that would depend how they're charged but most will do 8.4V.  8.2V a little less common.  the nominal voltage is 7.4V and they'll spend most of their life around this range, before quickly dropping to 6V and then being shut-off by internal protection circuitry.

^ That sounds right. The Taobao page refers to 8 volts output. From experience with the Stepdance, when they die it is immediate - power light off, sound gone. There is no gradual deterioration of sound quality, at least none that I notice.

Thanks Justin,
 
would these be a good choice? or better to go with Ni-MH that may get closer to that 9v as a nominal voltage? Looks like I can by a couple of good quality batteries and charger for $50-$70 or I can just by alk one use for $6ea at the supermarket....Rechargeable seems like a much better option.

a few tenths of a volt doesn't make much difference
 
don't know where you live, but $6 each is a lot for an alkaline 9v.  i am buying them in bulk, and paying 90 cents each.  If I got in somewhere as a dealer/OEM it would probably be less.

Agreed, $6 is a lot for a 9v. You can easily get some from Amazon.com for about $1-2 each in packs of 1-2, or even cheaper if you get a larger pack.
 
That being said Justin, is the Pico Power tolerant of 9.6v? I'm probably going to go with a rechargeable set and I'm trying to decide between the 8.4v and 9.6v's (assuming they actually reach their rated voltages...)

I have already bought these rechargeable made by Maha Energy. Hopefully they will work fine with Pico Power.

Those are the same ones I've been looking at buying. I have that same charger somewhere, but I can't seem to find it. If Justin confirms 9.6 is fine I'll probably buy the same setup you have right there :p

I have the same charger. My batteries are by Powerex. Had it for my SR71A before. It should work. For the US, I get my batteries at Thomas Distributing. Good company.
