Sure. The perfect way.
If you are familiar with electronics you also could test the bat by probing
for voltage and temporarily attaching a 1R2..1R5 (>0.5W! better a 2W) during
watching the voltage. (<0.5sec). Or use a incandescent lightbulb that's
drawing ~2A @ 3V5, instead of the resistor. You probably need a fast DVM or
an analog voltmeter or 'scope for this.
Bat voltage must not drop below say 3V.
Well testing with a spare bat for sure is much simpler and yields more
reliable results anyway.
