Okay. . .the batteries are two 12's in parallel.
My gosh, they are heavy. . .about 60 pounds each.
Label on battery says they are Deep Cycle RV/Marine - Interstate Batteries
30-month pro-rated.
They've been charging for two days. . .the camper meter said 13.1 volt this morning.
They started charging at 13.4 volts two days ago.
I took both batteries out and separated them.
No wait time.
Checked voltage - both batteries had an identical 13.02 volt reading.
Checked specific gravity in each cell with a cheapie battery hydrometer.
Cell readings are between 50-percent and 75-percent.
It appears the batteries are nearing the end of their useful life from my point of view.
