I decided to purchase a battery tender to keep the battery charged in the future, but now I can not get the car to jump start when hooking it up to another vehicle (2010 Mazda 3 and 2008 VW R32). The car just won't turn over and the driver side window will not respond at all. I have attempted jumping the car back to back days and no luck. Any thoughts? Is there some safety override that maybe I am missing...?
