Charging the smart device SPRINT 4 automatic. Revive a dead battery of a car, and, if necessary, will support the level of battery charge! All that is required is to select the voltage corresponding to the battery voltage, turn on devices and connect the 'crocodiles.' Built-in microprocessor will do the rest. The device itself monitors the process and protects the battery from overcurrent. Specifications: - charging Current: 2-4 A; - power consumption: 75 W; Voltage: 6/12 V; - battery Capacity in charging mode: (6V)1.2-30/(12V)1.2-60 A/h; - battery Capacity in maintenance mode : (6V)1.2-60/(12V)1.2-120 A/h; - charging Mode: Automatic; Weight: 1 kg Fully automatic 7-stage charging maintains battery in excellent condition retaining all performance characteristics: 1. Primary diagnosis of the battery 2. Desulfatace. Eliminates sulfation of the plates of the battery. 3. A smooth start. Tests the ability of batteries to hold a charge. 4. The main charging. Up to 90% battery capacity in several phases to preserve maximum performance of the battery and extend its life. 5. Absorption. The charging current decreases smoothly to 100% battery capacity. 6. Leisure and diagnosis the ability of the battery to hold a charge. 7. The transition in the buffer mode to maintain full charge. Features: - microprocessor controlled fully automatic charging - several degrees of protection: reverse polarity, overcurrent, thermal protection, protection against sparks, overcharge protection battery high charging efficiency, maximum respect to the battery. All chargers Aurora can work with any type of battery, serviced with lead acid (WET) batteries and accumulators are not accepted from the gel (GEL) or solid electrolyte (AGM). Intelligent charger SPRINT can 'revive' deeply discharged batteries with a voltage of 1.5 V. If the battery produces less voltage, the device identifies the battery as working.
