Unfortunately, I never got to pressing the "post" button yesterday and when I did now, it all disappeared
Here's the short version:
Your charger should not be used for that purpose. It will have a too high voltage for it. For a single time, they should survive without significant loss however. The only kind of chargers you should try recharging semi-discharged cells with, is quick charging smart-chargers with dU/dT charge termination (and slow, tapered-charge chargers with a rigid voltage control).
Memory Effect has never
been a problem in consumer grade nickel based battery cells and charge/discharge methods.
What you will be dealing with if you do it regularly is voltage depression and to some degree venting of the cells.
1000 recharges is a myth based on cells 100% controllable and correct environment and charge/discharge characteristics.
The only battery technology that can be safely topped up is Lithium.
