Battery chargers like converters come in two basic types (Times a bunch on Chargers)
Smart and "Dumb"
The Magnetek 6300 series (As an example of a Dumb converter) was well known as a bnatery killer,, Why, because it did not have the "Smarts" to know when to quit so it kept on a-charging and a-charging even though the battery was full.
Many multi-amp chargers are like that (I do not know nor do I intend to research the one you have).
On the other hand the Progressive Dynamics 9200 line is a SMART converter/charger, it DOES know when to stop.
And so do the "Smart" automotive chargers.
