Charging with a charger in garage

[QuickRick]

Guys and Girls, We have a 2025 ST that we bought to leave in our Florida home garage. I’m getting a message off of FordPass that says “ battery saving mode” despite having a maintainer/ charger attached and **working. In fairness I can’t see the connection as we are 900 miles away. On the F150(we have one) Forum I was told that it matters which side of the cable you apply the charger. Do you think that this means the vehicle does not see that charger? Kindly chime in! QuickRick ** at least I believe

I put a 1amp maintainer on about once a week. I’ve noticed FordPass doesn’t recognize the battery becoming fully charged until I next start the vehicle.

Only explanation is that the battery maintainer is not attached or is not working. There should be no reason why you should get that message with a working battery trickle charger.

I believe if the vehicle is not started over a certain period of time, the vehicle automatically goes into a deep sleep mode (AKA battery saving mode). I do believe this is regardless of having a maintainer on it or not.

YES SIR U must put Negative charging lead(clamp) before BMS sensor. Not directly to Negative battery terminal , or ur right , computer is not even seeing tender/trickle charger ! There are a few good vids on YouTube about this exact scenario. Best of Luck
