[The Newest Arrival of 2022]: With a new industrial design that is more compact, more attractive, and simpler to use than your average car battery charger, Sigma 1 stands out from the crowd. Best of all, it is not only a battery charger, but also a battery maintainer, trickel/floating charger, and battery desulfator. Combined with its pure copper clamp, Sigma 1 offers customers the best charging experience ever.
[Smartest Charger Ever]: HULKMAN’s smartest car battery charger yet, the Sigma 1 is built with next-level intelligence. Using its nine-step charging technology, Sigma 1 can now maintain your battery overnight or for an even longer period, with zero attention needed and complete dependability, creating a totally hands-free charging experience.
[Read With Ease]: Once you plug in and attach the battery, a huge 2.7-inch LED screen intuitively indicates the battery level, voltage, and charging mode. Simply select a charging mode and it will begin delivering the power to your battery, making your charge easier and better than ever before.
[Save Dead Batteries]: If your battery has died, you can now charge dead batteries with our “Advanced Loading Mode,” a scientific charging process that delivers significant current power through qualification, soft start, and pulse mode, as well as recondition and bulk stages, to stimulate dead batteries back to life.
[One For All]: This charger is compatible with either 6V or 12V sealed lead-acid, and 12V lithium-ion batteries, including deep-cycle, AGM, lifepo4, flooded, gel, wet, maintenance-free, EFB, and calcium batteries.
[Super Repair Mode]: This car battery charger can accurately recognize bad batteries. By implementing the 12V “Super Repair Mode,” you can enhance your battery performance in only four hours and avoid purchasing an unnecessary replacement by reducing sulfation build-up and acid stratification with pulse cycles, thus offering you a cost-effective, money-saving, and environmentally friendly battery solution.
[More Versatile]: Sigma 1 allows you to charge and maintain most gas and diesel vehicles such as automotives, motorcycles, scooters, ATVs, RVs, powersport vehicles, lawn mowers, marine vehicles, and more.
