Sig Sauer BDX warning.

[Fred B.]

Just wanted to let you guys know before spending money on this system, beware IT IS NOT FOR WINTER HUNTING.
I found it the hard way after a wasted hunt.
The batteries in rangefinder and scope will not function in sub freezing temperatures.
Sig just confirmed it and I did tell them they need to mention that in specs.
If I knew it, I would have not bought it or make sure to take hand warmers for scope and keep the rangefinder in my pocket.

Batteries aren't exactly known for being reliable in cold weather, that isn't Sig's fault.

No, it's not Sig's fault, but it is a good reason to choose a scope whose reticle will function for you with or without illumination - choose one where illumination is a useful bonus, not a necessity.

I don't run batteries in optics , just because of that... They will run forever , till you actually need them.... Sell it and pick up a plain old normal scope... Sorry your hunt got ruined , that sucks for sure...

That's not good news as I have two Sig rangefinders. Batts don't do well in the cold but on the other hand I keep all my small batts in frig until I need them ,they keep better than on the shelf for some reason? Was told that years ago and have been doing it ever since

"On storage, batteries have one enemy, and that is self discharge, which slowly takes away a battery’s charge. Self discharge is lowest when cold, worst when hot. So cool storage is good for a battery. Self discharge is a chemical reaction; reactions are retarded by cold.

On giving up power, that is also a chemical reaction. Heat always accelerates and improves chemical reactions. So batteries will give up the most charge capacity when warmed and give up less charge capacity when they are cold. So warm up batteries when in use to squeeze every last bit of power from them."

"Alkaline batteries stored at "room temperature" self discharge at a rate of less than two percent per year. So normally refrigerating or freezing them will only help maintain their charge by a tiny amount. Hardly worth the effort of chilling them. However, if alkaline batteries are stored at higher temperatures they will start to lose capacity much quicker. At 85 degrees F they only lose about 5% per year, but at 100 degrees they lose 25% per year. So if you live in a very hot climate or are storing your batteries in a very hot location, it may be worthwhile for you to store your alkaline batteries in a refrigerator instead.

NiMH and NiCd batteries self discharge at a MUCH faster rate than alkaline batteries. In fact, at "room temperature" (about 70 degrees F) NiMH and NiCD batteries will self discharge a few percent PER DAY. Storing them at lower temperatures will slow their self discharge rate dramatically. NiMH batteries stored at freezing will retain over 90% of their charge for full month. So it might make sense to store them in a freezer. If you do, it's best to bring them back to room temperature before using them. Even if you don't freeze your NiMH batteries after charging them, you should store them in a cool place to minimize their self discharge."

Wow what great information, I no if they are in truck or equipment during warmer months they don't last nearly like being in frig

 

[Fred B.]

How about using a little bit of that battery to keep itself just above freezing? Or is that crazy idea?

My Sig 2k will not function below 6 degrees F, battery is fine, problem is the laser diode. If I keep the unit inside clothing and range quickly it works properly.
