I have two 6 volt batteries I charged and the readout in camper said 13.7
I ran my furnace in driveway for about 1/2 hour and when I looked at readout it said 10.0 with red light blinking.
Do I just need to get two new batteries before my hunting trip?
I did charge the batteries by plugging it in a few weeks ago.
