The G3500 is a smart, 8 Step, fully automatic switch-mode battery charger and maintainer. The G3500 restores batteries to their original capacity, recovers slightly sulfated batteries, charges batteries in cold climates, rescues drained batteries, and provides maintenance charging to increase battery life. A versatile battery charger that provides charging modes for both large and small batteries from 1.2-120Ah, such as Cars, RVs, Boats and Trucks, as well as for Motorcycles, ATVs, Jet Skis or Snowmobiles.
Powered by NOCO's VosFX Processor. This is a revolutionary smart processor utilizing sophisticated levels of intelligence to alter the charge process based on the organic feedback from the battery to extend battery life. The VosFX Processor quickly and efficiently makes decisions on how to charge the battery without risking user safety or damage to the battery.

Step 1: Diagnostics - Checks the battery voltage to make sure battery connections are good and the battery is in a stable condition before beginning the charge process.
Step 2: Recovery - Initializes the Recovery process, if needed, for deeply discharged or sulfated (desulfation) batteries by pulsing small amounts of current.
Step 3: Soft Start - Begins Bulk charging process with a gentle (soft) charge.
Step 4-5: Bulk - The Bulk charging process continues using both a High Rate and Medium Rate charge and returns 80% ofbattery capacity, indicated by the 25%, 50% and 75% CHARGE LEDs.
Step 6: Absorption - Brings the charge level to 90%. The battery charger will deliver small amounts of current to provide a safe, efficient charge and limit battery gassing.
Step 7: Trickle - Battery is fully charged and ready to use, indicated by the 100% CHARGE LED being a solid Green. In this step, the battery charger will only deliver enough current to keep the battery full. If the battery tells the charger that more current is needed, the battery charger will switch to Maintenance.
Step 8: Maintenance - Continuously monitors the battery voltage to determine if a maintenance charge should be initiated. If the terminal voltage falls below 6.4V (6V) and 12.8V (12V), the charger will start the Maintenance cycle until voltage reaches 7.2V (6V) and 14.4V (12V) and then discontinues the charge cycle. The cycle between Trickle and Maintenance is repeated indefinitely to keep the battery at full charge, without overcharging. The battery charger can be left connected indefinitely.
great product, fast shipping.
Needed this to keep batteries in my vehicles topped up after reading abou how short trips drain them over time and your alternator can't catch up. This did a fantastic job. It's small, has several progress lights that you can see from a distance and is supposedly "smart" so as not to overcharge the battery. On top of that I got the charger in about three days after making the order.

The Best Charger Out There By Far
Honestly I didn't buy this from Revzilla. I bought mine before Revzilla carried them otherwise I would have since I buy everything I can from Revzilla. As it is, I paid full price and waited a week to get mine. However this is such a good product I feel very motivated to share my enthusiasm for this charger. That I know of there is nothing on the market like this at any price. It is very sophisticated and I was able to bring an absolutely dead battery (that would not take a charge with a Battery Tender) back life. It so good that rumor is, and I believe it, this battery charger will enable you make motorcycle batteries last easily double what they would with another motorcycle battery charger.
The only drawbacks to this uint is that it is slow to charge. We are talking hours or on a weak battery maybe overnight. The other thing I don't like is that it does not have an On/Off switch. You have to unplug it to shut it off.
Other than that this is smart charger at the Genius level in every other way.

This charger does everything it promised. It's easy to use and easy to store. As always Revzilla delivered.

Bought this charger to use over the winter months on my 2013 ZX6R. Although I had to use it a couple of times on my car batteries. It works great so far.

One of the best chargers ever!
Bought this for my BMW with a GEL battery and it works like a charm... easy to use, excellent quality and design. The only thing I wish they would offer is a CanBus adapter.

Andrew L: My HD battery maintainer seemed not to be holding my battery at full charge. I would go on a long ride and battery was at 100% I then plug in the HD maintainer and the next day it would barley turn over to start. If I left bike sit for a day or two without the HD maintainer plugged in, the bike would turnover strong and start immediately.Oct 25, 2014
Daniel C: Great charger, like it a lot better than the competition.Sep 23, 2014
A shopper asked:Are additional compatible plugs available, ie to attach to a set of jumper cables so the battery doesn't need to be accessed if the battery needs to be jumped? Will the plug for the included clamps plug into the battery pigtail?Oct 29, 2013
