CTEK56-158---CTEK Multi US 3300 Battery Charger for all 12V Lead-Acid Batteries (0.8Amp/3.3Amp)

 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 allow you to damage your vehicle's electrical system, even if you hook them up backwards.

The MULTI US 3300 charger works with most 12-volt batteries found in motorcycles, cars, SUVs, and small boats. It features a low-temperature mode that ensures 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.

The MULTI US 3300 uses a patented 3-stage cycle of energizing your battery, filling it with power, and maintaining its charge — this cycle repeats itself when 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.
