AeroPod, PowerPod and Newton

Hi,
I have a PPv3 which when connecting to my Garmin today resulted in that Garmin displayed "Your power unit is critical low on power". After riding about ½ hour PP started slowly blinking red. After my ride finished which was 1½ hours after the red blinking started there was still coming power data from PP. So my question is: What is the remaining running time for PP when it starts blinking red?

Truthfully, we have not measured it...

When the light blinks red you have about 25% power remaining. That should be good for about 3 hours ride time, though we have not verified this.
