Ok, what I have here is a project using the guts from an ht1000. The unit is housed in a water tight box and is basically a personnel sensor coupled to a radio to send the info. (for law enforcement purposes)
I have been using an old bag phone battery 2.2 amp 12 volts and it works fine. I am wondering if there would be any advantage to using a series of D cells to = 12 volts. How long do you guys think an ht1000 would run on a 2.2 amp gell cell as opposed to 8 good D cells. The voltage has been compensated to match the radio requrements in the unit. I just don't have time to do an in field test of both battery systems.
Any ideas, which should I use?

The last time I tested the 7.5 v.
1100 ma battery. I found 60 ma. with radio turned on, 160 ma when radio was hearing a call, and 1600ma when txing .The battery is
called 5%/5%/ 90% for 8 hours.
1/2 hour tx 1/2 hour rx and 7 hour turned on.We did this test for search and rescue.
We use 2200 ma batteries now lasts 2 times longer.

Turn on the battery saver feature in the RSS.
Also use a regulator off the 12 volt battery to get the voltage down to 7.5 volts for the radio.
Use six or seven D batteries for 7.5 volts.
For what you are doing, try setting the transmitter power down a litle and use a six volt gel cell, half the volts--twice the current in the same size battery. I have not tested a HT1000 on six volts so it mite not work, low battery alarm, ect;.
