Pulse Tronic is the heart and brain of DOCTOR CHARGE 50, transforming the charging process into an intelligent operation. The system constantly analyzes the state of the battery, using a series of short pulses to diagnose and optimize each phase. The eight charging phases are: STEP 1 (CHECK) – checking the condition of the battery; STEP 2 (DESULFATION) – removing sulfates from lead plates for sulfated batteries; STEP 3 (ANALYSE) – analyzing whether the battery can accept a charge; STEP 4 (MAIN CHARGE) – charging with maximum current until 80% capacity is reached; STEP 5 (FINE CHARGE) – charging with decreasing current until 100% capacity; STEP 6 (VERIFY) – verifying that the battery holds a charge; STEP 7 (FLOAT) – maintaining a fully charged state with constant voltage; STEP 8 (PULSE) – pulse charging to maintain an optimal state of charge.

Thanks to this advanced logic, the DOCTOR CHARGE 50 not only charges efficiently, but also actively cares for the condition of the battery, preventing premature wear caused by sulfation, overcharging or undercharging. Professionals will appreciate the precision that translates into longer battery service life and fewer complaints, while hobbyists will appreciate the assurance that their precious batteries are being treated with the utmost care.

TELWIN DOCTOR CHARGE 50 is much more than just a charger – it is a comprehensive diagnostic tool. The TEST function allows you to quickly and accurately check key parameters of your vehicle’s power system. You can instantly measure the battery’s current voltage, which gives an initial assessment of its state of charge. Then, the device can perform a test of starting capacity (often expressed in CCA – Cold Cranking Amps), simulating the load on the starter and assessing whether the battery can deliver adequate current.

Another key element is the alternator test, which verifies that the vehicle’s charging system is working properly and delivering the right voltage to the battery while the engine is running. Detecting problems at this stage can prevent more serious failures and multiple discharges of even a new battery. For a professional garage, having these functions in one device means saving time, increasing the accuracy of diagnoses and being able to offer customers a comprehensive electrical system inspection service.

DOCTOR CHARGE 50 offers three key functions that make it an invaluable support in daily workshop work. The RECOVERY (Desulfation) function is a specialized regeneration program for batteries that have lost some of their capacity due to sulfation. The device generates controlled current pulses that help dissolve lead sulfate crystals deposited on the plates, potentially restoring the battery to full capacity and saving replacement costs.

The BOOST (Starting Assist) function is invaluable when the battery is too weak to start the engine. DOCTOR CHARGE 50 then provides safe, extra current, making starting easier. This is especially useful in cold weather or when operating vehicles with larger engines. SUPPLY mode, on the other hand, is an absolute must when working on modern vehicles. It allows the vehicle’s electrical system to sustain power during battery replacement (preventing resetting of settings and systems) or during prolonged computer diagnostics and programming of control units (ECUs), where stable voltage is crucial to the safety and success of operations.
