NOCO GENIUSPRO25: 25A 6V/12V/24V Professional Battery Charger, Maintainer and Desulfator

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.
