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.

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 for 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.

Meet the GENIUS5 - It's the all-in-one solution - battery charger, battery maintainer, trickle charger, plus battery desulfator.
