I found maxing out my alternator charging well depleted battery over thick copper when idling parked had my alternator quickly heat to 200 f+ degrees. But I can force.it.to seek and hold 14.7v.
The battery will accept 50% to 66% more amperage at 14.7 compared to 13.7, so actual charge rate will be determined ed by your vehicles voltage regulator.and 80%to100% charges still takes 3.5 hour at those higher. Voltages,so 'topping up' is delusional. And getting depleted batteries to 80% might fry your alternator, or just reduce its lifespan.
