## Overview

The NOCO Genius GEN5X2 is a compact, dual-bank 10A onboard battery charger engineered for 12V lead-acid and lithium batteries. It features IP68 waterproofing, smart thermal compensation, and selectable charging modes including a unique Repair Mode to revive dead batteries. Designed for marine and harsh environments, it offers flexible, independent charging with easy installation and a 3-year warranty.

## Description

The NOCO GEN5X2 is a fully-sealed, waterproof onboard battery charger rated at 10 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 GENM2, making it our most compact and advanced charger yet. Each bank operates independently, allowing you to precisely charge and maintain two 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 GEN5X2 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 GEN5X2 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: Easy install, good quality - Easy to install. Works great and so much easier that taking out boat batteries to charge every time.
Review: Great tender. - NOCO is my go to. Have this mounted in a dual battery 2500 diesel. Works great. You may need to purchase post extenders if you have a side post battery like me.

## Questions & Answers

**Q: I bought the 5 amp 2 bank and a 110 ampere hour agm battery. Will this charger be sufficient or should I return it and get the 10 amp 2 bank**
A: Yes, but it will be an extended charge time if the battery is completely dead. For example, the GEN5X2 would take roughly 22-hours to recharge a dead 110 amp-hour battery. For comparison, the GENPRO10X2 would be 11-hours.

**Q: Do the charging cables unplug or can they be extended?**
A: You can extend the leads but it’s important to make the cut in a location that only contains the 2 power conductors and avoid the 2 tiny temperature sensor wires. The charger bank will not work without the temp sensor feedback. Hint: avoid the black jacketed cable and cut where it’s obviously only two wires -  near the inline fuses.

**Q: Does this have an automatic feature? Will it shut off when fully charged and defect when low charge?**
A: The GENIUS5X2 will charge the battery fully first, then once the battery is fully charged it will stop delivering any power to the battery and will just monitor it. If the charger detects the battery's voltage drop below resting level (typically 12.8V) it will kick back in and trickle charge it back to full. Then, once the battery is full again, the charger will stop applying a charge and will go back to monitoring, and so on and so forth for as long as you leave it connected to the battery.

**Q: Do i need to have access to the buttons for this to work? can i just plug it and have it auto-charge? i have limited access where it will be mounted.**
A: The appropriate charging mode for your battery must be selected using the Mode button. The next time the charger is plugged in, it will default to the last charging mode used if a new one isn't selected.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy install, good quality
*by R***F on December 26, 2025*

Easy to install. Works great and so much easier that taking out boat batteries to charge every time.

### ⭐⭐⭐⭐⭐ Great tender.
*by T***K on February 5, 2026*

NOCO is my go to. Have this mounted in a dual battery 2500 diesel. Works great. You may need to purchase post extenders if you have a side post battery like me.

### ⭐⭐⭐⭐⭐ Great replacement the old branded battery tender plus
*by C***R on December 26, 2025*

I used these for cars that sit in storage during winter. Compared to the battery tender plus it seems better built and charges faster. Appreciate the agm mode and the on off button. I would just leave it plugged in with the battery tender but this one one can actually turn it off without unplugging. Got it on sale and think it’s a great upgrade
