Designed to provide more time on the water enjoying what you like most... boating.

ProMar Digital Performance Charging

ProMar Digital Charging Performance - 12 Selectable Profiles
Up to 12 performance & precision 4-stage charging profiles: Charge, Condition, Maintain and Re-condition. Automatic dockside power mode for 12 Volt DC lighting and appliances. Factory set for Flooded (Lead Acid) batteries. AGM, GEL selectable.

Power Factor Correction - Global AC Input
Auto-ranging (100-250VAC/50-60Hz) global AC input with reduced harmonic distortion allowing all models to operate off a household power outlet connection. ProNauticP consumes less power so more AC power is available on board.

Distributed On Demand Technology
Automatically senses and distributes 100% of available charging amps to any one bank or combination of all banks.

Digital Self-Calculating Absorption and Battery Health Re-Conditioning Mode
Automatically programs conditioning time based on discharge state of batteries. Automatically de-sulfates batteries after 21 days in the maintain mode, improving reserve power performance & extending battery life.

Conservation Energy Saver Mode
After 72 hours of not seeing a load greater than 5 amps, float voltage will be lowered consuming less energy during storage periods. (for flooded & sealed charge profiles)

Service and Fault Mode LED Indicators
Real time indication of wiring faults or adverse conditions that may impact the operation of a boat's charging system.

Automatic Fan Speed Control
Quiet operation. Innovative front exhaust prevents restriction of air flow and cooling.

Automatic Temperature Compensation and Built-in Safety
Remote temperature probe included - Ignition protected and current limiting. Designed and constructed to: Marine ULc 1236, CE, CTick and FCC Class B.

WARNING: This product can expose you to chemicals including di(2-ethylhexyl)phthalate (dehp) which is known to the State of California to cause cancer, birth defects or other reproductive harm. For more information go to P65Warnings.ca.gov.

The ProMariner ProNautic 2420P is a highly advanced digital battery charger designed to meet the demanding needs of modern boats. Featuring the award-winning ProMar Digital Performance Charging Platform, this charger combines software-driven power conversion with global energy management, making it ideal for power, sail, cruising, and sport fishing vessels. It offers twelve digitally-controlled performance charging profiles that allow users to select the optimal charge mode for their specific battery type, including Flooded (Lead Acid), AGM, and GEL batteries. Each profile supports functions such as full charging, conditioning, maintenance, and re-conditioning, which helps extend battery life and improve overall reserve capacity.

The ProNautic 2420P is equipped with auto-ranging global AC input (100-250VAC, 50-60Hz), enabling it to operate seamlessly from standard household outlets worldwide. Power Factor Correction reduces harmonic distortion, ensuring more efficient energy use and less power consumption onboard. The charger features dual digital displays that provide real-time voltage and amperage readings, along with diagnostic indicators for wiring faults or adverse battery conditions, helping boaters troubleshoot issues quickly and easily.

Innovative distributed on-demand technology automatically senses and allocates charging current across multiple banks, ensuring each battery bank receives the appropriate charge based on its needs. The system also includes a self-calculating reconditioning mode that automatically determines conditioning duration based on the battery’s discharge level, with a dedicated desulfation process that improves battery health after extended maintenance periods. A conservation energy saver mode reduces float voltage after 72 hours without significant load, minimizing energy wastage during storage. The charger’s fan speed is automatically controlled for quiet operation, and an integrated temperature probe with remote sensing ensures optimal charging based on ambient conditions. Built to meet marine safety standards, the ProNautic 2420P offers reliable performance and easy maintenance, making it an essential component for maintaining battery health and ensuring reliable power during extended boating adventures.
