Is there away to Test the Health of the battery(s)?  2016 Ford C-Max; 5,500 Miles Purchase date 4/9/16   I am having concerns that the Batteries (Vehicle is NOT Plugin model....sure there is a better name)....seems battery is taking longer to charge and runs down more quickly.  I have actually been purposely driving it hard (keeping it out of EV) to get battery per symbol to get into the 80% range....but as I wrote, driving it normally to where EV is in use, Charge seem more quickly to get down
