Topdon T30A Battery Charger for 6V/12V/24V

The Topdon Tornado30000 (T30A) is a powerful 10A/15A/30A smart battery charger and voltage stabiliser designed for 6V, 12V, and 24V systems. It supports multiple battery types including lead-acid, AGM, GEL, MF, EFB, calcium, and lithium, offering rapid charging, desulfation repair, and maintenance functions — all in one compact unit.

Quick and Efficient Charging

Delivering up to 30A of output, the T30A quickly charges batteries ranging from 50Ah to 1000Ah. It restores and maintains battery capacity through a precise 9-step charging process, ensuring safe, full recharging and long-term maintenance without risk of overcharging.

Wide Compatibility

Ideal for use on cars, motorcycles, trucks, RVs, ATVs, boats, and even industrial batteries such as those used in forklifts, golf carts, and solar systems. It supports 6V/12V/24V lead-acid and lithium-ion batteries, with automatic repair mode to restore battery performance by breaking down lead sulfate buildup.

Smart Safety Features

Built-in protection includes reverse polarity, reverse charging, over-voltage, overheating, and short-circuit safeguards. The ABS flame-retardant housing prevents sparks, while internal cooling fans and temperature sensors adjust operation for all climates.

Reliable Power Supply for ECU Programming

The Tornado30000 doubles as a voltage stabiliser and power supply for ECU programming, reflashing, and diagnostic testing. It can also power 12V and 24V accessories such as inflators, vacuums, and refrigerators while maintaining stable output.

Diagnostic, Recovery, and Maintenance Modes

• Battery Diagnostic – Automatically analyses and diagnoses battery health before charging.

• Desulfation Mode – Restores dead or heavily discharged batteries by breaking down lead sulfate crystals.

• Maintenance Mode – Keeps the battery charged at 100% for long-term connection without damage.

Charging Modes

• 6V Lead-Acid: Normal / Repair

• 12V Lead-Acid & Lithium: Normal / Lithium / Repair / Supply

• 24V Lead-Acid & Lithium: Normal / Cold / Lithium / Repair / Supply

How to Choose the Charging Mode

STEP1 Charge your battery or constant power supply?

If you want to deliver a constant power supply during ECU flashing, reprogramming, and diagnostic testing, choose the SUPPLY/12V or SUPPLY/24V.

If you just want to charge your battery, go to STEP2.

STEP2 Check your battery’s type.

If your battery is lithium-ion, choose 12V 30A/lithium or 24v 15A/lithium. If your battery is lead-acid, go to STEP3.

STEP3 Calculate max current.

First of all, you should check your battery’s voltage and capacity. Then calculate the maximum charging current. (Max current≈capacity ×20%)

STEP4 Choose the suitable charging voltage and charging current.

A suitable charging voltage is slightly higher than your battery's voltage.

A suitable charging current is best not to exceed the max current. A higher current makes a quicker charge.
