Regarding the length of time to disconnect, Yes, I would agree it should not take four days. Using your numbers, 1 amp for 96 hours is 96 amp-hours. I bought a Marine deep cycle battery this spring that is rated at 105 amp-hours. After a discharge of 96 amp-hours this battery would be in the mid to high 10 volt range - two batterys of similar size would be no where near 12.6 volts. If 12.6 volts represents a 5% discharge, then your total battery capacity would need to be in the range of 1920 amp-hours to maintain this voltage after a 96 amp-hour discharge. 1920 amp-hours would be 18, 105 amp-hour batterys.

You are running two batterys and after a 96 amp-hour discharge the voltage is 12.72 - can something be connected and is charging the batterys....?

Today's Featured Article - New Life for an Old Allis - by Tyler Woods. My friend Jon, has an old '39 Allis Chalmers B. He thought it a marginal tractor that had long since served its time. She smoked terribly and never had much power but he couldn't afford another so he was limping along with what he had. Jon's Allis has a small front loader and though it doesn't carry much, it serves his needs. It was the hard starting and low power that made him think it was time to replace the old girl. Jon called me to help him discover why his tractor wouldn't start ... [Read Article]
