The batteries pictured have the same mAh rating as a Duracell alkaline 9v. You should expect roughly the same performance but the possibility of a rapid drop towards the end of the charge. I'd have more than one with me and plan to swap them out if it's a long show.

Current draw on these mics should be pretty low. Any reason he can't use one of the Powerex options? I know they don't have the capacity of the newer lithium batteries but I've never had one die.
