Note: block, not battery.
Most batteries do lose performance in low temperatures, to some extent. I don't know how this affects battery-electric vehicles, but it seems a negligible problem.
For i.c. engines warming the cylinder-block reduces the oil's viscosity, and for a petrol-engine may help the fuel to evaporate, though modern cars all use fuel-injection so that may be less a problem than with carburettors.
