The battery might need warmup, but it would have to be significantly below freezing outside to affect it. Electrolytic capacitors can freeze up but again, you'd need a Yakutia-like environment for it to actually pose a concern. Lastly I've heard of circuit boards warping from going from really cold to really hot, but those were power components.
