In general, you can store power tools in a shed or garage, even if it sometimes freezes there. However, it is better for the lifespan of the power tool to store it in a dry place without major temperature fluctuations. In a shed or garage, differences in temperature can cause condensation to form, which can cause rust. In addition, tools that run on batteries last shorter and do not charge as well at very low temperatures. To be sure how your power tool needs to be stored, always thoroughly read the user manual.
