Maybe. Rechargeable batteries, even the alkaline kind, tend to provide a
very steady current, and then drop off sharply when they are almost fully
discharged. Alkaline batteries have a steady but gradual decrease in
voltage. The curves look something like this:
rechargeable:
-----\
|
|
\
|
|
Alkaline:
\
\
\
\
\
\
The slopes are too steep, but that's life in ASCII :). Anyway, most
electronic devices that have power level sensors are calibrated to the
power curve of alkaline batteries. If you put something else in such a
device, it could fail without warning.
Also, rechargeable batteries are not good for high instantaneous loads.
Trying to deliver power under such requirements can cause physical damage
to the batteries.
