25-Amp Battery Charger, Maintainer & Desulfator (GENIUSPRO25)

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.

The All-New Genius Pro: Better Performance And 85% More Power

The 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. Our most powerful, efficient, and compact charger yet.

Charge Dead Batteries: Improved Start Voltage Sensor And 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.

Do More With One Charger: Multi-Voltage, Multi-Chemistry, And Multi-Battery Type

A multi-functional design that allows you to charge in more ways. Effortlessly charge multiple battery voltages (6-Volt and 12-volt lead-acid and lithium-ion batteries) chemistries (Flooded, gel, maintenance-free and AGM batteries) and types (Starter, deep-cycle, marine, powersport and more).

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.

Bring Batteries Back To Life: Auto Detection And Auto Repair

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 And 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.

Downrate Power To 5-Amps To Safely Maintain Any Size

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 With Zero Overcharge

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.

Engineered For Pros: Absolute Performance And Uncompromising Functionality

Designed for pros who need absolute performance and uncompromising functionality. Featuring ultra-flexible silicone cabling - down to -40ºC - with protective nylon braided shielding for maximum protection against abrasion and a heavy duty replaceable fuse - 35 Amp ANL Fuse - for maximum safety and performance.

Redesigned Clamps For Improved Range And Clamping Force

Genius clamps are built with needle-nose profiles for smaller terminal applications and detachable integrated eyelets for permanent mounting the accessory to battery. Designed to fit battery terminals of any shape and size. Engineered for improved clamping range, clamping force, and higher conductivity.
