Enviro Indoor (Pico W Aboard) - battery power

I have my Enviro Indoor working (feeding mqtt to Node-RED) USB powered, with the as-supplied firmware. When running off the supplied battery pack:

  • the red warning LED comes on for many seconds

  • the white activity LED stay lit in a steady pulsating fashion. I cannot see how this is good for the battery life!

  • I’m still checking the accuracy.

Are the LEDs behaving as expected, are they telling me anything?
