TELWIN DOCTOR CHARGE 55 CONNECT redefines charging through the synergy of two key technologies. Power Stream is Telwin’s proprietary solution that optimizes the charging curve, delivering current in a way that maximizes energy absorption by the battery. This results in a reduction in charging time of up to 50% compared to conventional chargers, without the risk of overheating or damaging cells.

This is complemented by Pulse Tronic, an intelligent 8-stage charging and maintenance process. This system automatically analyzes the state of the battery (voltage, degree of sulfation, temperature with an optional sensor) and dynamically selects the optimal parameters for each of the 8 phases: TEST (condition check), DESULPHATION (pulse desulfurization), ANALYSE (charge holding capacity analysis), MAIN CHARGE (maximum current charging), FINE CHARGE (charge with decreasing current to full), VERIFY (charge verification), FLOAT (constant voltage maintenance), PULSE (pulse regeneration and long-term maintenance). As a result, WET, GEL, AGM, MF, PbCa, EFB and even LiFePO4 batteries are charged with precision, resulting in maximum performance and a significant extension of their service life.

DOCTOR CHARGE 55 CONNECT is a real diagnostic center for batteries. The device offers a range of tests to comprehensively assess the condition of not only the battery itself, but the entire charging system in the vehicle. The battery voltage test allows you to quickly assess its basic state of charge. The Cold Cranking Amps (CCA) test verifies that the battery is capable of delivering the adequate current needed to start the engine, which is crucial especially in cold weather. The alternator efficiency test verifies that the vehicle’s charging system is working properly and charging the battery efficiently while the engine is running.

An extremely valuable feature is RECOVERY, which is a desulfurization and regeneration program. Sulfation is a major cause of premature degradation of lead-acid batteries. DOCTOR CHARGE 55 CONNECT uses special current pulses to dissolve lead sulfate crystals deposited on the plates, restoring partially or completely lost capacity. For a professional service provider, this means being able to offer customers a reconditioning service instead of an immediate, expensive battery replacement, building their trust and loyalty.

Today’s vehicles are saturated with advanced electronics that are extremely sensitive to voltage fluctuations. The SUPPLY function of the TELWIN DOCTOR CHARGE 55 CONNECT transforms the device into a stabilized power supply. This is invaluable when performing computer diagnostics, where a stable voltage is crucial for proper communication with controllers. Similarly, when programming or updating driver software (ECU flash), where any instability in the power supply can lead to irreparable damage to the module.

The SUPPLY function is also essential when replacing the battery. Connecting DOCTOR CHARGE 55 CONNECT before disconnecting the old battery allows the device to maintain power in the vehicle(Memory Saver function), preventing the loss of settings for the radio, clock, on-board computer, adaptive engine maps or comfort system configurations. The professional repairer will also appreciate the ability to use the device as a stable power source during vehicle presentations at the dealership, allowing demonstration of electronic functions without worrying about battery drain.

TELWIN DOCTOR CHARGE 55 CONNECT takes battery management to a new level with its integrated CONNECT function. Using Bluetooth technology (or Wi-Fi, depending on the specific model implementation), the device can communicate wirelessly with a dedicated mobile app installed on a smartphone or tablet (iOS/Android).

With the app, the user gains the ability to remotely monitor the entire charging process in real time. You can track the current voltage, current, charging phase and estimated time to completion, even without being directly at the device. The app also allows remote control – selecting a charging program, running tests or regeneration functions. What’s more, it often offers access to charging history and diagnostic reports, which is extremely useful for managing a fleet of vehicles or documenting maintenance services performed. This functionality significantly increases convenience, work efficiency and gives you full control over the condition of your batteries, wherever you are.
