NOCO® GENIUSPRO25 6V/12V/24V 25-Amp Smart Battery Charger

Introducing the all-new GENIUSPRO25, a 6-volt,12-volt, and 24-volt fully-automatic professional smart charger, maintainer, power supply, and battery-desulfator with temperature compensation rated at 25-amps for all types of automotive, marine, and deep-cycle batteries.

More Power. Better Performance
Our Most Powerful, Efficient, and Compact Charger Yet.The all-new 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.

Charging
Improved Start Voltage Sensor. All-New Force Mode. The all-new start-voltage sensor allows the GENIUS to detect and charge dead batteries as low as 1-volt. For extremely dead batteries lower than 1-volt, manually turn on force mode to detect and charge batteries all the way down to zero volts.

Multi-Voltage. Multi-Chemistry. Multi-Battery Type
A multi-functional design that allows you to charge in more ways. Effortlessly charge multiple battery voltages (6-Volt, 12-volt, and 24-volt) for lead-acid automotive, marine, and deep-cycle batteries, including flooded, gel, AGM, and maintenance-free, plus lithium-ion.

Thermal Compensation
More Precise Charging in Any Climate. The new integrated thermal sensor automatically monitors and adjusts the charging cycle based on fluctuations of ambient temperature, limiting the chance of under-charging or over-charging, providing a more accurate and fully charged battery. Avoids under-charging in cold weather down to -4 F and avoids over-charging in hot weather up to 122 F.

Batteries Back to Life
Auto Detection. Auto Repair. Improved Performance. The all-new GENIUS automatically detects sulfation/acid stratification. If any is found, the GENIUS will automatically repair and reverse the damage done to the battery, extending the usable life and increasing performance for stronger engine starts. Plus, cutting-edge battery repair modes for 6-volt, 12-volt, and 24-volt batteries.

Dual-Voltage Power Supply
Progressive Power Supply. Uninterrupted Power. 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.

Safely Maintain Any Size
Downrate Power to 10-Amps. The GeniusPRO25 is equipped with a reduced charge current mode that allows the unit to operate at 5A for optimized charging of smaller batteries or continual maintenance.

Completely Automatic
Year-Round Charging. Zero Overcharge. Auto Memory. Finally a charger from start to finish that’s completely automatic. No special modes, no technical knowledge required. Genius will safely charge any battery. Detect damaged batteries and intuitively repair them. And actively monitor for long-term battery maintenance and extend battery life. This system allows for continuous operation without user intervention, and zero risk of overcharging your battery.
