We have a huge system that includes a turbine producing more than 1000W continuously. Our battery bank of 16 Trojan T105s are kept at a float charge state 99.99% of the time. There is a 10A (53V) difference between our sources and our Load + Diversion output. I have checked our calibrations and conductivity between all the terminals and batteries. Is this loss typical (producing heat / H & O2,) or is this a symptom of some battery cells failing?

No once the battery is fully charged and the system cuts back to float mode, there be hardly any current flow. So if you are sure there is no load drawing any current, and you are seeing something significant, then you should closely look at the batteries. When was the last time you checked all the cells rested and took hydrometer reading? Equalized?
If I had to guess if there is a problem with the batteries you have one or mored with low cell voltages.MSEE, PE -
I equalized about a month ago (when I first noticed this), topped off with distilled H2O, took hydrometer readings (all 1280-1285) and checked terminal conductivity at this time. After finding no problems I asked the guys at Backwoods Solar (whom I bought some of my components from) and they said it must be normal.
But, it just doesn't seem right to me.
These batteries had several years of hard service, back in the bad ol' days of our generator power production.Comment
