## Overview

The NOCO GEN5X3 is a cutting-edge, fully-sealed 3-bank marine battery charger delivering 15 amps total (5A per bank) for 12V lead-acid and lithium-ion batteries. It’s 37% smaller and 43% more powerful than previous models, featuring selectable charging modes, thermal sensing, and Force Mode to revive dead batteries. Engineered for extreme marine environments with IP68 waterproofing and anti-vibration mounting, it ensures reliable, efficient charging and maintenance for multiple battery types simultaneously. Backed by a 3-year warranty and US engineering, it’s the ultimate onboard power solution for professionals who demand durability and precision.

## 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: Best bang for your buck marine charger - I purchased this 3 bank battery charger as a budget alternative for my bass boat. I have 3 12 volt batteries on board and 2 of the batteries are wired into a 24 volt trolling motor. First I’ll go over the install. If you know how to use a screwdriver and a wrench. You can install this product in your RV camper or boat. Everything is clear and simple to understand. Set up was a breeze after I got it installed. I simply selected my charging mode for my battery type. Confirmed it was on the proper voltage. And powered each bank up and away it went. It’s nice because even after you unplug it. It remembers your settings and defaults back to those settings for each bank. My first trip out with the new charger. We noticed an immediate improvement in battery life. We got an extra hour or so on our batteries on the first charge. We don’t run them dead. But I have a battery meter and I keep track of my usage and fishing times. It seems to have only gotten better as I have allowed the charger to maintain my batteries also. The batteries are on their second season and they’re functioning as if they were brand new. Durability seams very good. It gets tossed around a little in my boat and we have had zero issues with it. I haven’t yet tested out the waterproofing of the unit, thankfully. Because it is installed inside the dry area in my bass boat. Only reason I gave waterproofing a 3 star is because I cannot confirm or deny its quality or lack thereof. For a budget smart charger. These things are great. Buy with confidence!
Review: Highly recommended for boats - Can’t recommend the Noco genius enough. I mounted this in my boat and it works very good.!all you gotta do is plug an extension cord in and it does all the work. Makes charging batteries a breeze. Very simple to hook to battery’s.

## 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.
