I have also needed to top up the battery charge on mine since I have stopped working and don't drive the vehicle anywhere near as much as I used to. Must admit though that I have never got any message on the dash telling me that I needed to start engine to charge the battery - I simply notice the longer / slower cranking, especially in cold weather, and put the vehicle on the charger about once every couple of months for 24 hours or so.
I have three batteries in mine - the OEM cranking battery, plus an Optima yellow top under the bonnet and an Engel battery pack in the rear which runs the fridge - both auxiliary batteries are connected through a Traxide system.
I re-located the rear anderson plug to outside the bumper, mounted in a housing with a spring loaded cover (saves me having to remove the panel in the rear bumper to access the plug when I am charging batteries / powering LED camping lights or compressor etc). I simply plug my CTek battery charger into the anderson plug - it charges all three batteries in the vehicle, usually in less than 24 hours.
