CTEK MULTI US 3300 is a strong multi-tasker that can handle all but
the largest vehicles. Particularly well suited for automotive use, the
MULTI US 3300 offers outstanding recharging performance - the car is
back on the road typically in under an hour. A unique cold temperature
mode enables faster recharging, even in the coldest winter conditions.
The Multi US 3300 utilizes Switch Mode Technology, a 4-cycle intelligent process for perfect battery maintenance and charging
Switch Mode "Intelligent" Technology
Desulfation: Recovers or "wakes" a sulfated or under-charged battery.
Bulk Charge: Begins charging at 0.8/3.3A.
Absorption: Applies peak charge at 14.4/14.7V until fully charged.
Pulse: Sends out current pulses for charge maintenance.
As compared to competitive battery chargers, the Multi US 3300 is
virtually foolproof to connect, wherever the battery is located. The
Multi US 3300 essentially eliminates any fear or apprehension about
charging a battery because of its patented protection system against
sparks, short circuits and reverse polarity. Approved for outdoor use,
the charger can be used in any weather conditions. Three step, fully
