• motorcycles
• ATVs
• jet skis
• snowmobiles

This battery charger has an 8 charging modes. They are as follows:

• 6V Norm LED - for 6V wet, gel and MF batteries (14-120ah)
• 6V Cold / AGM LED - for 6V batteries below 32 degrees Fahrenheit and AGM batteries(14-120Ah)
• 12V Norm LED - for 12V west, gel and MF batteries(14-120Ah)
• 12V Cold / AGM LED - for 12V batteries below 32 degrees Fahrenheit and AGM batteries(14-120Ah)
• 6V Small Norm LED - for 6V wet, gel and MF batteries (1.2-14Ah)
• 6V Small Cold / AGM LED - for 6V batteries below 32 degrees Fahrenheit (1.2-14Ah)
• 12V Small Norm LED - for 12V wet, gel and MF batteries (1.2-14Ah)
• 12V Small Cold / AGM LED - for 12V batteries below 32 degrees Fahrenheit (1.2-14Ah)

Simple User Interface

Mode Button to select the charging modes manually.
Error LED illuminates when reverse polarity or another problem is present.
Charge level reveals the current charge level of the battery.
Standby LED is lit when a charging mode has not been selected.

The G3500 comes with 

Comfort Cable Clamps

Designed to make it easy to connect and disconnect your battery. Has a fully insulated over-mold casing with strain relief ends to alleviate unwanted tension on cable leads.




Built-In Fuse Protection

Features an over-molded inline fuse to increase user safety by protecting the battery charger from potentially dangerous short circuits. 

Extendable Connectors

Uniquely designed interchangeable connector allows accessories to be properly mated and fastened with a snap-lock latch.



Rugged Enclosure

Made from a rugged polymer for high-impact resistance for some of the harshest and most demanding working environments. 


NOCO VosFX Processor - this is what makes this product so wicked smart. This processor uses sophisticated levels of intelligence to alter the charge process based on organic feedback from the battery to extend battery life. It quickly and efficiently makes decisions on how to charge the battery without risking user safety or damage to the battery.

CHARGING TIMES

The time required for the G3500 to charge a normally discharged battery is shown below. Deeply discharged batteries may take longer to charge depending n the dept 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%.

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.
