NOCO Genius G3500 Battery Charger
Batteries need to be maintained. Your trailer's battery should always be hooked up to a smart charge source, especially if you aren't using your trailer for long periods of time. The NOCO G3500 is a sophisticated 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.
In addition, it is a highly versatile battery charger that provides charging modes for both large and small batteries from 1.2-120Ah. Not only does it work great on your trailer battery, it is perfect for cars, trucks, boats and even motorcycles, ATVs, Jet Skis and snowmobiles!
Here's how the 8-step system works...
Checks the battery voltage to make sure battery connections are good and the battery is in a stable condition before beginning the charge process.
Initializes the Recovery process, if needed, for deeply discharged or sulfated (desulfation) batteries by pulsing small amounts of current.
Begins Bulk charging process with a gentle (soft) charge.
The Bulk charging process continues using both a High Rate and Medium Rate charge and returns 80% of battery capacity, indicated by the 25%, 50% and 75% CHARGE LEDs.
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.
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.
Continuously monitors the battery voltage to determine if a maintenance charge should be initiated. If the terminal voltage falls below 12.8V (or 6.4V on 6V batteries), the charger will start the Maintenance cycle until voltage reaches 14.4V (or 7.2V on 6V batteries) 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.
The time required for the G3500 to charge a normally discharged battery is shown below. Deeply discharged batteries may take longer to charge depending on the depth of discharge (DOD). The charge time is based on an average depth of discharge to a fully charged battery.
Note: The above table is for reference purposes only. Actual data may differ due to battery conditions. The time required for the G3500 to charge a normally discharged battery is based on an average DOD of 50%.
