For a cutting-edge battery charger and jump starter trusted by professionals, look no further than Schumacher’s line of ultracap battery chargers and starters. Schumacher’s 12-Volt Ultracap Battery Charger and Portable Jump Starter features the latest ultracapacitor technology and an internal lithium battery, giving professional mechanics the option of taking the unit out of the shop to jump a vehicle. The Schumacher 12-Volt Ultracap Battery Charger and Portable Jump Starter also features high power density, quick charging, added cranking power and superior reliability with its dual ultracap/lithium design. Ultracap technology delivers several advantages over traditional AGM and lithium jump starters. Incorporating ultracaps extends the lifespan of the jump starter. The SC1591’s ultracaps are rated for more than 10,000 cycles, while AGM and lithium jump starters usually are rated for under 1,000 cycles. In addition, ultracaps, unlike lithium batteries, can be fully discharged without damage. Moreover, ultracaps can be fully recharged in only few minutes, while recharging a lithium battery can take 2-hours to 4-hours. Ultracaps also deliver superior performance in extreme conditions, outperforming lithium and AGM jump starters and offering reliable starting at temperatures as low as minus 40°F or as high as 140°F.
