Cold weather battery capacity loss for lithium?

I think its pretty well known that lead batteries loose about half their capacity when they are cold (around freezing). Does anyone know what kind of capacity loss lithium batteries have when cold?

Well, I found my answer on another forum. I'm back posting here so the info is around for those who search.

Looks like you only loose ~8% capacity at -25C/-13F. Thats a lot better than I had thought!

Anyone know of a similar chart for a lead battery. It would be nice to compare.
