Ooh this is interesting. I have had a flexTT5 go down like this twice when it has been cold and each time I have switched to another, I suspected it was temp related but have not tested it yet - it was nowhere near 0 degrees either. I was trying to trigger an acuteB2 AirS/R (inbuilt PW). Batteries are half finished alkalines.
Lithium AAs won't outlast alkaline, with equivalent power of 2900mAh but with a flat discharge curve. Operating range is down to -40degF and shelf life is 10+ years. They're significantly better at low temperature; at -5degF their service life only is decreased by 20% and output decreases slowly as the temperature drops. They're also much more expensive.
Alkaline. The Energizer has 2850mAh and the new Energizer e2 has about 15% more, or 3135mAh, and both have a sloping discharge curve. Operating range is down to 0degF and shelf life is 10+ years. They're not much better at low temperature; at -5degF their service life is decreased by 60% and output drops quickly as the temperature drops below room temperature. Although they're more expensive, they're comparable to carbon-zinc in terms of cost per hour of use.
