[Elecraft] K2 - How low (in voltage) can it go?

I'm testing my K2 for portable operation by repeated transmit/receive cycles
on the batteries using digiatl modes (Oliva 8/500).

Of course, transmit takes more current and lowers the applied battery
voltage from the receive value.  Currently, the battery can have a voltage
in the low 11 volts on receive and go below 9 volts on transmit as the
battery is depleted.

What happens to the quality of the K2 output as the battery voltage
decreases?  Should I plan to stop sending at some battery level on transmit? 
(i'm getting output below 9 V). Or will the K2 simply stop sending when the
end is reached?


Thanks,

Chris
