Hmm.  This is not a case of "if a little is good, a little more is a 
little 
better." You might want to keep a close watch on those cells during the 
next 
charge.  

Did you follow your batteries' manual on proper charging right before 
watering?  I don't know about your BB-600s, but with Saft STM modules, 
you'd 
have electrolyte running out the vent hoses on the next charge if you 
didn't 
follow the correct procedure.  This is because nicads' electrolyte level 
rises quite a bit more on charging than does lead batteries'.  The 
watering 
cycle described in the manual is designed to bring the batteries to a 
specific state of charge and temperature, so that watering produces the 
correct electrolyte level in the cells.

And you overfilled them, too.  Definitely keep an eye on things.

Of course as I say above, this may not apply to the BB-600s, or may apply 
in 
a different manner.
