I've not seen the Quantum HT batteries, but I have had very positive
experiences with the Quantum batteries for camera flashes. As I
recall, they were high capacity gel cells with charging circuitry etc.
built in to prevent overcharging. (A photographer friend of mine
leaves hers plugged in all the time). Hope this helps.

..so break the rules ! (thats what they are there for!!!:-) ). Go buy yourself an unobtrosive (size wise) antenna, and put it up, if you get complaints, explain to them that it is for emergancy communications (or join RACES then there's no problem!). If they still insist.... then take it down and put it up inside.
Seriously, if you explain the emergancy communications aspect of the thing, most places will not object.

Kevin, I'm using a receiver that probably only has 20 mv sensitivity!
Here's my setup: I've taken an old FM broadcast band stereo receiver
and built into it a converter (actually a 50 MHz oscillator) so that
it now pulls in the local 2M repeaters. You can overcome the rotten
sensitivity with a good antenna. Oh, the selectivity is quite wide
but our repeaters are widely seperated on the band.
