I use Delwalt only because they still make a couple power/battery tools in the USA. And it’s the only reason I buy them.

My batteries give the “cold temp” light when I try charge them even when as warm as 20F. So I need to bring my batteries in at night. It doesn’t take to long to warm them up if I leave them out there at night. Not sure what the magic temp is on them.
