I expect that was a generic answer for readers who are using AGM
batteries. Readers with different battery types are urged to start their
own darn threads else we'd all have to give all-encompassing answers to
cover all types of batteries for every question.

As my original post mentioned, my battery is a flooded cell lead-acid
deep cycle battery, and Trojan specifies 15.5V for proper equalizing for
this type battery, so it appears that the Progressive Dynamics Charge
Wizzer is not a good match. For this type of battery. Which is a flooded
cell lead-acid deep cycle battery.
