Improving a "Used" Battery Can be Done
I got a used pair of Trojan T-1275s (150 AH each , 82lbs) that the previous owners (new and used golf car dealer) claimed were at about 86% as good as new before they put them on the pallet where they...

K, good to see you back! Not sure how the T-1275s act for that. They got to their existing "full" ok on the 1093. It is the 1093 being able to get them full (so easy!) that is the make or break for me.
In this case with the T-1275s I did not have a target SG to reach that I could not get to with the 1093 like those dratted 27DCs I had. So whatever they got to was ok.
Looking back, it seems the 27s were already on the down-hill slide and their SG was therefore lower at full than when new.(Now I know more about SG vs SOC on hard-used batts.)
Also I was unwilling to believe those 27s were not able to be charged to good as new when not that old. That would have meant my camping routine was not good for them! So maybe I was getting frustrated for nothing--not sure.
If I ignored Peukert, which I could with so many batts, then I should split the bank and put the inverters on the 12s and the rest of the rig on the 6s. But I only have one Trimetric, so I would lose my AH count. Also need two solars (which I had for a while there) You just can't win, boo hoo.
