I concur with that myth, but does anyone have peer reviewed articles on
the pulse desulfinators? I've read the patents, but I haven't seen any
objective testing.
I have several smart chargers with this feature. Notably, if you want to
use it, you must disconnect (isolate) the battery. It is not clear to me
that I have had any better results with this, than if I kept a trickle
charger on the battery. The trickle charger would have kept it fully charged.

Since this is the major reason lead acid batteries go bad, it is a good thing to do. Battery is now 2 years old but has spent most of its time sitting in my garage rather than being used on the camper. BTW it is a myth that a battery will go bad if it sits on a concrete floor. Hayden
