I need to purchase a power supply to cycle batteries at various charge and discharge currents, but without buying a single-purpose device.

All you do is set the unit to source voltage.
The key is to source the voltage that is lower than the device voltage.
And now set the current limit to what you want as the sink current.
Drain a 1.5V battery at a 100mA rate,
Set the unit to source 1V and a current compliance of 100mA.
That should do it.
From the 2303 manual, page 42
"During sink operation, the power supply does not regulate current. It acts only as a constant voltage load, not as a constant current load."
Do you know of any other 2300, 2400, or 2600 models that do not regulate the sinked current?
