Why should electrical and battery-powered equipment be stored in a frost-proof place?

During the frost season, electrical and especially battery-powered devices should be stored in a frost-proof place. The reasons are: - Plastic parts become brittle at cold temperatures and are then at risk of breaking even under low force - Electronic parts/boards have components that could be damaged at very low temperatures in individual cases - Batteries lose their capacity irretrievably at cold temperatures - Batteries run down faster
