## Overview

The NOCO GEN5X1 is a compact, 5-amp single-bank onboard battery charger engineered for 12V lead-acid and lithium batteries. Featuring selectable charging modes, thermal compensation, and Force Mode for dead battery recovery, it boasts an IP68 waterproof rating and marine-grade durability. Designed for easy installation with anti-vibration mounting, it ensures reliable, precise charging in the toughest environments, backed by a 3-year warranty and US engineering.

## Description

The NOCO GEN5X1 is a fully-sealed, waterproof onboard battery charger rated at 5 amps, 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 GENM1, making it our most compact and advanced charger yet. With a single dedicated charging bank, the GEN5X1 offers precise charging and maintenance for one battery with selectable modes—12V, AGM, Lithium, and Repair Mode—tailored to maximize battery health, performance, and longevity. An integrated thermal sensor automatically adjusts the charge based on ambient temperature to prevent overcharging in heat or undercharging in cold conditions. For severely discharged batteries, Force Mode allows manual charging down to zero volts—ideal for reviving deeply neglected batteries that most chargers cannot detect. Built for the harshest marine environments, the GEN5X1 carries an IP68 rating and has passed extensive life cycle testing, including thousands of hours underwater. Its streamlined mounting system enables fast, secure installation in any orientation—even upside down—with an integrated anti-vibration backing to minimize shock and noise. The GEN5X1 includes 72-inch DC cables with 3/8-inch eyelets, a 72-inch Type-B AC cable, two mounting screws, and a user guide. Backed by a 3-year warranty, engineered in the USA, and certified to UL1236, ISO 8846, and 33 CFR 183.410, the GEN5X1 delivers unmatched reliability, safety, and performance.

Review: Excellent quality battery charger and maintainer - I puchased this to keep the expensive type 31 batterys from sulfating on my John Deere backhoe. So far it has performed admirally. I like the fact that it has the capability to charge a totally dead battery if needed, which most other charger / maintainers won't do. I selected Noco over the brand I used to buy after seeing a comparative product review on the "Project Farm" YouTube channel.
Review: Good product - This works very well for me. It was an easy installation and has done everything I've asked it to do

### ⭐⭐⭐⭐⭐ Good product

This works very well for me. It was an easy installation and has done everything I've asked it to do

### ⭐⭐⭐⭐⭐ Great chargers
*by G***. on December 12, 2025*

I have had several of these units over the years, and have no issues with them. I've had the two bank mounted on a boat, a single Bank mounted on a car that's in storage, a dual bank that I use on a utility cart. No issues with any of them. For my latest project I use this for a spray rig. I have a deep cycle battery inside of a battery box, and have the single Bank unit mounted on the outside to charge my deep cycle battery.
