NOCO 12V 40Ah 12V Lithium Ion LiFePO4 Dual Purpose Battery (NLXU1)

*Compatible with button head bolts, SAE terminal posts, and threaded rods for secure mounting and with Group U1 BCI Size.

Upgrade your power setup with the NOCO NLXU1 12V 40Ah Lithium‑Ion LiFePO4 Dual Purpose Battery — a high-performance, lightweight, dual-purpose powerhouse designed to replace standard lead-acid Group U1 batteries and crush the limitations of conventional batteries.

Engineered for both starting and deep-cycle applications, this battery brings elite features that let you go further, longer, and with more confidence.

Key Features & Benefits:

• 12 V nominal voltage with 40 Ah capacity (512 Wh) — delivering serious usable energy for both starting and deep-cycle use cases.
• Massive 600 amp peak starting current (with a continuous discharge capability of 75 A) — ensures solid engine starts and high-load acceptance.
• Lithium iron phosphate (LiFePO₄) chemistry — offers vastly improved life span, no sulfation, lighter weight compared to lead-acid, and better performance in varied conditions.
• Professional BMS (Battery Management System) built in: Active protection against over-charge, over-discharge, short-circuit, temperature extremes and cell imbalance — maximizing reliability and safety.
• IP66 waterproof rating — rugged protection from dust and water intrusion makes this battery suitable for harsher environments and powersport / marine applications.
• Multiple terminal connection options included: Type X terminals, 3/8″-24 × 9/16″ bolts, 1/4″-20 × 7/16″ bolts, plus terminal covers and hex keys — allows flexible mounting and fitment in a wide variety of vehicles and equipment.
• Fits BCI Size Group U1 — direct fit in many standard applications making replacement and upgrade effortless.
• Exceptional weight: only 12 lbs (5.44 kg) — in many setups you’ll cut weight significantly, improving performance and handling.
• Backed by a 5-year limited warranty — showing the manufacturer’s confidence in long term performance.

Why This Battery Stands Out:

• Offers 2× more power, 10× more starts, 2× more capacity and up to 20× longer life compared to traditional lead-acid alternatives.
• Rapid recharge capability: when used with compatible chargers (e.g., Genius line), the NLXU1 can recharge in as little as ~0.8 hours (with high-amp charger) or ~1.6 hours with moderately fast charger — dramatically faster than lead-acid batteries.
• Designed for both starting duty (as in powersports, ATVs, UTVs, small boats) and deep-cycle duty (such as onboard accessory banks, trolling motors, backup power) — delivering dual-purpose flexibility.

Ideal Use Cases:

• Powersports vehicles: ATVs, UTVs, jet skis, snowmobiles where lightweight and high starting power are key.
• Small marine craft or trolling motor systems requiring a reliable lithium upgrade in a compact Group U1 footprint.
• Vehicle accessories and backup power setups (e.g., winches, lights, audio) where deep-cycle capacity and reliability are critical.
• Anyone upgrading from old lead-acid Group U1 batteries seeking to reduce weight, increase lifespan, and improve performance in cold/hot conditions.

Installation & Fitment Insights:

• Designed to fit the standard Group U1 size footprint: Height ~6.69″ (170 mm), Width ~7.75″ (197 mm), Depth ~5.19″ (132 mm).
• The bundle includes multiple terminal bolts and covers for flexible wiring/connection options; the Type X terminal system allows mix-and-match mounting to fit many chassis.
• While lighter and more robust, ensure that your charger is compatible with LiFePO₄ chemistry or that you use the correct charge program (the manufacturer recommends charging at 14.6 V and using a charger suited for lithium).
• Because the BMS protects battery from deep discharge, it’s ideal for applications where reliable standby/power reserve is needed — unlike older batteries that degrade quickly under cycling.

If you’re ready to step up from bulky, heavy lead-acid batteries and shift into the future of power, the NOCO NLXU1 delivers a premium upgrade. Lightweight yet tough, high starting power yet deep-cycle capability, rapid recharge and rugged build — it’s the kind of battery that changes expectations.

Whether you’re looking to hit the trails, tackle marine adventures, or install a high-reliability accessory power system, this battery is engineered to perform and built to last.
