Corvette CTEK Battery Charger US3300

Ok Vette fans or any other car nut (works great on all cars and trucks), we are coming into winter and most of us will have the Vette in the Garage more than we will on the street. Do yourself a favor and check out the cool little battery charger from Ctek. I have been using it for the last couple weeks, and it is hands down the coolest battery charger I have ever seen. Small, efficient and smart. Just hook it up and go..It takes care of your Corvette's battery all winter long.

Don't let your Corvette battery drain out all winter long. Get a smart charger that contstantly monitors your batteries charged and keeps it at optimum charge throughout the winter months. This is most likely the smallest Corvette Batter charger on the market and has gotten rave reviews from Dream Car Garage.


The CTEK Multi US 3300 is a strong multi-tasker that can handle but the largest vehicles. Particularly well-suited for Corvette (all models) use, the Multi US 3300 offers outstanding recharging performance- the car is back on the road typically in under an hour. A unique cold tempature mode enable faster recharging, even in the coldest winter conditions. The CTEK Multi US 3300 is specifically recommended for Optima Red Top Batteries. The smartest battery charger in the world uses a four step charge process: Desulfation, Bulk Charge, Absorption and Pulse. This charger is virtually the only charger needed to keep 12V lead-acid batteries charged up and ready for anything. Compact, lightweight and portable, CTEK also protects users against sparks, short circuits and reverse polarity.




Features of the CTEK Charge include

Switch-Mode technology Simply put, our chargers quite technically advanced and incorporate state of the art electronics to produce an extremely energy efficient and powerful lead acid battery charger and maintainer.  A result of the new multi-patented technology break-throughs is apparent in the design of CTEK chargers.  They are small, compact, easily transported and stored, shock resistant and quite powerful. In terms of size and portability, they have shattered the perceptions previously associated with battery chargers incorporating traditional transformer- type designs. 

Reverse polarity protection
Accidentally switching the positive/negative  battery charger leads to the incorrect battery terminal posts  will result in a red LED signal on our charger indicating they not properly attached.

Line Surge Suppression. 
Erratic voltage line surges are suppressed--thereby minimizing the risk of crippling line voltage spikes and the subsequent damage to sensitive equipment such as computer chips, stereo equipment or other componentry.  Our chargers have been successfully tested at 4000 volts.

Built in timers
Built in timers to prevent the continual charging of a shorted or severely discharged battery.

A reliable sealed design:

Our design allows for one durable, shock resistant, vibration resistant tough charger! Mount it inside your ride, and attach it permanently!  Use the quick disconnects for easy hassle- free and SIMPLE hoop up in your garage!

Water resistant cover, with APPROVAL for outdoor use, even in cold weather!

Compact, lightweight construction for easy storage and portability 
Many models will fit in automobile glove box If you are an “on the go” individual who prefers to travel light while still maintaining your Toys—CTEK chargers are the way to go. Take CTEK charging convenience with you; leave the cumbersome and bulky chargers behind.

Constant Current Charging
Nearly ripple free, CTEK Chargers provide nearly pure DC current with less than 5% current ripple.  

Desulphation stage 
Sulfated battery’s are difficult to charge.  Our patent-- pending desulphation mode can help break through a badly sulphated battery to allow it to accept charging. The desulphation stage monitors the battery’s ability to start accepting a charge effectively by applying a very low charge current at a regulated voltage.  It will initially pulse at a rate of 10 times per second.  As the battery starts to initially accept a charge, the pulses slow down and then allow the charger to the next stage.  

Pulse stage
Most conventional trickle chargers continue to charge without shutting off.   The CTEK chargers completely shut off the current and voltage until the battery falls to a 12.9 voltage level.  It will restart for a short duration at a minimal current level until the battery reaches the chargers regulation level.  This process continues until the charger is disconnected.
