FYI, it is a 12 volt, 200ma supply, 9 volt is a little low, if you operate
the scanner at the same time you are attempting to charge the battery.

Thanks. I hadn't known that. I haven't noticed any problems along
those lines, but since I've never tried using the correct adapter, I
have no way of knowing how much better the performance would be with
the right part in place.

I assume (yeah, dangerous) that there is an internal regulator in the
SC180B to drop the wall wart's output voltage to the correct voltage
for charging the cells in the battery pack. Whether Vcc for the
scanner is that lower, regulated voltage, I have no way of knowing.
Anybody have an online schematic for that scanner?

BTW, I like the SC180B a lot. I think it's my favorite handheld. I'm
kind of surprised I feel that way, as I been wary of the idea of
Uniden's proprietary battery pack. I have learned that they are easily
disassembled for replacing bad individual cells as they fail, so it's
not the issue I had thought it woud be. I have made a few spare
battery packs by now. The plugs are commonly found in cordless phones,
as are spare cells. I have a whole bunch of cordless phones that I
have liberated from the trash piles.
