Multi-voltage. Multi-chemistry. Multi-battery type.
Charges multiple battery voltages (6V and 12V lead-acid and lithium-ion), chemistries (flooded, gel, maintenance-free and AGM) and types (starter, deep-cycle, marine, powersport and more) — all from one charger. If you need a smaller unit, the NOCO GeniusPRO range also includes models such as the NOCO Genius5 5A charger for lighter-duty use.
Progressive power supply. Uninterrupted power.
The dual-voltage power supply — 12V at 25A and 24V at 12.5A — maintains constant power delivery without ripple, noise or transient spikes during ECU flashing, reprogramming and diagnostic testing.
Engineered for professionals
Features ultra-flexible silicone cabling rated to -40°C with protective nylon braided shielding against abrasion, and a heavy-duty replaceable 60A ANL fuse for safety and performance.
Charge dead batteries
The start-voltage sensor detects and charges dead batteries as low as 1V. For batteries below 1V, force mode can be activated manually to charge batteries all the way down to zero volts.
Redesigned clamps
Needle-nose clamp profiles suit smaller terminal applications. Detachable integrated eyelets allow permanent mounting to the battery. Clamps fit terminals of any shape and size, with improved clamping range, clamping force and higher conductivity.

About the NOCO GENIUSPRO50
From our tech experts at CEN
The NOCO GeniusPRO50 is the largest charger in the NOCO range we stock: a professional charger, maintainer, power supply and desulfator for 6V, 12V and 24V batteries. It delivers 50A at 6V and 12V, or 25A at 24V, and charges lead-acid and lithium batteries up to 2,000Ah, or 1,000Ah at 24V.
Who it suits
Commercial workshops, fleets, plant and marine users with very large battery banks or 24V systems. For lighter workshop duty and banks up to 1,000Ah, the GeniusPRO25 is half the output in a smaller case.
Our tech experts advise
It draws up to 750W, so give it its own socket rather than an extension shared with other equipment. HD clamps with integrated eyelets, a replaceable 60A ANL fuse, a 10ft extension cord, an EVA case and a UK Type G power cable are included. It is rated IP20, so keep it dry.
