NOCO Genius GENIUS2D 6V 12V 2Amp UltraSafe Battery Charger and Maintainer Engineered and tested to withstand rugged working environments, like high-heat engine compartments, shock, vibration, and even water exposure. The GENIUS2D is the ultimate mountable on-board battery charger and battery maintainer for any car, boat, truck, RV, or equipment, and is designed to be located in close proximity to the battery. Introducing the next-generation of battery charging with the all-new maximum power density technology. This smart charger has insanely high performance and it is designed to be the most compact, lightweight and energy efficient charger on the market. Using advanced power conversion topologies as its foundation, the Genius 2D has significantly increased the power-to-space ratio utilizing power magnetics, consolidated components, and innovative thermal management techniques. 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. The GENIUS2D now features an integrated thermal sensor that automatically monitors and adjusts the charging cycle based on fluctuations of ambient temperature, enabling it to provide more precision charging in both hot and cold climates. Not only does it increase charge performance, but it extends battery life by limiting the impact of under-charging/over-charging caused by temperature changes. So now when you are charging in cold temperatures, the charging rates increase, and when in hotter temperatures, the rates will decrease. The result, better, more accurate, fully-charged batteries.
