Product Research

Features

Overview: The Noco Genius 2D direct-mount battery charger and maintainer is compact, energy-efficient, and designed for all types of 12 volt lead-acid batteries, including flooded, gel, AGM (Absorbent Glass Mat), and maintenance-free, for automotive, marine, RV, and deep-cycle batteries. The Genius 2D monitors battery activity for safe and efficient charging without any overcharge, and is suitable for charging battery capacities up to 40Ah (Amp-Hours) and maintaining all battery sizes.

Charging Technology: The Genius 2D smart battery charger utilizes the latest advancements in battery charging technology. It's built on a high-frequency and high-efficiency platform, which converts energy 30,000x faster than traditional automotive battery chargers. It's this efficient use of electricity is what makes Noco chargers not only compact, lightweight, and incredibly portable, but one that minimizes energy consumption and compliant with California Energy Commission regulations.

Intelligent Maintenance Technology: Most manual, automatic or semi-automatic battery chargers continuously trickle charge batteries, making them susceptible to overcharge, which limits battery life. Noco's intelligent battery maintenance technology monitors battery activity and only begins charging when needed, and allows for continuous operation without user intervention and zero risks of overcharging your battery. An integrated thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates. The charger can be left connected to the battery indefinitely.

Efficient & Compact Design: A mix of electrical engineering and industrial design create a powerful battery charger into a tiny footprint. It uses high-frequency switch-mode technology to efficiency convert AC power into safe DC power for battery charging. And it's onboard microcomputer precisely controls the charging to minimize power loss to create an incredibly compact form factor.

Mounting & Installation: The Noco Genius 2D includes a bracket with a hook-and-loop strap that allow it to be mounted in close proximity to the battery. The Genius 2D is outfitted with an attached 2' AC power cord and a 2' DC cable. The AC power cord is terminated by a two-prong AC plug, while the DC cables are terminated with ring-terminals (0.60" outer diameter/ 0.41" inner diameter).

Rugged Construction w/ 3 Year Warranty: The Noco Genius 2D charger & maintainer is designed for a rugged working environment. It's water, shock, dirt and dust-proof, and carries an IP65 weather-proof rating. Noco battery chargers are built to last and are backed with a 3 Year Warranty.

Charging Times: The estimated time to charge a battery is shown in the table below. The size of the battery (Ah) and its depth of discharge (DOD) greatly affect its charging time. The charge time is based on an average depth of discharge to a fully charged battery and is for reference purposes only. Actual data may differ due to battery conditions. The time to charge a normally discharged battery is based on a 50% DOD.

Battery Size (Ah) Approximate Time to Charge (Hours)
12V
8 2
12 3
24 6
40 10

Charge LED: The charger has 1 Charge LED that indicates the connected battery's state-of-charge (SOC).

  • 75% Charge: The Charge LED will slowly pulse red when the battery is less than 75% fully charged. 

  • 100% Charge: When the battery is between 75% and 100% charged and during battery optimization charging, the Charge LED will slowly flash green. When the battery is 100% charged, the Charge LED will light solid green.

Diagnostics: Three front-panel LEDs, Error, Hot, and Standby, can indicate the following problem conditions:

  • Error: This lights if reverse polarity is detected, or if the battery voltage is too low for the charger to detect.

  • Hot: Lights if the charger is outside of its safe operating temperature and is not charging.

  • Error & Standby (single alternating flash): The battery won't hold a charge.

  • Error & Standby (double alternating flash): Possible battery short.

  • Error & Standby (triple alternating flash): Battery voltage is too high.
