The NewMar PT-14W is a professional-grade three-stage battery charger designed for 12-volt marine applications including recreational boats, workboats, military vessels, and commercial craft. This intelligent charger delivers 14 amps of charging current across three isolated output banks, providing optimum charging for multiple battery systems simultaneously.
Smart Three-Stage Charging Technology:
The PT-14W employs advanced "Smart" charging circuitry that automatically manages the complete charge cycle through bulk, absorption, and float stages. This optimized process ensures fast battery recovery, proper conditioning, and extended battery life. The charger can be used with or without batteries connected, functioning as a clean, regulated power supply for direct load operation.
