Is there a method to replace battery other than connecting a known good 12v battery to battery cables in the car, remove old battery, install new battery, connect terminals to new battery in the car, and then remove cables to that you initially installed to battery cables. I have heard about 9v battery in cigarette lighter,... not to keen on this idea.
What problems will you have if you just replace battery without keeping 12V applied to battery cables? And how to you recover from those problems?
