I have a 2010 GMC Yukon Denali, 158,000 miles. I tested it with my Topdon ArtiBattery101 and it says the Battery & starter are fine but charging is high. Loaded voltage is 14.65V and Unloaded is 14.81V. Ripple is 20mV. Does the alternator need to be replaced right now? Thanks!

@mountainmanjoe Should I even worry about it at this point? I read that 14.8V is high for an alternator. I don't want anything to get damaged.
