Fully Interactive, MCU Controlled
The NOCO Genius charger is a fully automatic and fully interactive Micro-Control-Unit (MCU), making it faster, more powerful, more reliable, and smarter than the competitive brands. What does that mean to you? The charger will adjust itself to the changing current and voltage requirements to charge and maintain your batteries.
Compact Lightweight Design
The high efficiency power conversion allows the charger to be light and compact. This charger is more versatile than other brands, and is easy to install and fit into tight locations.
Designed for Safety
Each of NOCO Genius chargers contains multiple safety features to protect against user errors. These safety features include: reverse polarity, short circuit, open circuit, over-temperature, over-charging, and spark proof battery hook-up.
Energy Efficient, 90% Efficiency
The NOCO Genius charger is 90% efficient. Why is that important? The higher the efficiency level, the lower the power waste. Unlike other battery chargers, which waste almost half of their rated current, the NOCO Genius charger always performs at an optimal level.
Leaving a battery in permanent maintenance charge mode reduces battery life. In fact, most battery manufacturers recommend against it. That is why this charger shuts off when the charge sequence is complete. Then turn "On" every 24 hours to ensure proper maintenance of your battery and making sure your batteries are 100% charged.
Made in the USA
Designed and manufactured in the USA. With a research and development facility in Arizona and manufacturing facility in Ohio, NOCO has the ability to consistently produce the highest quality and the lowest return in the industry.
Stage 1 & 2 - Diagnose and Test
Checks the battery voltage to make sure battery connections are good and battery is in a stable condition.
Stage 3 - Soft Start
Begins battery charging process with a gentle charge.
Stage 4 - Bulk Charge
Begins Bulk battery charging process, returns 80% of battery capacity and voltage to 14.0 volt.
Stage 5 - Absorption Charge
Switches to a constant current charge rate to bring your batteries close to 90% charge.
Stage 6 - Taper Charge
Charges at low current levels until battery has reached 95% of its capacity
Stage 7 - Top-Off Charge
Charger initiates top-off charge to bring the battery to 100% charge.
Stage 8 - 24 Hour
Shuts off, but constantly monitors your battery by providing a gentle charge every 24 hours for maximum battery life.
