~C~, The Other White Meat!
My bike needs to be running at about 2500-3000 rpms for the battery to be charging. What RPM does a car need to maintain in order to charge the battery? If I left it at idle, will the battery charge or do I have to drive it? Also, how long does it need to be driven/idled? Dumb question I know, and I got mixed answers when I searched. Thanks!
