I think what he means is that the battery lifespan will improve with slower charging.
On that note, I have not seen much concrete information on how high charge rates affect all of these newer lithium batteries. They all claim outwardly that their battery can be charged fast, because let's face it... that's what consumers want. But behind the scenes they really want you to charge it slower (and not necessarily to 100%). How fast is too fast is the question I always have.
