About G3500.

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
