You can read it here: 27134433Coach Batteries in Motor HomeYesterday, lost shore power in campground (everyone).. My coach lights went out almost immediately. checked coach batteries. both batteries out of water. Filled with water. Within two hours of shore power bbeing restored, I turned off shore power to see if batteries had been recharged and lights worked, voltage was 13.1 and wall mount display said batteries were top condition. This morning heard what sounded like boiling condition in one of the batteries. Opened caps on top of batterey and could see water/acid moving and could smell the "rotten egg" smell. Went to Auto Zone, bought hydrometer, battery acid levels fine. Took some of the acid out of one cell that I think I had overfilled and put some water in another cell that I couldn't see any water in. left the cell caps loose, reconnected shore power and batteries seem to be working fine, no boiling and voltage check is good even when I turn the shore power off at breaker switch outside. Three hours later; batteries in great condition according to gauges. Question: Did I somehow fix the issues since everything seems to be working okay and there's no more boiling OR is there something going on that I should check and/or replace? Thanks in advance for anyone's help.
