CTEK Multi US 3300 Battery Charger
Keep yourself prepared at all times with this CTEK Multi US 3300 battery charger! This versatile battery charger can charge your Mustang, Ford Lightning, boat, or even your lawn mower! Any battery with up to 120Ah is compatible with this charger. Simply connect the charger to the battery, select your mode, and plug it in! With this battery charger, there's no knowledge of batteries or charging methods needed. The charger will take it's own readings, charge the battery, and then automatically switch modes when finished!
Three Mode Choices
The versatility of this charger allows you to select three different modes, depending on what you're charging. The low current mode is perfect for smaller 12V batteries such as motorcycles, lawn mowers, and jet skies. The higher current mode is great for automotive or marine applications with larger batteries. The third and final mode is the winter mode. This allows you charge and maintain your batteries in cold weather down to -4 degrees!
A patented desulphation function allows this charger to recondition sulfated batteries. An unused battery can lose it's power and life though a process called sulphation. This charger will analyze the state of the battery and, if possible, will recover the battery and it's power.

**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.
