why is my battery dying over night if i leave key int he ignition
I have a 2013 f150 4x4 with 34,000 miles. I have installed 3 batteries in this truck. the first shortly after purchased. I would park the truck at night and it would not start the next morning carried it to dealership they replaced the battery and told me it had a dead cell due to sitting on the lot.(bought that story) not long after started having same problem had to jump truck every day. tried to figure this out myself battery got so bad it would need to be jumped every time I turned it off. replaced battery with a aftermarket still having problems carried the truck to dealership and they told me that this is normal if I leave the key in the ignition (not buying this story). has anyone else experienced the same problem. IS THERE A FIX????
