NOCO Genius PRO 25 6V/12V/24V 25A professional battery charger

The NOCO Genius PRO 25 is a fully-automatic professional 25 A smart battery charger for 6 V, 12 V and 24 V batteries with maintainer, desulfator, power supply and thermal compensation functions. It is built for workshops, service shops and commercial vehicles — cars, vans, trucks, buses, boats and equipment with large lead-acid or lithium-ion batteries.

Genius PRO 25 supports every lead-acid type (flooded, gel, AGM, MF) and lithium-ion (LiFePO4), across chemistries and battery types (starter, deep-cycle, marine, powersport). The dual-voltage power supply delivers constant 12 V at 25 A and 24 V at 12.5 A — ideal for ECU flashing, reprogramming and diagnostics without ripple or transient spikes.

A dedicated 5 A reduced charge mode safely maintains smaller batteries or supports long-term storage. The integrated thermal sensor adjusts the charging cycle from -20 °C to +50 °C, and the all-new Force Mode manually charges flat batteries below 1 V — down to 0 V — with cutting-edge repair modes for 6 V, 12 V and 24 V.

Engineered for pros: ultra-flexible silicone cabling rated to -40 °C with nylon-braided shielding for abrasion resistance, a heavy-duty replaceable 35 A ANL fuse, and clamps with detachable eyelets for permanent installation.
