Expected voltage sag?
I've got two 6 volt GC batteries. I have an inverter just powering a laptop. It's pulling under 100 watts AC. What kind of voltage sag would you expect that to put on these batteries if they were full...

My batteries got hammered pretty bad last season while the trailer was in the shop. Solar was disconnected and batteries were deeply discharged. I suspected they were shot but I've tried nursing them back with equalizations and being maintained with temperature corrected 14.8V charging profile. But I think they're damaged. After a full day charge, the inverter draw alone with the laptop charger will drop the voltage to 11.6V and hold steady. The voltage will often recover back to 12.5+V even after running this load for a while. Voltage reading is coming from the SCC voltage sense wires at the battery terminals.
