Pros trust Schumacher’s 12V Ultracap Battery Charger and Engine Starter to get the job done either in the shop or on the go. Featuring cutting-edge ultracap technology and an internal lithium battery, the SC1591 gives users the option of taking the unit out of the bay to jump a vehicle. Users will also enjoy high power density, quick charging, added cranking power, and superior reliability with this dual ultracap/lithium design. The unit’s ultracap portable jump starter features 800 peak amps for powerful jump starting and can be recharged from the internal lithium battery for additional jump starts.
Ultracaps deliver powerful advantages over traditional AGM and lithium jump starters. The SC1591’s ultracaps are rated for more than 10,000 cycles while AGM and lithium jump starters typically are rated for under 1,000 cycles. Ultracaps, unlike lithium batteries, will not be damaged if fully discharged and ultracaps can be fully recharged in a few minutes vs. two to four hours to charge a lithium battery. And in extreme conditions, ultracaps outperform lithium and AGM jump starters, providing superior starting at -40°F or 140°F.
In addition to portable jump-starting capabilities, when plugged into AC power the SC1591 features 500A engine start, 30A boost, and 6A charge. The 30A boost mode ramps up the voltage and sends a burst of energy into the battery to quickly bring deeply discharged batteries back to life.
Whether the unit is used in a home garage, a professional shop, or out on a call, the 12V Ultracap Battery Charger and Engine Starter will stand up to tough use thanks to its heavy-duty steel case and rugged metal clamps on 6-foot, 6-gauge cables. In addition, the unit’s digital display, LED indicators, and push-button controls make it easy to use and allow the operator accurate control.
