Features of Noco GENIUS2D Battery Charger

Ease of Use 

Instructions are not easy to read and understand, but once you figure out how to use Noco GENIUS10 Battery Charger, you won’t have any other problems with its usage. It will be an excellent convenience for you. Since it is automatic, it can automatically detect problems and repair the battery if there is a problem. You can see the battery problems from the digital display.

The digital display shows the remaining battery beside the bad battery condition. You can check the percentage of the battery from this panel. You can easily charge it with its x-connect battery connectors. It provides a quicker connection. So you don’t have to deal with too much. Also, you do not need to worry about using it in different temperatures because the digital thermal sensor adjusts the charging according to the temperature. 

One of the best features of this product is that overcharging is not possible. You can charge it as much as you want; it will automatically stop when fully charged. This prevents you from wasting your time. In addition, while your battery is charging, you can do other things. It also has auto memory to remember the mode you have used before. But it only works well for 6V batteries. 


Although this product is smaller, it has 115% more power than other brand products. So, it is one of the products with the highest performance. It has a high performance, but it is also energy-efficient. It automatically detects battery sulfation, thus regenerating damaged batteries and conserving their power. It also automatically detects and charges when the battery is below 1 watt.

Its engine is more powerful than most others. In addition, you will not experience performance loss in hot and cold climates. It can accurately charge between -4 F and 104 F. It won’t overcharge or undercharge. It can even be used to improve overcharged batteries. In this respect, it will be more than a charger for you. It will give your batteries back their old performance.

It works very well on both small and large 12V batteries. However, charging 6V batteries may take a little more time. 6V large deep cycle batteries charge very slowly. Of course, this product is a fast charger and will be expected to charge as soon as possible. We can say that those with 12V batteries will charge a little faster. Exactly how many hours it will charge varies.

Review: The instructions are VERY hard to follow – because they made a lot of assumptions.

Review: I bought this unit to attempt to rejuvenate a bad 12 volt lead acid car battery. The battery is about 1-1/2 years old and is likely covered under warranty, but I wanted to try to determine why my batteries are failing so often. The first problem is that I have two vehicles that get driven less than once a month. The alarms, stereos, and onboard computers steadily drain the batteries even when not driven. From what I have read, this is the worst thing you can do to a car battery. Sources state that a sulfate coating develops on car batteries when there is a steady draw on power and the battery is allowed to drain down without being recharged on a regular basis. Main symptoms were low cranking amps and going dead one to two days after charging. One of the features of this unit is its “repair” mode which provides an electronic pulse cycle that is known to break down this sulfate coating and restore some of the batteries service life. While there are several failure modes to a battery that cannot be fixed by this method, this common abuse of a battery (infrequent driving) can often be reversed and restore some battery life. The results so far (I am still working on it) indicate I have restored the battery to about 75% of its new condition. The repair cycles are: 1) Charge the battery using this device, 2) Use the “repair” mode of this device to desulfate the battery, 3) Test the battery (using a battery tester I bought on Amazon), 4) Discharge the battery by attaching a headlight, 5) Repeat 1-4. Each time I repeat the cycles (3 times so far) the battery’s condition improves. I understand I will not be able to restore the battery to a new condition, but it appears to be able to return to service at this point. I give this a 5 start rating due to 1) The manual, while brief, is well written (a rarity) and contains the basic information needed, 2) The charging cycle works very well and should protect the battery from overcharging, 3) The device works on a number of different battery types, 4) It does everything (so far) that it claims it can.

Review: My car was parked for a few months without being driven, and the battery died. I have tried to jump start it successfully, but once turn it off again, battery was so drained I couldn’t turn it on again. As a last resort before changing the battery, I decided to give a shot to this item. It came fast and nicely packed, with cables long enough to make it easy to reach the closest outlet. I have to say I would love having more detailed instructions in the booklet, however it is not really hard to use it. It seems to be pretty safe as well, turning off immediately if the circuit is breaking for any reason (e.g., one of the clamps gets off). After connecting it and selecting the right voltage and chemistry of my battery, I let it work on the battery disconnected from the car for a few hours without any noticeable progress. Then I switched to repair mode, which is unclear how it works (because of the lack of detailed instructions), for a couple of hours. Got back to the normal charge mode, and surprisingly in a few seconds I’ve seen the charging lights going up to 75%! Kept going for a couple of more hours, till reaching the green light for a full charge. Reconnected the battery to the car, and it turned on like a charm! This little thing really made my day.
