Hi, Steve
The BP-85 is a higher voltage (but lower capacity) battery that will run
the radio at 5 watts output. It's available from some of the after market
places like W&W www.ww-manufacturing.com. I tend to favor the 7.2 volt
batteries, as I get much longer life. Most radios put out a bit more power
(2.5 to 3 watts). The 1.5 watts seems a little low. Did you use an
accurate meter?
The BC-72 desktop charger should be a rapid charger, taking about an hour
and a half to fill up the BP84/BP85 batteries. It runs on 12 volts (from
your car, or a hefty wall-wart).
I don't have the 24AT, but I have some of its siblings - the 2SAT and
3SAT. Those radios run directly from 12 (13.8) volts on their little power
connector. You can NOT run them from the wall-wart chargers, but you can
run them from a regulated power supply that does 3 amps or so. You can run
them directly from your car, but you might run into alternator whine or
other noise, unless you use one of the filters. I'd expect the 24AT would
permit this as well.
