Quadratec Part No: 97004.1010 Manufacturer Part No: 56-158 $69.99
Practical all-round battery charger that every household should have.
The MULTI US 3300 is a versatile battery charger in a compact format that makes it convenient and easy to charge and maintain all household vehicles. The special cold mode means that you can also charge during cold winters days without problems. The MULTI US 3300 satisfies all the home’s battery charging needs as it charges all types of 12V batteries such as your car, motorcycle, lawnmower, jet ski, snowmobile, caravan or smaller size boats.
There is no need for any specific knowledge of
batteries or their charging methods; the MULTI
US 3300 will take care it. Once switched to the
prefered mode, the charger takes its own readings
and then begins to charge the battery. Once it is
finished charging, it will automatically switch to its
maintenance phase–CTEK’s patented pulse charging–
arguably the most caring mode for a battery
connected for a long time. Simply connect it to
solve most battery problems from the past.
Flexible for different
battery needs
The MULTI US 3300 is specifically developed for
different needs, vehicles and batteries. There is a
choice between three different modes. The low-current
mode (the motorcycle icon) is perfect for smaller
12V batteries such as motorbikes, lawnmowers,
jet skies, snowmobiles, etc. The higher current mode
(the car icon) is for automotive or marine applications
with larger batteries. Finally, an additional
winter mode (the snowflake) is specifically aimed
at charging and maintenance in cold weather. It is
also perfectly suited for Optima Red Top batteries.
Patented desulfation
function
Unused batteries lose their power and their life is
shortened through sulfation. It is also more difficult
to charge sulfated batteries. The MULTI US 3300
has a patented method for reconditioning sulfated
batteries. The charger analyzes the state of the battery
and, if possible, recovers the battery and its
power.
Compatible with other
electronic equipment
Most vehicles today are equipped with sensitive
electronic systems. Unlike less-sophisticated chargers,
there is no need to disconnect the battery;
the MULTI US 3300 is specially designed to not
damage electronic systems.
Made for all weather
conditions and situations
The MULTI US 3300 is prepared to charge and
maintain, no matter the weather, temperature or
situation. The MULTI US 3300 is extremely robust
and water and dust resistant (IP65 classification).
The MULTI US 3300 is certified for use between
–4şF and +122şF. In order to make things easier
and more convenient, the Comfort Connect (eyelet
terminals) can be permanently connected to the
vehicle’s battery.
Designed for safety
All CTEK models are designed to consider the
safety of the user. They are spark free, making the
connection much easier and safer considering the
gases batteries normally produce. The MULTI US
3300 is also protected from reverse-polarity connections
and is short-circuit proof. A red light on the
charger will simply indicate that the charging cannot
begin until the user has connected the charger
correctly.

*) Back current drain is what drains the battery if the charger is connected without the power cord connected.
**) Ripple describes the quality of the current and voltage. A high current ripple heats the battery and shortens its life. A linear charger has a current ripple of
70–400% which is much larger than the maximum 5% for a modern sealed battery. High voltage ripple could harm other equipment that is connected to the battery.
MULTI US 3300 delivers voltage and current with very low ripple. The battery has a long service life and there is no risk of damage to other electronic devices connected to the battery.
