Batteries are a big business in Canada for assembly and finishing happens in China for the most part. I think Japan makes their own. There are existing plants for Duracell and a few others here. Too lazy to look up but Sleepy Hollow or whatever needed a big cleanup at an abandoned plant.

I just go by what I see. Turn over a plastic item and look where it was made. I have a several hundred buck telescoping ladder I work with. Nice aluminum ladder "Made in China" 3 companies make telescoping ladders. Not a one of them is made in this country.

I could be wrong. I hear complaints all the time that building a new factory in the U.S. is nearly impossible.

I try to aggravate one person a day. Today may be your day.
