We had no chargers in camp. I had to let it cool off over night, a then run it at low rpm (idle) a second time.
Since then I bought the smaller Optima charger.
It varies the charge rate depending on what it finds in the test it performs.
Not bad for the size and price.
The Solar does the same. I am looking for the chart that tells how the different batteries are charged. Interesting stuff. The intelligent chargers vary the rate.
