NOCO GENIUSPRO25

25 A Smart Battery Charger & Maintainer - 6 V/12 V/24 V Automotive, Marine & Deep-Cycle

The NOCO GENIUSPRO25 is a pro-grade, 25 A smart charger and maintainer engineered for 6 V, 12 V, and 24 V battery systems. It's tailored for automotive, marine, RV, powersport, farm, and commercial applications×offering intelligent, safe, and high-power charging for large battery banks.

Features

Equipped with a smart start-voltage sensor and Force Mode, the GENIUSPRO25 can detect and revive batteries down to 1 V, or even 0 V when manually activated, making it ideal for dead batteries Capable of recovering acid-stratified or sulfated batteries automatically, it enhances battery longevity without manual intervention .

Advanced Options

The dual-voltage power supply functionality delivers 25 A at 13.6 V and 12.5 A at 27.2 V, ideal for powering or flashing ECUs, performing diagnostics, or maintaining system voltage without ripple Plus, a lower 5 A maintenance mode supports smaller batteries or long-term float charging

Product Key Features

• • 25 A charge for 6 V and 12 V batteries; 12.5 A for 24 V

  • Multi-voltage/chemistry (lead-acid & lithium with BMS) support

  • Force Mode with start-voltage sensor revives batteries down to 0 V

  • Integrated thermal compensation from -4 °F to 122 °F

  • Automatic sulfation/acid stratification repair & multi-stage charging

  • Dual-voltage power supply mode & 5 A maintenance mode

Reliability & Performance

Built for extreme environments, the GENIUSPRO25 features ultra-flexible, braided-silicone cables rated to -40 °C, heavy-duty clamps with integrated eyelets, and a replaceable 35 A ANL fuse . Its integrated thermal sensor adjusts charging voltage based on ambient temperature×from -4 °F to 122 °F×ensuring precision charging . At 375 W max power, it supports massive battery banks×up to 1,000 Ah on 12 V systems The compact form (~9.2"×5.2"×3") and lightweight (2.7 lb) make it suitable for workshop or truck use .
