how to make 6 volt .5ah battery power supply?

Is it possible to built by 1.2 volt 2500mah NIMH batterty. or any other way?

go to radioshack and look for voltage regulators. I'm pretty sure if you describe what you need then they will have it.
if you put 10 in series you would have 5 ah and you could then bring the voltage down with a 6v liner regulator!!!

If you put five of those 1.2V batteries in series, you will have a 6V, 2.5Ah pack. (2500mAh=2.5Ah)
