Description Battery Charger Topdon T4000C 6V/12V 4A Topdon T4000C 6V & 12V 4A Battery Charger TOPDON T4000C Smart Battery Charger & Maintainer 6V/12V 4A The Tornado4000 is more than just a smart, compact battery charger. It is a battery maintainer, charger, desulfator, and DC power supply all in one unit. The Tornado4000 provides a stable 13.5V DC output to power devices on a boat, with a capacity of up to 4A. It is compatible with 6V/12V lead-acid batteries and 12V lithium-ion batteries up to 120Ah. The 5 charging modes combined with the 9-step smart charging technology make the Tornado4000 extremely versatile. Thanks to its IP65 waterproof casing and the ability to operate in cold weather conditions (down to -20°C / -4°F), it can be used in various environments while remaining lightweight and portable. Its operation is easy, with four clear error indicators. Broad Charging Capabilities Supports Multiple Battery Types The Tornado4000 supports a wide range of batteries, from 5Ah to 120Ah, compatible with all types of 6V & 12V lead-acid batteries and 12V lithium-ion batteries, including LI, AGM, WET, GEL, MF, CAL, and EFB. 5 Charging Modes The Tornado4000 offers 5 charging modes: 12V NORM, 12V LI, 12V REP, 12V SUP, and 6V NORM. Simply select the appropriate charging mode for your battery and let the Tornado4000 do the rest. Stable Power Supply and Voltage Stabilizer Providing a 13.5V output and a maximum current of 4A (54W), the Tornado4000 works as a voltage stabilizer for ECU programming and a power supply for 12V devices such as tire inflation units, lamps, fans, etc., with the “SUPPLY” 12V mode. Battery Desulfation Capabilities Using pulse width modulation to break down sulfate crystals in an aging battery, the Tornado4000 can effectively restore battery resistance and extend its lifespan by rejuvenating the battery and returning it to optimal working condition. Self-Regulating Power Supply with Safety in Mind As a safety measure, the Tornado4000 automatically adjusts the charging power based on various conditions, such as the temperature of the charger or the surrounding environment. 9-Step Smart Charging Mode TOPDON’s patented 9-step smart charging technology provides your lead-acid battery with an optimized, maintained, and complete charging process. When connected, the Tornado4000 not only charges the battery but also acts as a battery maintainer to truly repair your car’s battery. Additionally, the Tornado4000 specializes in providing a 5-step smart charging mode for lithium batteries. One-Touch Charging and Memory Function Once a charging mode is selected, the Tornado4000 will begin charging automatically without needing any further adjustments. The charger also features a memory function that will continue charging in the previously set charging mode when the charger is turned back on after being powered off. Four Clear Error Indicators Equipped with four error indicators, the Tornado4000 not only displays the detected voltage of the device but also clearly shows the charging status. Reverse Connection/Short Circuit Faulty Battery: Battery voltage unusually high Charging Time Overrun: > 10 hours in one stage Overheating: > 120°C / 248°F Smart Safety Inside and Out Internal Safety The Tornado4000 is equipped with built-in safety systems for overheating, short circuits, overvoltage, reverse connection, and sparks. External Safety With an IP65 protection rating and constructed from ABS outer casing, the Tornado4000 is dust and water-resistant. It is also flame retardant and can withstand temperatures up to 158°F (70°C).
