i put in a regular 9v, and it booted, but it would not shoot, the light wouldn't even flash, turned it off, put in 9.6v battery it came with, worked fine. but i need to still recharge it...lol.
I'm sure there is someone who's owned more, but of the 9 Tribals I've owned "ALL" of them were able to operate on a standard 9V alkiline battery. However, I will admit that I've only had one where all the little lights worked.
