Sky works fine down to 2.2 volts in
- my above zero temperature
- With the Australian frequency
- With Alkaline batteries
- Non power save mode
I wonder why the voltage sometimes dips for a couple of minutes? I wonder if there is a larger than usual current draw from the battery?
If a lithium battery is near its cliff and then a larger current is drawn it might cause a steeper cliff.
My voltage graph did show a drop for an unknown reason then recovered here:
If that voltage drop is actually a real momentary very high current draw that would cause a steep cliff?
I dont expect it was actually a short because I would have expected a more gradual rise to its normal voltage. But perhaps the ‘short’ was very short at only the moment the voltage reading was being taken which then gave 59 seconds for it to recover?
I realise this is unlikely, but when I brainstorm it is important to offer all ‘thoughts’ to help inspire the solution.
