So had the cranking battery on charge yesterday. Took it off and about three hours measured the voltage across the terminals. Read 12.68 volts at about 6pm. This afternoon at 4pm measured the voltage at 12.62 volts. Had disconnected the auxiliary battery yesterday. Went to start the D3 wouldn’t even turn over. Measured voltage at 11.2 volts. Any hope for the battery?
Unfortunately no.
Once a battery starts behaving like that, it's stuffed.
This would also most likely be the reason your Optima was not holding it's voltage, but it is probably good.
