From the experience from the 8.4v at 150mah, the 9.6v @ 200 does not
give me
much extra time to work with. The 8.4 lasts 1.5 hours. I need a
minimum of
2.5 hours to allow for communion time. Granted, the 1.5 hours is on
"cooked" batteries and we will be getting a proper computer controlled
charger this time : ). Through basic, and admittedly incomplete,
calculations the 8.4v at 260mah *should* give me a much longer life than
the
9.6v at 200mah by almost a half an hour.

Your assumptions may not be valid. The performance differences will
depend on the design of the TX power supply, its LVD setpoint, and the
battery discharge curve. Buy one and try it...



I agree, my assumption may not be valid. That is why I admitted that my
calculation is incomplete and said "should" not will. There are a lot of
variables. I need to know what the "death voltage" of the battery is. The
"dead" batteries that can no longer power the mic do fine on my answering
machine. I am only using part of the capacity of the battery because of
power needs of the mic. etc. etc. etc. That is why I am trying to find
both increased voltage and increased mah. I may have to buy one of each and
check it out at home to determine the actual useful life and then buy 2 more
of the best option. So again, do you know of a source of 9.6v 250+mah nimh
batteries?
