Hi Mr kilmer I'm mark I have a 2013 nissan maxima with a positive terminal end problem it's so corrosion that the bolt that holds the end on it won't come off and I need to know how can i get it off or should I just get take it to my mechanic

If you've cleaned off all the corrosion and it won't come loose, even if using vice-grips, it's possible it'll need to be replaced, which on many vehicles, entails replacing the battery cable as well so as to preserve a robust connection to the battery vs trying to install an aftermarket clamp-on style replacement battery terminal which are known to be problematic.

heck, cut it off with a hacksaw, I do that all the time then put a new one on
