Noco 6v & 12v 3500ma switch-mode sla battery charger and maintainer g3500

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 SLA Batteries, Cars, RVs, Boats and Trucks, as well as for Motorcycles, ATVs, Jet Skis or Snowmobiles.

The time required for the G1100 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 G1100 to charge a normally discharged battery is based on an average DOD of 50%.
Charging Steps
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% of battery 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.
