about USB Remote Battery

Hi everyone:
I'm working on my usb remote for A 590 but I have a question:
How do you get a voltage between 3.7V and 4.5V with a battery?.
Actually I don't know if 3,7 and 4,5V are the minimum values...In that case...what are the maximum ones?
Anybody knows if you can use one of 6V without problems?
Thanks!!!

A normal (computer) USB connection provides 5 volts across the power pins, so that is definitely safe. 4 rechargeable AAA or AA cells will give you that (the 4-cell packs that R/C people use in their models typically deliver 4.8-5.0 volts).

I used 2 x 3v button cells and a voltage regulator.
