More details on the NOCO Genius 2
Overview: The Noco Genius 2 is a portable and automatic 2-amp battery charger designed for charging cars, boats, RVs, SUVs, trucks, motorcycles, ATVs, snowmobiles, personal watercraft, hot rods, lawn mowers, and more, both 6-volt and 12-volt lead-acid and lithium-ion batteries. The Genius 2 can also be used as a battery maintainer to keep both starter and deep-cycle batteries fully charged. It also monitors battery activity for safe and efficient charging without any overcharge. The Genius 2 includes a built-in battery desulfator, in order to rejuvenate under-performing batteries, and is suitable for charging battery capacities up to 40Ah (Amp-Hours) and maintaining all battery sizes.
Charging Technology: The Genius 2 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. This efficient use of electricity not only makes Noco chargers compact, lightweight, and incredibly portable, but also minimizes energy consumption for compliance 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.
Force Mode: This mode allows the charger to be manually set, or "forced", into charging when the connected battery's voltage is too low to be detected. LED indicators will alternately flash, indicating the Genius 2 is in Force Mode. After 5 minutes, the charger will return to the normal charge operation.
Charging Modes: With the Noco Genius 2, you can simply push of a button to switch between various charging modes within one, complete multi-purpose battery charger.
- 12V (14.5V/2A): For charging 12-volt Wet Cell, Gel Cell, Enhanced Flooded, Maintenance-Free and Calcium batteries (up to 40Ah). When selected, the white 12V LED will illuminate.
- 12V AGM (14.84V/2A): For charging 12-volt advanced AGM batteries (up to 40Ah), which requires a higher than normal charging voltage. When selected, the white 12V AGM LED will illuminate.
- 12V Lithium (14.6V/2A): For charging 12-volt lithium-ion batteries (up to 40Ah), including lithium iron phosphate. When selected, the blue 12V Lithium LED will illuminate. For use on batteries with Battery Management Systems (BMS) only.
- 6V (7.25V/2A): For charging 6-volt, Wet Cell, Gel Cell, Enhanced Flooded, Maintenance-Free and Calcium batteries (up to 40Ah). When selected, the white 6V LED will illuminate.
- Force Mode (2A): For charging batteries (up to 40Ah) with a voltage lower than 1V. This charge mode will operate for 5 mins, then return to standard charging mode. When selected, all charge mode LEDs will flash while in Force Mode.
- Standby (No Power): In standby mode, the charger is not charging or providing any power to the battery. Energy Save is activated during this mode, drawing microscopic power from the electrical outlet. When selected, the orange Standby LED will illuminate.
Advanced Diagnostics: Noco chargers include built in redundant levels of safety protection for their chargers to keep you and your vehicle safe. It offers protection against reverse polarity, sparks, overcharging, over current, open-circuits, short-circuits, and overheating. Four illuminated icons can display 5 errors, Standby, Battery Voltage, Short Circuit, Reverse Polarity, and Temperature (too high/low), by lighting or flashing when a corresponding problem is detected, letting you know immediately what the problem is and how to remedy it.
Charge LEDs: The charger has four Charge LEDs (25, 50, 75, &100%). This Charge LED indicates the connected battery's state-of-charge (SOC).
- The 25% Charge LED will slowly pulse when the battery is less than 25% fully charged. When the battery is 25% charged, the red Charge LED will be solid.
- The 50% Charge LED will slowly pulse when the battery is less than 50% fully charged. When the battery is 50% charged, the red Charge LED will be solid
- The 75% Charge LED will slowly pulse when the battery is less than 75% fully charged. When the battery is 75% charged, the orange Charge LED will be solid.
- The 100% Charge LED will slowly pulse when the battery is less than 100% fully charged. When the battery is fully charged, the green LED will be solid, and the 25%, 50% and 75% Charge LEDs will turn off.
- During maintenance charging, the 100% Charge LED will pulse slowly. When the battery is topped off and fully charged again, the 100% Charge LED will turn solid green.
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 A/C power into safe D/C 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 2 includes a bracket with hook-and-loop strap for wall mounting (screws included). It is important to keep in mind the distance to the battery.

Mounted this on my generator and hard wired it to the battery. Good quality product, recommend it highly. I'm probably going to buy another one for my Side by Side. Ordered a few other things from Crutchfield recently and their service / shipping has been spot on.
