    Don't know where to ask this so I guessed here would be best.
    My old Kestrel 4500nv screen blanked out on me for a while today. It was out in 35* temps for a few hours & when I turned it back on after it timed out (15min) the screen wouldn't come on. When I got home I turned it on & it worked fine and battery still said 100%. Batteries were replaced weeks ago with Energizer lithium.
    Think it was the batteries or is something else wrong?
    Thanks.
     
    I recently changed from alcaline to Lithium batteries and when I first turned it on I got the black screen. I messed around with it for a long time and still black screen. I was getting ready to send it in and fiddled with it some more and it started working. Mine is a 4500nv also. So far it has continued to work.
     
    This is the 2nd or 3rd set of lithium batteries I've used in it. It worked fine for 3 weeks of hunting on these batteries before yesterday. I've had other lithium batteries just die suddenly in the cold but they didn't show 100% after warming up.
