Been happening over the past few weeks.
The truck has a completely dead battery in the morning.
I'll jump it, drive it, and it's fine for the day. It's not even an everyday issue. Just Happens. Both batteries show the green dots.
I d notice that when I start the truck, the cluster shows 1/2 battery, then after about 30 seconds, the truck makes a small noise and the battery reads full on the cluster.

Those dots mean nothing. I would have them load tested. I will bet that at least one of them doesn't test good. What year truck and are these the original batteries? If you do have to change one of the batteries, change the other too. You need to change them as a pair.
