Default Start/Stop, how long for Stop?

When in ECO mode, how long is the Stop phase supposed to last? I'm finding that, when stopped at long traffic lights, the engine will restart after only a couple of minutes. Is that correct behavior?
If not, might it show that the aux battery is low on "zots" and need to be replaced?

That sounds right to me. It cuts the engine and you'll notice that fan speed for the AC is turned down low. It will continue to blow cool air for a while but the heat exchanger quickly warms up and the inside of the car starts to get hot. It allows it a bit of warming but then the engine cuts back in to run the ac compressor and cool the car down. So it will be shorter on a very hot day
Try turning off the AC system/ fans etc. you will prob find it then sits off for much longer (but you will quickly get hot!)
