Best Cold Weather Battery
(OP)
I am a development engineer for a company called Powertach. Powertach is an auto accessory that requires a wireless transmitter to ride on an automotive driveshaft. The transmitter is powered by three AA alkaline batteries. When I went to test the product yesterday morning I found that it did not transmit early in the morning. Once the car warmed up it began working and I read online that these batteries will only work at room temperature.
I wonder if there is a type of AA cell that will work in cold weather conditions so that I don't have to wait for the car to warm up. Thanks in advance for your help.

I don't want to power up my transmitter with these new batteries only to find that they will burn up my circuit.
Thanks for the help.
RE: Best Cold Weather Battery
How is a battery of the correct voltage going "burn up" your circuitry? Is there some violation of Ohm's Law here?
Did you read the datasheet, http://data.energizer.com/PDFs/l91.pdf, at all?
These batteries can only discharge about 2 amps, which is 1/5 of what a fresh alkaline battery can put out.
