Another low battery issue...

[LouG]

Mine just did the dash reset BS associated with low battery. I've just had it on a tender last week as well.
A bit bloody annoying

Battery Tender!

If you don't get a battery tender your battery will be hurt especially after having it dead once before.

After the last update I started getting charging system needs attention once every time I dove. I always have a 5 amp tender on if the car is not going to be used for a time.
I know what my charge rate is while driving and didn't see any issue.
I then decided to do a battery reset and haven't had the message since.

We took delivery of our 26 GT vert on March 4. The Mustang is not a daily driver as we are retired. We went out of town for three weeks and come home to a dead battery, click, click ,click. We jumped it and drove it with no issues since. We are going out of town for six to eight weeks. Should we buy a battery tender or just jump it when we return? Or should we disconnect the negative And hope we don’t ruin the battery?

Either one, battery tender is the easiest thing to add. Modern cars always have a draw on the battery, those remotes, remote start, etc all draw power all the time. For the last 20 years, if I have a car that is going to sit more than two weeks, its on a battery tender.

My 2025 GT is my daily car, i drive to my work only 11 km round trip. Last winter the Start/Stop stopped working and it don't work any more ( he he he.....), only the no available icon on screen, no battery alerts message. When the GT is over 10 days stopped, it show the sleep mode but start perfect again. In the daily normal use the automatic software updates are OK. I dont use tenders and here the winter is soft.

I’n leaning toward disconnect the negative and then use a tender if desired. The battery management system (bms) may benefit from a reset when using a tender.

Edit: I’n = I’m

A trickle charger... or you will ruin the battery
