I have used my Argosy I (analog dial) on many a Field Day on 5W, and
easily operated the entire 24 hours on batteries. I typically use a
much bigger battery than needed, such as an Optima blue-top (55AH, I think).
From memory, the 590mA RX current drain is about what I measured
too. About half of that is the panel lamps, which I disconnected.
Being incandescent, they consume about 280mA of current. Once they
are disconnected, you get a very reasonable 250-300mA current drain on RX.

I have an old Argosy 525 (Analog). I measured the power consumption a long
while ago.
What I got was:
Receive: 590ma
Transmit low power: 2.2 amps , power into a 50 ohm dummy load was 4.5 watts
Transmit high power: 7.6 amps, power into a 50 ohm dummy load was about 40
watts
Power source was a 12.6 volt deep cycle lead acid battery.
All dial lights etc were as supplied with the radio.
I also used a fast acting circuit breaker between the battery and the rig.
Ten-tec said this was important!!
