Sorry if this is a dumb question but here goes...
Are battery boxes specific to a brand of microphone?
For example, if I bought a set of mics as well as the battery box from one manufacturer, can that battery box be successfully used with the mics from another manufacturer?
Or do things like impedance matching or whatever need to be considered as well?

Adding a little more detail to what John said, battery boxes can provide different voltages and frequency responses. For example, the series resistors in our HEB battery box is different than the one for our Low Cost Binaurals, despite them both providing nominally the same voltage. Too low a resistor value and the HEB's DPA capsule is in dangerous territory.
And the battery box for our CS Binaurals is a drastically different voltage than the HEBs. The voltage is selected to optimize performance.
So to answer the original poster's question, battery boxes can differ not only by brand but also by model within a brand's product line.

PIP battery boxes are similar enough to be interchangeable. When you get into manufacturer-specific battery boxes, like AT's, that may no longer be true.
For example a PIP battery box cannot be used with Sonic Studios DSM mics, but they are designed to run on much less than 9 volts.
