Bruce;

Thanks for that. I've been wondering about the water loss in these cells as 
well. I personally removed them from the generator room where all 20 were 
installed on a rack securely bolted into one series string by nickle plated 
cell interconnects. The thick layer of greasy dirt on the tops of the cells 
and interconnects did not indicate that they had been moved for a long time.

My guess is that the battery pack was ignored for an extended period and 
gassing of the cells under continuous charging caused the low electrolyte 
condition. Most likely the generator service company in town took one look 
at the battery after it failed to start the generator and simply installed 
the two 8D batteries that it uses for cranking today. The question is why 
only six cells were low while the other 14 were within the min/max 
indicators?? There was no pattern to the placement of the low cells 
(six-in-a-row, ends of the pack, etc)

I'm moving forward empirically by topping up the low cells, charging, and 
will do a load and capacity test to determine if these cells have been damaged.
