I just topped my battery off again overnight. Started at ~1.7amps, then after a few minutes, I heard the fan on the charger going, and it was putting in 3.5amps.
This morning, it was reading FUL. You can guess what that means. Like I said, I had the same problem, and charging it up every 4 or 5 months keeps it topped off and gives me peace of mind to run seat heaters, defoggers and to use the rest mode when the car isn't running.
Rudeman. Awesome tip. I had the same issues with increase battery discharge and low battery levels. I picked up the exact Motomaster unit you specified for 1/2 price, plugged it in, and voila, all my errors disappeared! Thanks so much!
