[Harp-L] 9 volt rechargable batteries

[R Kraft <hoosierdads@xxxxxxxxxxxxx>]

Quick question for you heavy gigging folks.
Anybody use 9V rechargables for their wireless or pedals (or active pickups)?

I know they don't put out the full 9 volts and wondered whether anyone has experience using them.
I use AA rechargables for all AA batteries in my rig and it saves cash (and hassle, as they last at least 3X as long as alkalines).

Any inputs appreciated.
