Yes, I am unaware of any battery type that is not affected by cold temperatures. The chemical reaction is basically just slowed by colder temperature.

so let them warm up before use...or recharge?

Topping them off will also warm them up.

Around 30F I would just top them off and let them warm up themselves, any colder and you would probably want to warm them up before charging and/or using them. Assuming you have a safe method of doing this, of course.
