Oh, you did it now. Invoked the chemical engineer talk.

Seriously the power pulse and equalization are not exactly the same things. The power pulse generates a frequency sweep of pulses across the plates which breaks up the crystals of deposits that form on the surface of the plates. Over time those crystal deposits become a barrier between the lead and the acid, and therefore decrease the chemical efficiency.

Battery equalization intentionally boils the acid in the battery. That does two things. One it simply stirs up the acid. The acid can stratify and become stronger at the bottom of the cell and weaker at the top. Boiling it simply stirs it up and equalizes the concentration gradient. And because the crystals that dissolve will go back into solution at a higher temperature ( like tea will hold more sugar if its hot) some of the crystals that have formed on the surface will go back into solution.

Was that clear as mud, or dense as lead?
