Being the first winter I've had the echo battery saw, I took it out just to make a few cuts yesterday and the saw cut out and and triggered the battery safety shut off after just a few second. The saw and battery were in the cold garage (about 35) but even after taking a battery in to warm it up a bit, still same thing. is this normal for battery saws to not work in cold temps? Big negative on battery saw if thats the case.
