Do you have a replacement battery?

I didn't find one either, at least not on this site. There must be on out there somewhere...

Any parts we have will be on the site, we don't hide any (that just wouldn't make business sense!), so if you don't see it, we don't have it. Also, this question doesn't really belong in Answers. If you ever have a question about a part or tool that you wish to purchase, it would be better to directly contact our sales team, rather than asking the Answers community. We don't really get on here a lot, just to edit for content.
