TOPDON T4000 6v - 12v Intelligent Battery Charger & Maintainer

TOPDON Tornado4000 6V/12V Smart Battery Charger

The TOPDON Tornado4000 is a battery maintainer, trickle charger, desulfator and DC power supply in one compact unit. It charges 6V and 12V lead-acid batteries and 12V lithium batteries from 5Ah to 120Ah, and its supply mode holds a steady 13.5 V DC at up to 4 A.

Charging Modes

• 12V NORM: standard 12V lead-acid charging
• 12V LI: 12V lithium charging
• 12V REP: repair mode for ageing batteries
• 12V SUP: power supply mode for 12V devices such as tyre inflators, lamps and fans
• 6V NORM: 6V lead-acid charging
• Charging starts automatically once a mode is selected, and the last mode resumes when power is restored

Key Features

• Patented 9-step smart charging for lead-acid batteries covers charging, maintenance and repair, and a 5-step smart mode is used for lithium
• Stable power supply: 13.5 V at up to 4 A (54 W), which also acts as a voltage stabiliser during ECU programming
• Pulse desulfation breaks down sulphates in ageing batteries and restores internal resistance
• Adaptive power: charging power reduces automatically with charger and ambient temperature
• 4 error indicators: reverse connection or short circuit, bad battery, charging timeout and over-temperature
• Protections: over-temperature, short circuit, over-voltage, reverse connection and spark prevention
• IP65 dust and water resistance in a flame-retardant ABS housing
