About 6-8 years ago Menards had a really cheap sale on jump start batteries all I remember is it was really cheap. No recept. It's down to 65% charge now when plugged in. If I pull the battery out and use it in the challenge car what's fair?
No I'm not going to document, it I just want to know for my own.
I'm too cheap because I know if it was for sale at a garage sale anything more than $15 bucks I'd walk by but maybe I'm too cheap?
