That is crazy! Where (and why) does Ford recommend disconnecting the 12v battery before trickle charging? I do not see anything in the owner's manual about that - only to disconnect before storage.

However, Ford recommends disconnecting the 12v battery if you are going to put a trickle charger on it. If you disconnect the 12v battery, you can't run the ProPower Onboard.
That is for storage "When not in regular use". I've trickle charged vehicles, Polaris Rangers and lawn tractors all without disconnecting the 12v.
