About G3500.The NOCO Genius®G3500 represents
some of the most innovative and advanced technology
on the market, making each charge simple and easy. It is
quite possibly the safest and most efcient charger you
will ever use. The G3500 is designed for charging all types
of 12V lead-acid and 12V lithium-ion batteries, including
Wet (Flooded), Gel, MF (Maintenance-Free), CA (Calcium),
EFB (Enhanced Flooded Battery), AGM (Absorption Glass
Mat), and LIB (Lithium Ion) batteries. It is suitable for
charging battery capacities from 2 to 120 Amp-Hours and
maintaining all battery sizes.
Getting Started. Before using the charger, carefully
read the battery manufacturer’s specic precautions and
recommended rates of charge for the battery. Make sure
to determine the voltage and chemistry of the battery by
referring to your battery owner’s manual prior to charging.
Mounting.The G3500 has four (4) external holes for
mounting. Mount the charger in a desired location with
#6 self-drill screws. Make sure there are no obstructions
behind the mounting surface. It is important to keep in mind
the distance to the battery. The DC cable length from the
charger, with either the battery clamp or eyelet terminal
connectors, is approximately 75-inches (1,900mm). Allow
for 12-inches (304mm) of slack between connections.
Charging Modes. The G3500 has eight (8) modes:
Standby, 12V NORM, 12V COLD/AGM, 12V NORM [Small],
12V COLD/AGM [Small], 6V NORM, 12V LITHIUM, and 12V
REPAIR. Some charge modes must be pressed and held
for three (3) seconds to enter the mode. These “Press and
Hold” modes are advanced charging modes that require
your full attention before selecting. “Press and Hold” are

to understand the differences and purpose of each
charge mode. Do not operate the charger until you
conrm the appropriate charge mode for your battery.

In Standby mode, the charger is not
charging or providing any power to
the battery. Energy Save is activated
during this mode, drawing microscopic
power from the electrical outlet. When
selected, an orange LED will illuminate.

a white LED will illuminate.
For charging 12-volt batteries in cold

Using 6V NORM. [Press & Hold]
6V NORM charge mode is designed for 6-volt lead-acid
batteries only, like Wet Cell, Gel Cell, Enhanced Flooded,
Maintenance-Free and Calcium batteries. Consult the
battery manufacturer before using this mode.
CAUTION. THIS MODE IS FOR 6-VOLT LEAD-ACID
BATTERIES ONLY.
Using 12V Lithium. [Press & Hold]
12V Lithium charge mode is designed for 12-volt lithium-ion
batteries only, including lithium iron phosphate.
CAUTION. USE THIS MODE WITH CARE. THIS MODE
IS FOR 12-VOLT LITHIUM BATTERIES ONLY. LITHIUM-
ION BATTERIES ARE MADE AND CONSTRUCTED
IN DIFFERENT WAYS AND SOME MAY OR MAY NOT
CONTAIN A BATTERY MANAGEMENT SYSTEM (BMS).

Using 12V Repair. [Press & Hold]
12V Repair is an advanced battery recovery mode for
repairing and storing, old, idle, damaged, stratied or
sulfated batteries. Not all batteries can be recovered.
Batteries tend to become damaged if kept at a low
charge and/or never given the opportunity to receive
a full charge. The most common battery problems
are battery sulfation and stratication. Both battery
sulfation and stratication will articially raise the open
circuit voltage of the battery, causing the battery to
appear fully charged, while providing low capacity. Use
12V Repair in attempt to reverse these problems. For
optimal results, take the 12-volt battery through a full
charge cycle, bringing the battery to full charge, before
using this mode. 12V Repair can take up to four (4)
hours to complete the recovery process and will return
to Standby when completed.
CAUTION. USE THIS MODE WITH CARE. THIS
MODE IS FOR 12-VOLT LEAD-ACID BATTERIES ONLY.
THIS MODE USES A HIGH CHARGING VOLTAGE
AND MAY CAUSE SOME WATER LOSS IN WET
(FLOODED) CELL BATTERIES. BE ADVISED, SOME
BATTERIES AND ELECTRONICS MAY BE SENSITIVE
TO HIGH CHARGING VOLTAGES. TO MINIMIZE RISKS
TO ELECTRONICS, DISCONNECT THE BATTERY
BEFORE USING THIS MODE.
Connecting to the Battery.
Do not connect the AC power plug until all other
connections are made. Identify the correct polarity of
the battery terminals on the battery. The positive battery
terminal is typically marked by these letters or symbol
(POS,P,+). The negative battery terminal is typically
marked by these letters or symbol (NEG,N,-). Do not
make any connections to the carburetor, fuel lines, or
thin, sheet metal parts. The below instructions are for a
negative ground system (most common). If your vehicle
is a positive ground system (very uncommon), follow
the below instructions in reverse order.
