The factory supplied battery in my Transit250 only lived 2 years. The batteries Ford uses may be crap.
Also possibly relevant; there is an issue with phantom power drains on most newer vehicles, they supply circuitry that is always awake, always watching ( 😄 )
Many people who park their Transits that have older batteries when parked for more than 3-4 days find low batteries, and over a week or two it may be too dead to start. This is also likely to be the case in other Ford vehicles.
however, if you're driving your Maverick every day and you're getting this much power drain, something is amiss. Using a multimeter, you can check each fuse to discover what's still draining power when the truck is shut off (the cab light circuit may be activated if you have the doors open). Once you have a list of suspects, you can compare to the fuse map and see what is supposed to be running and what is not, and then trace down the actual issue.
Some things I've heard of causing this:
Auto door locks not triggering the sensor so the mechanism keeps "on" trying to lock the door (needs mechanical adjustment to allow lock to fully engage)
Trailer hitch wiring
Cab lights or radio staying on
Infotainment system is set to search for WiFi, and is constantly searching when there isn't any (like a phone does unless you turn off WiFi)
Anyone have anything else to add to this list?
