It’s 37% smaller and 43% more powerful than previous models, featuring selectable charging modes, thermal sensing, and Force Mode for dead battery recovery. Rated IP68 waterproof and engineered for harsh marine environments, it offers versatile, independent charging with easy installation and a 3-year warranty. ## 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. ## Features - MEET THE GEN5X3 — 37% smaller and 43% more powerful than the GENM3.

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. ## Frequently Bought Together - NOCO Genius GEN5X3, 3-Bank, 15A (5A/Bank) Smart Marine Battery Charger, 12V Waterproof Onboard Boat Charger, Battery Maintainer and Desulfator for AGM, Lithium (LiFePO4) and Deep-Cycle Batteries - NOCO GCP1 15A AC Port Plug, 125V Power Inlet Socket, and Waterproof Electrical Outlet Receptacle Box with 16-Inch Integrated Outdoor Extension Cord - NOCO Genius GEN5X2, 2-Bank, 10A (5A/Bank) Smart Marine Battery Charger, 12V Waterproof Onboard Boat Charger, Battery Maintainer and Desulfator for AGM, Lithium (LiFePO4) and Deep-Cycle Batteries --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/249554814-noco-gen5x3-12v-15a-3-bank-onboard-marine-battery-charger](https://www.desertcart.jp/products/249554814-noco-gen5x3-12v-15a-3-bank-onboard-marine-battery-charger) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-30*
