The mat is microporous low energy charging when a battery is depleted does not impact plates that are surface dried. High energy drives which means circulates fresh acid throughout the mat and reverts the plate surface. Another benefit of the lifeline -- more acid per square surface area.
Slow and incomplete is like a starving person with a 3" plate of food being yanked away from the table after a few minutes of eating. Like putting a malnourished person on a diet.
This is the basis of my saturated charging.
Course a person could stick with a doubtful attitude and make the battery distributor pee his pants in gratitude Lyrical No/Yes?
