CTEK battery chargers aren't just boosters: they charge and maintain batteries with a patented system that's battery- and electronics-friendly. CTEK designed these elegant, compact chargers to be water- and shock-resistant, and they're UL-approved for outside use and immune to power line fluctuations. Your batteries will be charged efficiently with no interruption in their charging cycles. CTEK chargers' safety systems feature sparkless connections that won't damage your vehicle's electrical system, even if you hook them up backwards.

The MULTI US 7002 charger offers advanced charging and life-prolonging care for most heavy-duty 12-volt batteries found in cars, trucks, tractors, and boats — and CTEK stands by the 7002 with a 5-year warranty. CTEK's patented desulfation mode revives sulfated batteries after first determining if the battery can hold a charge — if not, the MULTI US 7002 will indicate the battery is faulty and requires replacement.

The 7002's Recondition mode can restore power to many discharged batteries, while Supply mode allows you to provide 12-volt power even when the battery is disconnected. Low-temperature mode ensures that your battery will get charged, and will maintain its charge, no matter what the weather.

Maintenance charging prolongs the lifetime of your battery by preventing complete discharge and acid buildup — perfect for motorcycles, snowmobiles, boats, campers, and other recreational vehicles that only get used seasonally, or for "must-start" equipment like snow plows and tractors. You can leave the MULTI US 7002 connected for months with no adverse affects on battery life or performance.

The MULTI US 7002 employs a unique 8-stage cycle of analyzing your battery, filling it with power, and maintaining its charge — this cycle repeats itself whenever the battery's voltage drops too low. And never fear for your audio equipment or other electronics; CTEK battery chargers are completely safe to use without having to disconnect your system.
