The problem is on the right side, the left side (input) gives a different error message that relates to "input voltage"

ps it is not a good idea to charge AA batts at 3.6 amps. A 1 amp max rate would be more realistic so they do not get hot.

GULIO- i am only charging at 1 amp, we even brought it down to .7 amps.
SPARX- you could be right, i have a Dynamite(dyn4055) 12 volt 10 ampDC power supplywith input overload protection(internal-3amp)
SCOTTY555- Its 12volt 10 amper

let's start from the top then.

When you try to charge 8 series cells at 1 amp and push start what is the starting voltage? and then how long does it charge? and on the error message "voltage output is greater than ...." what is that figure?

If it is 20 then there is a connection/leads/cell/holder problem because that is the max voltage of the Ice's output, but 8 cells should never be over 15 volts.

What I said is correct. You could charge at 3.6 amps given the capacity of the batteries. But charging at max rate would shorten the life of the battery. The 1C rate is prefered to peak charge the batteries. At 1 Amp charging 2400 cells would take over 2.5 hours. For more info on batteries check out Red Schoalfield Battery Clinic. This guy has forgotten more than we know about batteries.

I suppose we can charge AA at nearly any rate from c/50 to 4C. Usually the skinny batteries with low discharge capability should be charged at less than .5 amps for long life. High discharge batts like subC (fat batts) can be charged at 3S or so. Many are chargeing AA at 8 amps with cooling. I'm more trying to focus on getting the op's problem sorted out with the ice charger.

The ICE has a difficult time charging/reading AA batteries, much harder to read than the sub-c or even 2/3A. My Ice will peak out on my transmitter packs, and and then I will put another 1500 ma into my transmitter with my integy.
