My two year old Interstate battery in my 2011Edge has twice been drained dead in the past month. I've had the battery tested twice. Once by Interstate and once by CarX as well as the starter and alternator. All come back good working order. Only thought now is something electrical is slowly draining my battery over time. Ever heard of this or any suggestions?

 

Very common problem these days!
You have a choice to either chase the drain down with voltage drop testing or have a competent shop find the cause of the drain. Newer vehicles have several modules that are supposed to "Go into sleep mode" once the ign is turned off or soon thereafter, to prevent the battery drain problem. There is a good possibility something is preventing that or a component is not shutting down as required. A good scan tool will help to locate the problem area, but most folks don't have one and shops charge for diagnostic time to determine the cause. A second opinion never hurts.
