Adding to Bill,
You need to find out what caused the LBCO? A battery summary screen will "show" when this happened in the 24 hour day? It may have nothing to do with the battery and may be load related? Since they are 7 years old, they may have good SG but very little capacity left!

I see variations like this all the time. Are you using a refractometer or hydrometer, are all the cells same manufacture date, are some cells warmer than others, terminal connections all clean? I've tried "correcting" this from happening many times to no avail or marginal help despite longer absorb times or EQ-ing. Some of the packs I maintain have different manufacture dates within the pack which I've assumed may have an affect.

The bank is probably 7 years old and this is not a full time residence. It's shutting down with LBCO error. I need to go check the site, but I'd expect a dead or weak cell here. What else can be checked , battery wise? Jeremy Rodriguez Solar Installation / Design Expert All Solar, Inc. 1453 M St Penrose Colorado 81240 Sent by Jeremy's iPhone.
