Is it bad to leave my power tools in a cold garage in winter? Most home garages do not have a constant heat source in them. And the indoor temperature hovers only a few degrees warmer than the outside temperature in winter. With thousands of dollars invested in quality tools in your garage, it is natural to be worried. You do not want to see permanent damage done. But, take heart, most tools will fair very well in the cold temperatures.
For cordless power tools, storing the batteries in cold temperatures can drain and damage them. The cold temperatures cause the internal chemistry of the battery to change, which leads to the charge reducing and the lifespan of the battery shortening. The best idea is to take tool batteries and store them inside the house. Keep them charged up over the winter. And by next spring, you will be ready to go.
Power tools themselves can be stored in cold temperatures. The best way to make sure though is to read the manufacturer’s directions. They may caution that certain tools should be stored over a certain temperature range. The largest caution though is that if you pull a power tool out to use during the winter, it is best to warm it first. Oil and grease can become less fluid in colder temperatures. If you use a tool in cold weather, the gears and other moving parts could be damaged without proper lubrication. Give them a few minutes to warm up in the house or in front of a portable heater. It will save you wear and tear in the long run.
Is it bad to leave my power tools in a cold garage in winter? The answer is yes and no. Those tools and batteries that need warmth should be stored in the house. The rest can be prepared to stay in the garage. Make sure they are clean and sharpened before you store them away. If they have a carrying case, pack them securely away for safety. It is a good time to inventory your tools and invest time in maintaining them. Blades should be sharpened and brushes replaced. Clean out any dust and debris on the vents and filters. When spring comes around, you are ready to begin again.
