Maybe other people have had different results but both my buddy and I have been running the same battery since we bought them, I called to ask him after we discussed it here. I'm not sure how much scanning and stuff he does, but I yse the crap out of the scan feature AND my Bluetooth is always on because 2 of my kids and my rifle use the BDX, so the signal is going back fourth quite a bit. Unless we have a handful of others saying they are having battery issues, I'd send that suckered in to get looked at. I've run 5 or 6 different sets of the sig bdx binos since they came out and I'm always scanning to see how far stuff is away, how close two ridges are from eachother etc, plus the sig scope connections and have never had one not last at least a whole year. What about others, what are you guys seeing??? Anyone else having battery issues?
