TOPDON T4000C 6V/12V 4A battery Charger-Maintainer

The TOPDON T4000C is a charger-maintainer suitable for all types of vehicles (cars, motorcycles, recreational boats etc.) and all 12V/6V battery types: WET, MF, SMF, AGM, EFB, CAL, GEL and LI.

It features 5 charging modes and is ideal for batteries from 5Ah to 120Ah with a charging current of 4A:

1. 12V Normal
2. 12V Lithium
3. 12V Repair
4. 12V Supply
5. 6V Normal

The T4000C can also be used as a power supply for 12V devices such as tyre inflators, lamps, fans etc., using the "SUPPLY" 12V mode. Additionally, its battery desulfation function effectively restores battery resistance, extends battery life and revitalizes the battery by bringing it back to a healthy state. The charger offers one-touch charging and includes a memory function that resumes charging according to the last selected mode when powered back on after being turned off.

Four Error Indicators

The T4000C is equipped with four error indicators that light up when the corresponding condition occurs:

1. Reverse connection/short circuit
2. Defective battery – the battery voltage rises abnormally
3. Charging time exceeded – more than 10 hours in a single stage
4. Overheating – above 120°C (248°F)

IP65 Protection

The T4000C features a durable ABS housing, making it ideal for humid environments and capable of withstanding temperatures up to 70°C. It is resistant to dust and offers protection against reverse polarity, sparks, short circuits, overvoltage, and overheating.
