Topdon Tornado 9000 (T9000) Smart Battery Charger
12V & 24V Intelligent Charging & Stable Power Supply.
Versatility for Cars and Trucks. The Topdon Tornado 9000 is a versatile, all-in-one smart charger designed for both 12V and 24V lead-acid batteries, as well as 12V lithium-ion batteries. Delivering a maximum of 9 Amps (at 12V), it charges batteries up to 300Ah quickly and safely.
Beyond charging, the T9000 features a dedicated 12V Supply Mode. This function acts as a stable power source to maintain vehicle voltage during OBDII diagnostics, preventing battery drain while you work on the vehicle’s electronics.
Why Choose the T9000?
- ✓ Dual Voltage: Charges 12V cars and 24V trucks.
- ✓ Supply Mode: Maintains voltage during diagnostics.
- ✓ 9-Step Charging: Optimizes battery health.
- ✓ Safety First: Spark-proof & reverse polarity protection.
Key Capabilities
9-Step Smart Charging
Utilizes a sophisticated 9-step charging process (Desulphation, Soft Start, Bulk, Absorption, Analysis, Recondition, Float, and Pulse Maintenance) to extend battery life and recover neglected batteries.
12V & 24V Compatibility
A single tool for your entire fleet. Switch effortlessly between charging standard 12V passenger vehicles and 24V commercial trucks, agricultural equipment, or boats.
12V Supply Mode
Provides a constant 13.5V power supply. This is essential for keeping the ECU powered when changing a battery (memory saver) or maintaining voltage while operating diagnostic scanners.
Temperature Compensation
Built-in temperature sensors automatically adjust the charging output based on the ambient climate, preventing over-charging in hot climates and under-charging in cold weather.
Safety Protections
Connect with confidence. The T9000 features comprehensive safety measures including protection against reverse polarity, sparks, short circuits, overheating, and over-voltages.
Rugged Design
The IP65-rated ABS housing protects the internal components from dust and water splashes, while the built-in hook allows you to hang the charger safely out of the way while working.

Topdon Tornado T90000 Battery Support Unit Knowledgebase
Is 90 Amps enough for ECU programming on modern cars?
Yes, for most passenger vehicles. The Tornado 90000 delivers 90A continuous current. This is sufficient to handle the ignition-on load of the vast majority of cars, including many BMW and Mercedes models, preventing voltage drop during critical updates. For extremely high-spec vehicles, the 120A version might be preferred, but 90A covers 95% of the market.
Does this charger work on 24V trucks?
Yes, it is dual voltage. It automatically detects or can be set to charge 24V systems (at up to 45 Amps). This makes it a versatile tool for workshops that handle both cars and light commercial trucks or plant machinery.
Can I use it on Lithium (LiFePO4) batteries?
Yes, it supports Lithium. The T90000 has a dedicated Lithium charging mode compatible with 12V and 24V Lithium Iron Phosphate batteries. This allows you to safely maintain modern performance vehicles that use lightweight lithium starter batteries.
Why should I buy the Tornado 90000 from Mobile Eco Tuning (MET)?
Technical expertise and local stock. We don't just sell boxes; our company, Mobile Eco Tuning, uses Topdon battery support units in the field. We hold genuine UK stock for Next Day Delivery and can provide real technical advice on how to set it up for your specific diagnostic bay.
What is the "Supply Mode" used for?
It acts as a stable power source. In Supply Mode, the unit bypasses the smart charging steps and delivers a constant, clean DC voltage. This is essential for diagnostic work, showroom display, or keeping memory alive while changing a battery.
Can I adjust the voltage output manually?
Yes, fully adjustable. You can dial in the exact voltage required between 11V and 15.8V (for 12V systems). If a manufacturer technical bulletin specifies exactly 13.8V for a coding procedure, you can set the T90000 to match it precisely.
How long are the cables?
Approximately 2.5 metres. The heavy-duty clamp cables give you good reach into the engine bay. If you need longer reach for wall-mounting or boot batteries, check out our T120000 model or ask us about extension options.
Does it have a repair mode for dead batteries?
Yes, a 9-step smart repair cycle. It can detect sulphated or deeply discharged batteries and use a pulsed current to attempt to break down the sulphate crystals, often restoring capacity to batteries that other chargers reject.
Is it safe to leave connected overnight?
Yes, absolutely. The charger uses intelligent monitoring to taper off the current once the battery is full, switching to a maintenance float charge. You can leave it connected indefinitely without risk of overcharging or "boiling" the battery.
Does it monitor temperature?
Yes, dual temperature protection. It has an internal sensor to protect the charger itself and an external temperature probe that monitors the battery. If the battery gets too hot during a high-amp charge, the unit will throttle back to prevent thermal runaway.
Will it restart after a power cut?
Yes, it has memory function. If the mains power fails, the T90000 saves your last settings. When power returns, it automatically resumes the charging or supply mode, ensuring the vehicle is ready for you in the morning.
Is the fan noise distracting?
It is relatively quiet. The fan is temperature-controlled, meaning it only spins fast when the unit is under heavy load (like pushing 90A). For general maintenance or showroom use, it remains unobtrusive.
Can I update the firmware?
Yes, via USB. Topdon releases firmware updates to improve charging algorithms or add features. You can easily update the unit by connecting it to a PC, ensuring your investment stays current with new battery tech.
Does it protect against reverse polarity?
Yes, comprehensive safety. If you accidentally hook the positive clamp to the negative terminal, the unit will detect the error, prevent current flow, and alert you immediately, saving the ECU from damage.
Is it waterproof?
No, it is IP20 rated. It is designed for indoor workshop use. While it is rugged, the active fan cooling means it has air vents, so it should be kept away from wash bays or direct rain.
