the batteries I have i float at 13.5v. once I disconnect them from the charger; I am guessing they shouldn't stay at 13.5v but drop down into the 12v range? example I had the batteries floating at 13.5 volts for a couple of hours. then is disconnected the charger and took a reading of 12.96v across the 8 battery string. this morning the reading was 12.84v. my question is; it this normal? you responded it depends on the make up of the battery. is there any other information I could get from the battery label to help?
It can take a couple of days for the top charge excessive voltage to dissapate.
Come back in a couple of days and tell us what you got, with nothing attached to them. If you are at or over 12.73V, then you are doing good.
What you are seeing sounds normal to me.
