It's a charger... It's a battery fixer... It's a CTEK!

Three-selectable modes for different battery needs

Fully automatic 8-step charging and maintenance

Safely works in all weather conditions and situations

The CTEK Multi US 4.3 12 Volt Charger is the highly intelligent battery charger that provides professional-quality results. Much more than a battery charger, the CTEK Multi US 4.3 12 Volt Charger utilizes state of the art technology once reserved for their professional product range. It is capable of diagnosing, repairing, and preventing a large number of battery-related problems. You may think something this smart should be piloting a spacecraft and could be difficult to use – its not. Attach the CTEK Multi US 4.3 12 Volt Charger to your battery like any charger and let its intelligence do the work for you!

The CTEK Multi US 4.3 12 Volt Charger first tests your battery to determine if it can hold a charge. A special reconditioning function restores stratified and deeply discharged batteries. It features a fully automatic 8-step charging process that delivers a selectable .8 amps or 4.3 amps to 12 V batteries from 1.2-110 amps/hour (Ah). The CTEK Multi US 4.3 12 Volt Charger is suitable for charging up to 160 Ah.

The CTEK Multi US 4.3 12 Volt Charger features multiple modes making it the only charger you will need to charge your car, motorcycle, snowmobile, sump pump and tractor. It even features a special winter mode that is ideal for charging and maintaining high-demand batteries in winter's coldest months.

Like all CTEK products, the Multi US 4.3 is built to last. 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 4.3 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 4.3 12 Volt Charger comes with a 5-year warranty to protect your piece of mind as well as the charger protects your battery.
