My 2015 Ram is on it's original set of batteries....a couple of times after running the grid heater on cold mornings the last week or two I've had a click before I turn the key back off and then it has fired up on the second try....Am I at the point I need to replace the batteries?
Maybe so. Had to replace batteries in my '14 last year. I had similar odd behavior on cold starts when using the grid heater. After testing the batteries I found one of them had a dead cell so I was essentially working off one battery.
Be careful when disconnecting. There is a fuse built into the positive battery cable post connector and mine popped somehow during the change. Those post connectors are a dealer only item.
