Sorry if this is a FAQ; I searched the site but found nothing exactly on point. I bought a new Konnwei battery tester and ran the test on my 2018 Premier's battery (purchased 8/18) after disconnecting both positive and negative cables. Selected AGM flat plate 520A. Here's the readout. Does this indicate I'll soon need a new battery? Hard to interpret "Charge and Retest" when I basically leave the car plugged in at all times, so the internal system should keep the 12V battery fully charged. Thanks for any advice.
