The GEN4 is an On-Board Battery Charger for charging and maintaining a four bank 12-volt Marine, Starter or Deep-Cycle battery. It's waterproof, shock and vibration resistant rugged design can be mounted directly onto a variety of applications, including a boat, trolling motor or generator, as well as, a full range of electric vehicles and industrial equipment. It monitors battery activity for safe, fast and efficient charging of Wet, Gel, AGM and Maintenance Free batteries without the worry of overcharging. It's one of the most advanced charging systems designed for improved battery performance and longevity.


Fully submersible.

100% completely sealed waterproof on-board battery charger.

Designed to operate in extreme conditions with a waterproof, shock, and vibration resistant rugged construction, and has been saltwater tested to combat corrosion.





Optimization.
Stabilizes the internal battery chemistry for increased battery performance and longevity by optimizing the batteries internal specific gravity.
Maintenance Plus.
A powerful battery maintenance charge that actively monitors and manages charge cycles, but also provides a finishing charge every 24-hours, keeping batteries fully charged with zero overcharge.
Interactive.
Dynamically alters the charging process based on organic battery feedback allowing for precision battery charging.
Recovery.
When detected, it applies a high-voltage low-current pulse charge causing battery sulfation to convert back to the active material, regaining lost battery capacity.




Safe.
Protects against adverse and abnormal conditions, like reverse polarity, sparks, overcharging, over-current, open circuits and overheating.
Firewall.
NOCO chargers remain safe after a major failure. This charger has redundant levels of safety protection.
Ignition Protected.
Non-igniting and temperature controlled on-board battery charger for safe and worry-free operation.  It is Ignition Protected and meets USCH-33 CFR 183.410 requirements.
5 Year Warranty.
This on-board charger is built to last.  It's backed up with an unbeatable warranty and unparalleled customer service.

Battery Charging Times

Which on-board battery charger is right for you?

Recharging your battery fast and efficiently is essential.  Selecting the proper on-board battery charger for your application is equally important.  NOCO on-board battery chargers charge at either 4-amps per bank (GEN Mini-Series) or 10-amps per bank (GEN Series, like this one).  Whether you have a boat, trolling motor, or trailer, the GEN series charges a standard deep-cycle marine battery in less than half the time of the GEN Mini Series.

Efficient, compact design.

Compact, yet powerful on-board battery charger.

A mix of electrical engineering and industrial design creates a powerful, yet space-efficient charger that's easily mounted anywhere on your boat or equipment.  It uses high-frequency switch-mode technology to efficiently convert A/C power into safe D/C power for battery charging.  Its on-board microcomputer precisely controls the charging to minimize power loss to create an incredibly compact form factor.
The perfect companion.

Remote power access anywhere.

The GCP1 is an AC Port Plug with an integrated extension cord (16-inches) that offers optimal flexibility and ease of installation.  It can mount to the exterior of any boat, vehicle, or equipment to make the charging port accessible in a more convenient location.  Quickly plug-n-plays with any extension cord and requires zero cable modification or hand wiring.  Rated for use at 13-amps, 125-volts, and UL certified.  Fits into any standard 2-inch hole size.


Tech Tip: Using A Multi-Bank Charger

Each bank of this charger is 10 amps. Combined, this is an output of 40 amps (4 banks of 10 amps each). This is commonly used in two ways:

  • Connect each bank to separate battery systems, charging both by 10 amps each.
  • Connect both amps to the same battery system, charging it by 40 amps total.
