I live where it gets wintery cold (-25C), and make sure to bring
in my rechargeable batteries and the chargers. But how about the tools themselves? Like a weed whacker and a hedge trimmer. Are they good to stay out in the mud room? Or do I need to bring them into the warm house for the winter?
I’m never sure!
I recommend reading the user manuals for these tools. The operating temperature range may be provided along with the storage temperature range. If you don’t still have the printed manuals, the manufacturer website should have the manuals in PDF form.
The batteries are the big risk. As long as you’re not bashing them around in - 25 degree weather, the tools will be fine. I’ve been storing mine outdoors for 10 years.

I haven’t had a problem leaving rechargeable tools (hedge trimmer, chainsaw) in the garage during the winter months (we can get down to the single digits below zero, rarely colder).
Batteries do come indoors for the winter.
Also note that rechargeable batteries will not charge when below freezing. This is more applicable to things like battery-powered security cameras than yard tools.
I leave all of my yard tools in a shed that is quite a distance from the house–if it hits zero F out there, the shed is zero F inside.
The only thing that ever died was a pressure washer. Actually two of them died. It took two pressure washer deaths before I realized that a machine that would likely retain water internally when shut off would not fare well through a freeze-thaw cycle.
(and I do realize this stretches the question of the OP a bit since they aren’t rechargeable)
