yabasoya Posted January 5, 2014 Share Posted January 5, 2014 Batteries: http://batteryuniversity.com/learn/article/discharging_at_high_and_low_temperatures Cold temperature increases the internal resistance and diminishes the capacity. Batteries that would provide 100 percent capacity at 27°C (80°F) will typically deliver only 50 percent at –18°C (0°F). The performance of all battery chemistries drops drastically at low temperatures. At –20°C (–4°F) most nickel-, lead- and lithium-based batteries stop functioning. Although NiCd can go down to –40°C (-40°F). Electronics: Well there is so much info on this but a Linksys router is designed for 32-104° F. On a side note, it hit 5°F the last couple of days and my gps fired right up in my car, although the display was a little slow to refresh. Just keep your radios at 1 watt and it should keep itself warm ;) Quote Link to comment Share on other sites More sharing options...
awskier08 Posted January 5, 2014 Author Share Posted January 5, 2014 Temps here in Minnesota are averaging about 0* though. Guess I'll stick to indoors for now. :) Quote Link to comment Share on other sites More sharing options...
barry99705 Posted January 5, 2014 Share Posted January 5, 2014 I used to keep photo lithium AAs in my mini-mag flashlight when I was a crew chief in Alaska. They were the only batteries that would continue to work during the winter. Quote Link to comment Share on other sites More sharing options...
