CTEK Multi US 7000 Battery Charger 7-Step Charging, Reconditioning & Maintenance - and a Power Source The "powerhouse" of battery chargers, the CTEK MULTI US 7000, with a thorough 7-step process for maintenance and charging, is well-suited for year-round use with just about any vehicle. A special "recon" mode reconditions a drained battery after deep discharging, allowing the battery to recover more quickly and last longer. The CTEK MULTI US 7000 also functions as a power source, enabling in-place recharging of batteries without loss of power to the vehicle - maintaining the memory of the vehicle electronics. The latest addition to the CTEK lineup of "the smartest battery chargers in the world", the Multi US 7000 is not only suitable for automobiles and smaller recreation equipment, but also ideal for leisure, starter and marine batteries, as well as RVs and heavy trucks. Using Switch Mode Technology, the Multi US 7000 utilizes a 7-cycle intelligent process for exceptional battery maintenance and charging. Switch Mode "Intelligent" Technology Desulfation: Recovers or "wakes" a sulfated or under-charged battery. Soft Start: Tests the battery condition. Bulk Charge: Begins charging at 7A. Absorption: Applies peak charge at 14.4/14.7V until fully charged. Recondition: Reconditioning of drained battery. Float: Float charge applied for maintenance of maximum performance. Pulse: Sends out current pulses for charge maintenance. The Multi US 7000 is essentially foolproof to connect, wherever the battery is located. Unlike many competitive battery chargers, the Multi US 7000 has a patented protection system against sparks, short circuits and reverse polarity, virtually eliminating any fear or apprehension about charging a battery. The Multi US 7000 is approved for outdoor use in all types of weather and is a Five step, fully automatic (IIUoIUp) switch mode battery charger for all 12V lead-acid batteries.
