I went on vacation and left my 2018 Jeep Wrangler home. I thought that I should connect a thickle charge to the battery to keep it charged up just in case, but I decided against it. After returning 10 days later, I came home to a completely dead battery. When I connected a trickle charge to the battery to slowly charge it up, a clicking noise from the engine started. The key was not even in the ignition. (1st video). I disconnected the trickle charge and connected a Diehard battery jumper to it, and the sound was different with the light flashing inside the Jeep. Again, the key was not in the ignition. (2nd video). I thought it might be the starter, but the ignition was never turned in order to activate the starter anyway. Has anyone ever experienced this? The battery is 4 years old, but showed no signs of weakness or drainage prior to leaving on vacation. Please Help!!!!!!
