You might even get away with NiMh cells.

Hello - Depends how many you mean - remember we're talking 2 amps at
1.5v. NiMH are 2.8Ah. I tried them - they ran down almost immediately.
I think Cyclon 2v are the way to go.

Not if you go for D size NiMh or NiCd cells, NiMh can be up to 11Ah
for a single D cell. I did explicitly say C or D size cells.
