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.
