Thanks Mate,
I have yet to try and do a full night with them of course,, but already I have a sneaking suspicion that I won't get anywhere near as long battery life (between charging) as I get out of my old binocs.
With as little as five minutes use just looking over the house paddock the battery indicator shows 1/8 used on the external battery.
Whereas with my old ones which only ran one single battery, it used to take an hour or more for it to show 1/8 discharge.
On an average nights use with the current hours of darkness I could start at 7-30 pm and get thru to just before dawn before full depletion,,,, and then swap over and insert the spare battery that I carried.
But at the seeming discharge rate of the new binocs,,,,,,,,, I'll have both the external and internal batteries fully discharged at approx 3AM
NOT HAPPY at this stage.
I'd rather have a bit less knick knacks, and more hrs use out of the batteries.
I do not fear death itself... Only its inopportune timing!
I've come to realize that,,,,, the two most loving, loyal, and trustworthy females in my entire life were both canines.
