I had a bad battery in my May 2018 Kona. California AAA tested the battery and was no longer good. They swapped in a new one. They mentioned that my car battery and idle might need to be synced up due to a new battery. He called it "flashing" the battery. Is this a thing? Could not find any info on it in the manual or online for my car. Any insight on this subject would be welcomed. Thanks.
