The test current would be limited to 20mA, which might be a bit of a light load, but it could work.
20mA? It should not have to be more than 500 micro-amps. The AVR specs show sample rates of 1,000 samples/sec from input impedance of 10 million ohms. That's sample a current of just under one micro-amp at 5V.

I was thinking more from a standpoint of testing the battery with a load that approximates whatever it is intended to power.
