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.

24-Hour Mode

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.

Designed in the USA

Designed 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.

Great charger for maintaining an AGM group 31 battery
June 27, 2020
by on June 27, 2020

I've purchased several of these for use both at home and for our business and also recommended it to some of our customers for use in maintaining their various batteries.

This is a robust, simple to use, workhorse of a battery charger.

It's not light weight, but that's O.K. as it will outlive and provide dependable service for a long time.

Highly Recommended for any battery maintenance condition.

needed something to keep my RV battery charged without overcharging This unit does just what I hoped it would. The folks at Batterymart (Julia) were very helpful, and the charger was shipped right away. All in all, a very good experience dealing with Batterymart

I have a 2007 Silverado Classic that loves to eat batteries. The computers always activate while parked and consume as much as 4 Amps of power at a time. I-2 Amp chargers can't keep up with this drain, and a battery sulfates early and goes dead. Hence, the factory recommends battery replacement every two years. I managed to get 7 years out of my OEM battery with a 10 Amp solar charger. Recently, the solar charger went bad, from water on my now three year old AGM battery. So, I've replaced it with this NOCO 10 Amp sealed unit. I brought the AGM back to full capacity, and the NOCO Gen 1 10 Amp is keeping it where it should stay while parked. With only 12,000 miles, my truck is still new and stays parked a lot.

This NOCO Gen 1 is large and heavy, but I managed to find a good spot to mount it on the passenger side under the hood near the firewall. The wiring was long enough to make it look factory under my hood with the addition of webbed nylon wiring loom. Best of all, the NOCO Gen 1 is worry free.

Great charger

This is a great piece of equipment! Just plug it in or leave it plugged in. Charges quickly and shuts itself off when the battery is fully charged. I highly recommend it.

This is the new 10 amp single bank charger and it was just what I was looking for. Bought it in June 2016 to replace a ProMite 5/5 10 amp which replaced a Guest 2611 2 bank 10 amp charge. I has been working great and charges my group 27 great. Will probably by another just to have before it becomes discontinued.

Pictures can be deceiving

We are testing the charger in our medical carts and so far it performs well. It has a rugged construction which we prefer. But the big flaw we noticed immediately was the size and mounting was totally different then what the picture and dimensions were listed. We are very limited in space and size which is almost as important to us as functionality. The charger was at least an inch bigger in every
