The CTEK Multi US 3300 12 Volt Charger offers state of the art technology in combination with versatility to make this the ideal charger for multiple applications. With three separate selectable modes, the CTEK Multi US 3300 12 Volt Charger can efficiently charge smaller 12 V batteries such as those on motorcycles, full-sized 12 V batteries such as those on automobiles, and features an additional winter mode for charging and maintaining in cold weather.
In addition to the three battery charging modes, the CTEK Multi US 3300 12 Volt Charger features a water-resistant rugged construction that has been certified for use between -4 degrees F and +122 degrees F. Additionally the CTEK Multi US 3300 12 Volt Charger is compatible with sensitive modern electrical equipment.
The CTEK Multi US 3300 12 Volt Charger's selectable modes and rugged construction give you the flexibility to use it in a number of applications. The attractive packaging is dust proof and splash resistant. Additional built-in safety features include a non-sparking design and protection against reverse polarity, in addition to being shortcircuit proof. It even reverses sulfation to keep lead-acid batteries operating efficiently
Sulfation is a condition in which infrequently used lead-acid batteries lose their ability to accept and maintain a charge. This is a common occurrence in classic automobiles and rarely used equipment. The CTEK Multi US 3300 12 Volt Charger utilizes CTEK's patented desulphation function to protect lead-acid batteries from sulfation and conditions the battery through a specific pulse charge. The CTEK Multi US 3300 12 Volt Charger comes with a 5-year warranty to protect your piece of mind as well as the charger protects your battery.
