Does anyone know how the cold weather (below freezing) affects the batteries? I can keep the transmitter relatively warm, but what about the collar? It's snow season now, and last night it was -11 Celsius. I've noticed the collar shutting off lately with very limited use (ie. once in a two hour walk) but I don't charge it daily either. It didn't seem to need to before. I have it on my dog for hikes in the woods, so there's not much training going on, but I do want it ready just in case. Collar is a dogra 200

All batteries have a decreased ability to hold a charge in very cold weather. The batteries in an E collar have one significant advantage, they tend to be nestled in fur and directly next to a warm body during useage ( i.e., your dog <img src="/ubbthreads/images/graemlins/wink.gif" alt="" /> )
Cold sucks the life of most batteries. Lithium batteries will work down to -40 deg C/F but they are not rechargeable and may not be available in a size that fits that collar. Other than that keep it fully charged.
How long does a fully charged modern e-collar hold it's charge when it is cold? Temps of -10c on average. Say a Dogtra 1700? As well now that the colder weather is upon us do the batteries in this e-collar if it is always on the charger at night not completely drained would the battery start to get a memory or is there a way to fully discharge the battery before going on the charger?
Question 10 : How and when should I charge my Dogtra e-collar or RR?
Answer : Your Dogtra training collar has Ni-Mh batteries that can be charged at any time. There is no need to drain them down as you would with Nicad batteries, which have a memory. Please note that we do not recommend trickle charging (leaving on the charger nonstop when not in use). To attain a complete charge we suggest a 14-hour charge on both the receiver and transmitter.
Question 11 : How long will the batteries last on a full charge?
Answer : The batteries in the units have an average standby life of 34-hours.
With moderate nick, constant or pager use, battery life will decrease to approximately 20 hours.
If the unit will be stored unused for an extended period of time, we recommend fully charging the batteries every 2 months to maintain the batteries.
And on pg.12 of the manual, it says that in cold temps (10* F or less) the transmitter may be slow to respond or hard to read. It suggests carrying the remote close to your body to warm it. It doesn't say anything at all about the battery having a problem in cold temps, though I know my other equipment doesn't hold a charge as well in cold temps.

Hope this helps.
Yeah that helps I was more worried about the receiver than anything. Working outside up here for years you learnt to put your hand held radios etc under your parka if possible. Nothing like getting your vehicle stuck in a bush lot somewhere and having to hoof it out because your radio is dead because of the cold to teach you that lesson.
