Still pulsating dot. See video posted above.
Some interesting observations today.
The MRO after 88 days has a battery voltage of 1.98. Pretty slow drain on the battery compared to the T2 that is has been on for 6 days less but has less volts on the battery.
What's interesting is the MRO dot started flickering at 38 days (no voltage data available) and it's still flickering right now but a dot is still present. It's barely visible but still there.
To make sure it wasn't an isolated incident or failure of the MRO, I placed that same battery in 3 other MROs (brand new). All 3 have the same pulsating dot. I could try it out on the remaining 2 dozen + that I have but I think 4 is a decent sample size.
I took that same battery from the MRO and tried it in the Test Aimpoint T2 and the dot is perfectly crisp.
My conclusion is the MRO requires a higher voltage to run. Once it drops below a certain voltage the battery drain pretty much stops.
The Aimpoint seems to be able to run at a much lower voltage.
