Keep Your Batteries Charged and Maintained

With the NOCO G3500, you can restore batteries to their original capacity, recover slightly sulfated batteries, charge batteries in cold climates, rescue drained batteries, and give your battery maintenance charges. As a result, you can extend the life of your battery and improve its capacity. Different modes allow you to charge large batteries for cars, trucks, boats, and RVs as well as small batteries found in motorcycles, ATVs, jet skis, and snowmobiles.

Eight-Step Charging Process

The NOCO 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 are 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.

From there, the G3500 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.

Switch-Mode Design with Advanced Features

The NOCO G3500 features a high-frequency, high-efficiency switch-mode design, resulting in a charger that's compact and lightweight. An auto-memory function returns the charger to the last selected mode when you restart it. Thanks to NOCO's Rapid Charging Technology, the G3500 charges batteries two times faster than traditional linear battery chargers. With Abnormality Protection, the charger automatically shuts off if it's been left in bulk charge mode for an extended period of time. The charger is also designed to adjust automatically to changing current needs and prevent reverse polarity, short circuits, open circuits, sparks, overheating, over-currents, and overcharging. It also offers an optimized charge mode for cold weather or AGM batteries.

VosFX Processor for Smart Battery Charging

The NOCO G3500 comes equipped with a VosFX smart processor that alters the charge process based on organic feedback from the battery to extend the battery life. The processor quickly and efficiently makes decisions on how to charge the battery without risking your safety or damage to the battery.

The charger measures 1.9 by 7.7 by 2.7 inches (H x W x D) and weighs 1.1 pounds. It features a rugged polymer enclosure built for high-impact resistance--making the charger well suited for harsh or demanding work environments. Extendable, plug-and-play connectors allow you to change accessories easily.

The NOCO G3500 battery charger and maintainer is backed by a five-year limited warranty.

This review is from: NOCO Genius G3500 6V/12V 3.5A Automatic Multi-Purpose Battery Charger and Maintainer (Grey) (Automotive)
Never have I seen a better charger! I even bought the $500.00 garbage from Sears, this little guy however charges faster and I don't fear leaving it on as it does turn off by itself. If you buy this product, you won't regret it!

This review is from: NOCO Genius G3500 6V/12V 3.5A Automatic Multi-Purpose Battery Charger and Maintainer (Grey) (Automotive)
Just what I need to keep my car battery strong. I am into car audio and have to keep my battery fully charge to keep the load off my alternator. This Genius multi purpose charger is excellent for the type of AGM battery I have in my car.

5.0 out of 5 stars Nice charger, February 10, 2012
Amazon Verified Purchase(What's this?)
This review is from: NOCO Genius G3500 6V/12V 3.5A Automatic Multi-Purpose Battery Charger and Maintainer (Grey) (Automotive)
I have an AGM battery in my car and I wanted to make sure the charger I bought supports that type of battery. I`m really impressed with the Genius charger. The status lights let you know exactly what the charger is doing. I'd recommend the charger to anyone with AGM or Gel batteries (as well as traditional wet-cell batteries).

Amazon (as usual) had the best price and it was shipped in a timely manner.
