 You know, it's a great question, Tom. It really is, and it is a concern. I will answer it like this, if I can, with a little story. So, you know, we stock batteries at the shop, and we just stock, I think, 10 or 12 of the common popular numbers and some of the not-so-common popular numbers. And I count on the battery truck to come around every couple of weeks, and he'll look at the date code on the battery and say, yeah, this one's got to go, this one's got to go, and they rotate your stock around.
