As Henry already posted, nope.  The voltage is more dependent on other
factors, so it's not a reliable charge indicator in itself.  However,
batteries as they reach full charge heat significantly and as a result
change their terminal voltage rather quickly.  Detecting that rather
sudden (relatively) change is how many chargers turn off (or turn to
"trickle").  If you could monitor pressure in the cell, I believe that
an increase in pressure would also be a good indicator of full charge...
