The NOCO GENIUSPRO25 is our most advanced, high-performance battery charger yet—building on the legacy of the G15000 with more power, more functionality, and professional-grade speed. Designed for those who demand the best, this world-class charger delivers up to 25 amps for 6-volt and 12-volt systems and 12.5 amps for 24-volt systems, supporting all types of lead-acid and lithium-ion batteries, including flooded, gel, AGM, maintenance-free, and deep-cycle—up to 1,000 amp-hours for 6V and 12V, and up to 500 amp-hours for 24V. Built for pros, the GENIUSPRO25 features ultra-flexible silicone cabling that remains pliable down to -40ºC, protected by a braided nylon outer layer for maximum durability against abrasion and wear. It doubles as a progressive power supply—delivering 12V (25A) and 24V (12.5A) output—to maintain clean, stable voltage during ECU flashing, diagnostics, and reprogramming without ripple, noise, or voltage spikes. An integrated thermal sensor ensures precision charging by adjusting based on ambient temperature to prevent overcharging in heat and undercharging in cold environments. The GENIUSPRO25 can detect and charge batteries as low as 1-volt—or down to zero volts using the all-new Force Mode—and includes advanced battery restoration modes to repair and reverse sulfation and acid stratification across 6V, 12V, and 24V batteries. Whether you’re servicing automotive, marine, or deep-cycle systems, the GENIUSPRO25 gives you the power, control, and reliability to push the limits of battery performance.
- MEET THE NOCO GENIUSPRO25 — Similar to our G15000, just more powerful. With the greatest performance and functionality yet, it’s a world-class battery charger to let professionals push the limits at incredible charging speeds.
- DO MORE WITH GENIUS — A multi-voltage charger – 6-volt (25-amps), 12-volt (25-amps), and 24-volt (12.5-amps) – for lead-acid automotive, marine, and deep-cycle batteries, including flooded, gel, AGM, and maintenance-free, plus lithium-ion.
- ENGINEERED PRO PROS — Designed for pros who need absolute performance and uncompromising functionality. Featuring ultra-flexible silicone cabling – down to -40ºC – with protective nylon breaded shielding for maximum protection against abrasion.
- PROGRESSIVE POWER SUPPLY — A dual-voltage power supply – 12-volt (25-amp) and 24-volt (12.5-amp) – to maintain constant power delivery without unwanted ripple, noise, and transient spikes during ECU flashing, reprogramming, and diagnostic testing.
- ENJOY PRECISION CHARGING — An integrated thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates to maximize battery life and enable fast charging.
- CHARGE DEAD BATTERIES — Detects batteries as low as 1-volt. Or use the all-new force mode that allows you to manually begin charging dead batteries down to zero volts.
- RESTORE YOUR BATTERY — Automatically detects battery sulfation and acid stratification to restore lost battery performance for stronger engine starts and extended battery life. Plus, cutting-edge battery repair modes for 6-volt, 12-volt, and 24-volt batteries.
