I own a 2021 gt and it is in winter storage . I have the ford pass app and I am getting the occasional message that the car is in sleep mode . I try to get to my car and start it . So far the car has started every time. I hope it keeps working
I didn't even get the message the second time. Woke up early on a Sunday, wanted to go to Cars and Coffee and nothing... no power.

I just invested in this: Ctek sense

My AGM was showing 65% charge after 3 weeks of cold and non use. Started just fine, but gave me pause. I pulled it and charged it with THIS charger.
Sitting at 96% charge now. No drop in 5 days of bitter cold.

Other than charging or replacing the battery is there anything else that would need to be done?

If its the factory battery, it is a POS.
Really ? Mines 5 years old. I can leave it for a month and it'll start just fine. Guess luck of the draw.

I have a Ctek wall-mounted between my Mustang and my Edge with taps mounted on each battery. I switch between cars so both batteries are always at 100% charge,
