"Sulfation" in this context refers to an undesirable buildup of PbSO4 which is
difficult to completely get rid of with normal charging. Of course the lead
sulfate will still be generated during discharge cycles, but a PWM charger does a
much better job of keeping the plates clean when charged. If you examine a
lead-acid battery that has lost much of its capacity, you will probably find
large buildups of the stuff.

This technology is proven and widely deployed.
