Newmar Phase Three PT-25W 12V 25A Marine Battery Charger
12V 25A Newmar PT charger with three-stage charging and selectable lead-acid profiles.
Marine three-stage battery charger with bulk, absorption and float operation, selectable wet/AGM/gel charging and multiple isolated outputs. Intended for permanent onboard installations where charging reliability matters. This 12V, 25A model has 3 charging outlets and suits the catalog-listed 50–250 Ah battery capacity range. Verify AC supply requirements by model because some PT units have limited or selectable AC voltage ranges.
For installation, confirm the charger’s output-bank arrangement, battery chemistry, shore-power supply and cable protection against the vessel’s system design.
