Greetings

I am in the process of putting together (battery power supply) for my
amateur radio equipment....I have an ic 735 and ic 275a.

I have a number of rechargable nicad batteries 4.400 amp hour and 7.0 amp
hour.. 1.25 volts..

I need some information about the ic equipment which I can't seem to find in
the manual...
In the manual the d.c. input reads 12 volts...

Can someone tell me what the safe upper limit of these radios tend to be?

I don't plan to come anywhere need the upper limit but I would perfer to
make a battery pack containing 12 x 1.25 volt cells rather than 11 cells.

My battery analyzer, cadex 7000, can only analyzer a series string of 1 to
12 cells.
