Two-Stage Charging
If the two-stage charge is enabled, the charger finishes the absorption
charge but does not go to float mode because some battery manufacturers
advise against floating their batteries. The RS3000 goes into a monitoring
mode instead where the charger monitors the batteries but does not float
them.
A new two-stage charge cycle will be initiated under the same conditions
as for three-stage charging.
