I've added a battery level check / fill to my maintenance schedule, once every 3600 miles.
If anyone needs the maintenance schedule, it's Yager GT 200i specific, and exceeds the recommended manufacturer maintenance schedule, with specific entries for engine break-in (more frequent oil and filter changes when new). Just message me if you want it, I've got it in Microsoft Excel .XLS spreadsheet and OpenOffice Calc . ODS spreadsheet format.
