Yep, I've discharged both batteries before charging (was quite fast as both came pretty empty, less than a minute of discharging in both cases).
In the case of the 9.6V battery, the voltage reading when the fast charging stopped was 13.5 volts.
*Edit* The cut-off voltage for the 12.0V battery was 16.9V. *Edit*

The charging recommendations written on the cells are 3A for normal charging, 6A for fast charging.
