A battery that has been sitting in a discharged state could well take 100 hours to fully recharge. Charge it at a slow rate keeping the voltage about 13.5. Charging at too high a rate will only cause the battery to get hat and boil out water. When fully charged, after removing the surface charge the voltage should be 12.6.
If after a day or so the voltage is at 10.5 you have a shorted cell. If the cell is shorted because of build up of material on the bottom of the case they can sometimes be restored by flushing out the debris. If the short is caused by a buckled or broken plate there is not much you can do about it unless you cut the battery apart to do a physical repair.
When I worked at an IH dealership we had several cases where kids had played in the tractors or combines and left all the lights on. They might sit that way for a month so the batteries were completely discharged. IH policy was to recharge them at a slow rate for at least 100 hours before testing them. Some would fail the load test even then but after sitting on the shelf foe 30 days they would pass. I used one of those "failed" batteries in my tractor for almost 10 years before I had to replace it.
