This thing is amazing. I installed it just before Christmas, then I left for work for 1 month, Jan 16th to Feb 16th. During that time we had a cold snap down to -35 C. When I came back my truck started right up no hesitation. If you are thinking about getting this don't wait. Just do it you'll have no regrets

Just bought a used truck in the northern Canada that is on a lead acid battery with a badly wired updated head unit, this has been great to have to keep the battery topped off while I wait for the winter to end so I can rewire the thing without freezing my ass off. I have it running off and extension cord that also powers my bloc heater

Great product. I have two of these. One is hooked up to my ram 1500 which isn’t driven much and the other one is hooked up to my atv when it’s not being used. I find that both the truck and atv have easier starts with the maintainer being used.

Easy to install and as said, limited installation options due to short cord length and including a cover for electric plug would be great.

I purchased the NOCO Genius2D, and it has exceeded my expectations! i have a Jeep that sits a significant amount of time. it hadn't been driven in nearly 7 months and the battery was stone dead!The installation process was straightforward. The included mounting bracket and eyelet cables made it easy to secure the charger near the battery. The 24-inch A/C and D/C cables provided ample length for a neat setup.This charger works flawlessly! After installing it, I left it plugged in overnight and by the next morning, the jeep started easily! It efficiently maintains the battery charge, ensuring my Jeep will always be ready to go! The charger also features short-circuit, over-voltage, and reverse polarity protection, which gives me peace of mind. Even if I mess up, I'm protected!The charger is very compact, which is a big plus. It fits easily under the hood without taking up much space. The IP65 rating for water and dust resistance is a great feature, especially for driving in various weather conditions.Considering its performance and features, this charger offers excellent value for its price. It’s a reliable and efficient solution for maintaining my vehicle's battery.Overall, I’m very satisfied with the NOCO Genius2D. It’s a high-quality, dependable charger that I would recommend to anyone in need of an onboard battery maintainer.

Pretty straightforward installation into 2002 F150 with a few extra materials. I didn't have many good options to screw directly, so I made a simple plastic sub-plate & attached the included holder clip to that & used 2" wide Velcro to the cover plate as shown. Both the battery leads & cord were long enough to orient like so. I had some spare plastic cable armor tubing so used that over the length of plug wires. More importantly, once plugged in, the NOCO did its thing, LED lights sequenced through charge status as they should. It floated an iffy battery from 11.x to 12.4V & is overcoming what I'm sure is a slow drain somewhere in the electrics which costs me a replacement battery every 2 years. So far so good. Hopefully it will do its job for a long time.

I was in the market for a trickle charger that was small enough to hard mount onto my recently acquired Outlaw 110 - saw this, took a few measurements and hit our all time favorite button.... "Buy Now".A few days later and it shows up - packaging is great, has instructions for those who need them, and the physical base unit itself was small enough to neatly tuck next to the Air box (L-side) and secured to the frame. Just enough length on the outlet cord to run along the frame and have it restored just behind the LF headlight for ease of access.... Couldn't have asked for a better product.It charges the YTZ7S battery fantastically! Came up to it this morning after two days of rest and it's keeping the battery happy and healthy. Will be purchasing again!

Purchased because I don’t do a lot of driving and last winter I needed several jump starts, even when the weather wasn’t extremely cold. V annoying!! (Lexus tells me that the electronic anti-theft mechanism is a particular drain on battery power). I had bought the Noco GB70 for this and was already “brand friendly” because of the positive experience. The Noco Genius 2D did not disappoint. It was smaller and lighter than expected. Installation was a little tricky because there wasn’t much space within the maximum two feet radius from the battery terminals (the length of the O-ring terminal wires) and because I needed a suitable surface to screw on the small mounting bracket. Eventually I popped off the front plastic cover shielding the radiator and fan belt and found a spot just behind the upper front grille. This allowed me to install the charger AND run the power cord out through the front grille, secured with a plastic tie. I hooked it up to the external power cord and confirmed that the LED read-outs were doing their job (flashing red - charging; solid green - charged). No problem. I then replaced the front engine cover, hiding the Noco 2D from view. I trust Noco that it will keep working, out of sight. OK winter, do your worst. I’m ready for you.JH Toronto

As an avid car enthusiast, maintaining the health and longevity of my vehicle's battery is of utmost importance to me. The NOCO GENIUS2D 2A Direct-Mount Intelligent Onboard Battery Charger has been an absolute game-changer in ensuring that my car battery stays charged and ready to go at all times. This intelligent onboard battery charger is specifically designed for 12V car batteries, and after using it for a while, I can confidently say that it is a fantastic investment for any car owner.lug inI live in Canada and we have cold winters where we need block heater to keep the engine warm in -30F nights. I Use a double plug-in and have both block heather and charger powered. This keeps the battery warm and powered up for starting.Pros:Easy Installation: The installation process was a breeze. Thanks to its direct-mount design, I was able to install the NOCO GENIUS2D charger directly onto my car's battery. The package came with clear instructions, and the whole process took only a few minutes.Intelligent Charging: One of the standout features of this charger is its intelligence. The GENIUS2D is equipped with an advanced microprocessor that constantly monitors the battery's status and adapts the charging process accordingly. This ensures efficient charging, prevents overcharging, and helps extend the battery's lifespan.Multi-Stage Charging: The charger utilizes a multi-stage charging process, which is excellent for battery maintenance. It starts with a gentle trickle charge to bring the battery up to a suitable voltage, then switches to a bulk charge phase, and finally, a maintenance phase that keeps the battery at an optimal level.Versatility: While I primarily use it for my car, the GENIUS2D is also compatible with a wide range of other 12V lead-acid batteries, including marine batteries and deep-cycle batteries. This versatility is a huge plus, as it allows me to use it for other vehicles and equipment when needed.Durable Build: The charger's build quality feels solid and durable. The rugged construction ensures that it can withstand the rigors of daily use and various environmental conditions.Cons:As with any product, there are a few minor drawbacks to consider:Charging Speed: The NOCO GENIUS2D has a charging rate of 2 amps, which is sufficient for maintenance charging and ensuring the battery stays topped up. However, if you need to recharge a fully depleted battery quickly, you might need a charger with a higher amperage.Mounting Location: While the direct-mount design is convenient, it might not be suitable for all vehicle types. Depending on the battery's location and the car's design, mounting it directly might be a challenge.Conclusion:The NOCO GENIUS2D 2A Direct-Mount Intelligent Onboard Battery Charger has proven to be a reliable and efficient tool for keeping my car's battery in optimal condition. Its intelligent charging capabilities, ease of installation, and overall performance make it an excellent choice for any car owner looking to extend the life of their 12V battery. Despite its slightly lower charging speed, the benefits it offers in battery maintenance far outweigh this minor limitation. I highly recommend the GENIUS2D for its top-notch quality and peace of mind it provides when it comes to the health of your vehicle's battery.
