The Challenger has a three stage converter which includes Absorption, Bulk and Float modes.
The converted automatically changes mode when necessary depending on conditions.
The converter in my Challenger is the WFCO Ultra III WF-9800 series.
I will add, however, that periodically checking battery water level is always a good idea.
