The NOCO Genius G3500 impresses with the packaging and the quality of the device, manual, cables and connectors. The controls and indicators are very clear and this looks to be a great product. Great product!!

The NOCO Genius G3500 uses an advanced eight-step process to charge and maintain your battery. First, it checks your battery’s voltage to make sure that the connections is good and that the battery is in stable condition before beginning the charge process. Second, it initializes a recovery process, if needed, for deeply discharged or sulfated batteries by pulsing small amounts of current. Next, it begins a bulk-charging process with a gentle (soft) charge. The process then continues using both a high-rate and medium-rate charge returns 80 percent of the battery’s capacity.

The user manual is very informative and easy to follow so that you will be able to quickly make use of the charger soon after you get it in the mail.

From there, the G3500 Genius brings the charge level to 100 percent and continues to deliver only enough current to keep the battery full. Finally, it monitors the battery voltage to determine whether a maintenance charge should be initiated. The maintenance cycle is repeated to keep the battery at full charge, without overcharging, and the charger can be left connected indefinitely.

Perhaps you have a lot of batteries that need to be charged or topped off during the year. You can use it on ATV, lawn mower and travel trailer deep cycle battery. No matter what, it will do a good job on topping off your batteries.

The ease of use and built in safety features allows you to hook it up and walk away knowing whenever you return to check on the battery you will find it charged and ready to go.

This charger runs ICE cold !!! It does not get hot like most other chargers.

This charger is light weight, especially if you are used to carrying out a thing the size and weight of a battery, to charge, a battery! It’s very light, has lots of things to tell you what’s going on with the battery, and tells you an indication of the charge.

These things are just more than what you can read about. To say the least these truly are very smart chargers. They also do really charge faster than any other charger you have ever used.


I highly recommend this charger to anyone who is tired of wasting money on chargers that fail or damage motor vehicle batteries. It is suitable for any type of battery.

This is a great product at an extraordinary price. A+
