The NOCO GENIUSPRO50 Genius PRO 50 Multi-Voltage Battery Charger can jump-start 12V and 24V lead-acid automotive, marine, and deep-cycle batteries, including flooded, gel, AGM, and maintenance-free, plus lithium-ion batteries. For use with cars, trucks, RVs, tractors, aircraft, and other large vehicles and equipment, the Genius PRO comes with silicone-coated cables wrapped in braided nylon that are abrasion resistant and designed to be flexible in weather as cold as -40°F. The cables come with an integrated replaceable 35-amp ANL fuse, and the battery clips have integrated eyelets for permanent mounting to the battery. The start-voltage sensor detects voltage down to 1V, and features a manual mode for charging batteries that register zero volts. The dual 25A, 12V / 12.5A, 24V power supply maintains constant power delivery without unwanted ripple, noise, and transient spikes during ECU flashing, reprogramming, and diagnostic testing. A 10-amp downrate mode is provided for charging smaller batteries.

The Genius GENIUSPRO50 PRO will check the temperature and tailor the current to eliminate overcharging in hot climates and under-charging in cold climates. The charger will detect sulfation or acid stratification that impair the battery's performance and repair the damage. You can leave it plugged in and attached for battery maintenance with no worries about overcharging.
