## Overview

The NOCO Genius GEN5X3 is a cutting-edge, fully-sealed 3-bank onboard battery charger delivering 15 amps total (5A per bank) for 12V lead-acid and lithium batteries. It’s 37% smaller and 43% more powerful than its predecessor, featuring selectable charging modes, integrated thermal sensors for temperature-based charging optimization, and Force Mode to revive dead batteries. Rated IP68 waterproof and engineered for marine environments, it offers versatile, independent charging with a simplified mounting system and a 3-year warranty, making it the ultimate solution for professional-grade battery maintenance on boats and beyond.

## Description

The NOCO GEN5X3 is a fully-sealed, waterproof onboard battery charger rated at 15 amps total—5 amps per bank—designed for 12-volt lead-acid and lithium-ion batteries, including flooded, AGM, gel, and LiFePO₄ chemistries. It’s 37% smaller and delivers 43% more power than the previous-generation GENM3, making it our most compact and advanced charger yet. Each bank operates independently, allowing you to precisely charge and maintain three batteries simultaneously, even if they differ in type or condition. Selectable charging modes—12V, AGM, Lithium, and Repair Mode—offer tailored charging for battery health and longevity, while an integrated thermal sensor automatically adjusts charging in hot and cold climates to prevent overcharging or undercharging. For severely discharged batteries, Force Mode lets you manually begin charging from zero volts, a critical advantage for recovering deeply neglected batteries that other chargers can’t detect. Engineered for the harshest marine environments, the GEN5X3 features an IP68 rating and has endured brutal life cycle testing, including thousands of hours underwater. Installation is fast and secure in any orientation—even upside down—thanks to a redesigned mounting system with an integrated anti-vibration backing that isolates shock and noise. The GEN5X3 comes with 72-inch DC cables with 3/8-inch eyelets, a 72-inch Type-B AC cable, two mounting screws, and a user guide. It’s backed by a 3-year warranty, engineered in the USA, and certified to UL1236, ISO 8846, and 33 CFR 183.410 for safety, ignition protection, and marine compliance.

Review: Good quality, reasonable price. - Functions exactly as expected and I am now charging 2 trolling motor batteries and 1 boat starting battery with 1 plug into the outlet. Simple install on my duck boat. I added length to the trolling motor wires following the instructions on proper splicing location (after the in line fuse) and it works perfect. Charging 2 AGM trolling Motor batteries and 1 Standard lead acid deep cycle battery.
Review: Tired of Replacing Batteries from Bad Weather - I cannot store my boat at home and the storage facility does not have power. It uses three batteries that are not cheap. So I remove the batteries in the off season and keep them in great shape using this charger and conditioner in my garage. Outstanding quality. Works well. Wall mountable. Great design. Easy to use and set up. Highly advise keeping the box to store the charger then not thing. Very compact. Powerful.

## Questions & Answers

**Q: My application is a 36v golf cart (3 x 12v) - I'm assuming that I could use this for a battery maintainer (one "channel" for ea 12v battery)?**
A: Yes. Channel 1 to battery 1, channel 2 to battery 2, channel 3 to battery 3.

**Q: I have 2 group 31 Deep cycle batteries in series. Is the charge time with this charger longer leaving them connected? what's the difference?**
A: As long as there is nothing hot feeding off the battery should charge just as fast either way. Leaving the charger connected all the time won’t hurt your batteries. It will go into standby on its own once the batteries reach full charge

**Q: Can this be used for all types of standard 12V car batteries?**
A: Yes, it works on 12 and 24 volt systems. I love mine and it will also tell you if your battery  is bad. You will love it, works great!

**Q: Is it supposed to stay lit after unplugged from marina? Mine is off while the boat is out.**
A: No it doesn't stay lit when unplugged from the power supply.
