Low Battery, See Dealer. Just Replaced Battery With AGM
I've been getting the red warning, so I replaced the main battery with a Duracell AGM from Sam's Club. However, I'm still getting the warning and tired of looking at it every time I start the car.
I checked voltage using the "hidden" menu. At rest, the battery holds 12.3-12.4V. When starting, it dips to about 9-10V, and when running, holds extremely steady at 13.9-14.0V.
Should I replace my aux battery to be sure?
