Alright guys, I'm back with an update. As I mentioned earlier I am now starting with 4 new batteries. I ordered the Powermax unit recommended by BLF13. Due to some commitments and a camping trip for the fourth of July I just now have had the opportunity to disconnect the batteries and take readings. After 24 hours with no charge and no load the voltage reads 12.62 and the SG on all cells reads 12.60. If I understand my hydrometer correctly I am to add .0004 to that for temp adjustment. So now, how to properly proceed?
