The Multi US 3300 charges and maintains all 12 volt batteries including: motorcycles, snowmobiles, jet skis, power sports toys, cars, classic cars, trucks, forklifts, and boats. This is the "World's smartest battery charger" that only gives your battery as much juice as it needs, no boiling or overheating. The Multi US 3300 can replace your large "shop charger" and has three different automatic Mode cycles including one dedicated to charging Optima Red Top batteries (batteries with spiral cell technology). The 3300 is our most popular charger and can handle all your needs.The US 800 is great for maintaining a cars battery but cannot charge a flat battery as fast as the 3300 or 7000. The CTEK switched mode charger does this with very low heat and is built into a very compact, weather resistant and dust proof housing.
