I did some experiments with the old batteries and the BD1093. Actually, I only used one battery to speed things up.
First, I charged until FULL with the BD, then turned on some lights and timed how fast the voltage dropped. In four and a half hours, 40W of lights dropped the voltage to 11.77 loaded, 12.09 with only the CO detector.
Now, recharge and Desulfate, and time it again. No change.
Now recharge and Equalize and time it again. Still no change. I really hadn't expected equalize to do much, since the hygrometer had not shown big differences between the cells.
Now, starting at 12.1 volts open circuit, I plugged in the WFCO and left it on for 12 hours, and tried again. This time the voltage dropped slightly more slowly than the previous checks. After the first half hour, the WFCO run read 12.55, while the equalize run had been 12.36. After 2.5 hours, the WFCO run was 12.1, the others just over 12.0 So apparently the WFCO after 12 hours did have it as well charged as the BD after FULL.

Hello all. I am very glad to have read this topic as I need to change my batteries right away. I had planned on going back with two more Optima's,

You have the 1093 so let's see if it can still do any good. Charge the batts to where it says FUL and then immediately switch to the 4amp setting and poke the hole to do an Equalize. Let that run till it says FUL again. Now reset and run another Equalize till it says FUL again. What is the SG now? (never mind the Recondition mode--it is dubious, iffy, etc)
Yes you have not been charging them to 100% often enough. You have to run an Equalize (or two in a row even) with the 1093 as soon as possible after every session off grid.
After that between trips leave the batts on the converter for their Float. Do not disconnect and let them sit for long periods. Water under the bridge now, let's see if anything can be saved as above.
When you do get your 6s, follow this routine--your 1093 can do it perfectly. I use the Equalize on mine after every recharge to FUL (which isn't full it is about 97% in fact) to get them from 97 to 100.

When I store the trailer during the summer, I just open the battery disconnect switch and leave it. During winter, I do the same, but I check the voltage occasionally and plug in overnight if it seems low. Generally, it doesn't seem to need that more than once or twice per winter.
There have been a couple of times when dry camping when it probably went without a charge above 90% for a couple of weeks.
