by coincidence or let's say I was curious, I opened the electrical info window. I don't understand the dynamic condition of the battery shown there. It seems to be illogic for me. The resistance is continously increasing and the capacity is continously decreasing. Temp is stable, as well as voltage current showed 0,4 A slowly decreasing until 0A. The generator is on main position, so the capacity should rather increase than decrease. Can somebody explain this?
 ok, I closed the window for some minutes and re-opened, now the capacity has changed from 630 W/Hr to 659W/Hr and the resistance is at -1.0 Ohms (was >2000 Ohm before). A negative internal battery resistance isn't common I guess ;-)
