIW.

Overthinking spoils the enjoyment of these wonderful cars and attempting to manage something which is already managed is pointless.

For many of us, fiddling with things is probably our hobby.

Enjoy?

????????

I examine cars for a living so have no time or interest in fiddling for a hobby??
