How To Charge Motorcycle Battery Using Harley Davidson 1-Amp Battery Charger

This is how I charge the batteries of my Harley Davidson Sportster Iron 883 (2021) and my Vulcan EN500 (1997) since January 2022. I use Harley Davidson 1-Amp Battery Charger.
For Harley, I use "12V AGM" Mode.
For Vulcan, I use "12V Norm" Mode.
