Pulse Tronic Technology: The Smart Heart of Your Battery
Pulse Tronic technology is an advanced electronic control system for battery charging and maintenance, patented by Telwin. It is based on continuous, intelligent diagnostics of the battery condition, analysing its internal parameters in real time. On this basis the system dynamically selects the optimal charging conditions from 8 available stages, which include analysis, (pulse) desulfation, bulk charging, absorption, a check of charge retention and pulse maintenance.
Thanks to this precise control, the T-CHARGE 20 EVO not only charges the battery efficiently to its full capacity but also actively looks after its condition. It minimises the risk of overcharging, gassing or overheating, which is crucial for safety and service life, especially with GEL, AGM or LiFePO4 batteries. In addition, special maintenance algorithms allow the charger to stay connected safely for an unlimited time, keeping the battery ready for use without the risk of degradation. For a professional this means the certainty that every battery, regardless of its type or initial condition, is treated individually and with the greatest care, maximising its service life and reliability.
Full Control: Diagnostic, Recovery and Supply Functions
The TELWIN T-CHARGE 20 EVO is much more than a standard charger. The unit has a number of advanced functions that make it a versatile diagnostic and maintenance tool. The TEST function lets you check the key parameters quickly and precisely: the open-circuit voltage of the battery, its cranking capacity (CCA, Cold Cranking Amps) and the correct operation of the vehicle charging system (alternator test). The results are shown on a clear LCD display, so you can assess the state of the power system at a glance.
Another strength is the RECOVERY function, designed for regenerating sulfated batteries. It applies special current pulses that help dissolve the lead sulfate crystals deposited on the battery plates, often restoring lost capacity and cranking power. For many batteries that would otherwise have to be replaced, this is a real chance of a "second life".
The SUPPLY function is also extremely practical. It lets you use the T-CHARGE 20 EVO as a stabilised 12V power source. This is invaluable when replacing the battery in modern vehicles, where holding the voltage in the electrical system prevents the loss of settings in the on-board computer, radio or comfort systems. The function is also essential during diagnostic work with scan tools, ECU software updates or vehicle presentations in showrooms, where a constant and dependable power supply is required.
Versatility and Safety: Charging Different Battery Types, Including Lithium, on a 110V Supply
The TELWIN T-CHARGE 20 EVO in the 110V version was designed for global compatibility and maximum safety. The 110V supply opens the way to advanced Italian technology in markets and environments where this standard dominates. Regardless of the input voltage, the unit offers the full set of functions and the same high level of operating refinement.
A key advantage is its ability to handle practically all common 12V and 24V battery types: from conventional lead-acid batteries (WET, maintenance-free MF, Ca/Ca), through absorbent glass mat (AGM) and gel (GEL) batteries, to modern EFB (Enhanced Flooded Battery) batteries used in vehicles with Start-Stop systems. Importantly, the T-CHARGE 20 EVO also has a dedicated program for charging 12V LiFePO4 lithium batteries, which require very precise charging algorithms to ensure their safety and maximum service life.
The safety of the user and the connected equipment is a priority. The charger has full protection against reverse polarity (with indication), short-circuited clamps, current overload and overcharging of the battery. This means that even less experienced users can work with the unit without worry. The IP65 protection rating guarantees dust tightness and resistance to water jets, allowing safe use even in harsh workshop conditions.

Key Features and Benefits
- Advanced Pulse Tronic Technology: The heart of the unit, managing the fully automated 8-stage charging and maintenance process. The system intelligently analyses the battery condition and adjusts the charging parameters in real time, including pulse regenerative charging. For a professional this means reliably optimal charging of every battery type, minimal risk of damage, battery life extended by up to 40% and the possibility of recovering deeply discharged or sulfated cells, which translates into real savings.
- 12V/24V Voltages and Battery Type Versatility: The T-CHARGE 20 EVO automatically detects the voltage of the connected battery (12V or 24V) and is compatible with a broad spectrum of technologies, from conventional lead-acid (WET, MF, PbCa), through gel (GEL) and AGM, to modern EFB (Enhanced Flooded Battery) and lithium (12V LiFePO4). This versatility removes the need for several chargers and simplifies work in workshops that service different vehicles, from motorcycles and cars to trucks and agricultural machinery.
- Smart Diagnostics and Recovery Functions: The unit offers more than charging. The TEST function lets you quickly check the battery voltage, its cranking capacity (CCA) and the condition of the vehicle alternator. The RECOVERY function starts a desulfation process that can bring older or neglected batteries back into service. For the user this means time saved on diagnostics and possibly avoiding an expensive battery replacement.
- Electronics Safety and User Protection: The T-CHARGE 20 EVO has a full set of protections against reverse polarity, short circuit, overload, sparks and overcharging. Charging can take place without disconnecting the battery from the vehicle electrical system, which protects advanced electronic systems from damage. The professional gains peace of mind and the certainty that both the battery and the vehicle are fully safe throughout the process.
- SUPPLY Function for a Stable Power Supply: A very useful function for workshops that keeps the vehicle electrical system powered during battery replacement (protecting the on-board computer settings and data) or during diagnostic work and ECU programming that requires a stable voltage. This means uninterrupted work and no problems caused by a power loss.
- COLD Mode for Extreme Conditions: A special charging program optimised for low temperatures. In such conditions batteries need a different charging algorithm to reach full capacity and avoid damage. The T-CHARGE 20 EVO adjusts the parameters automatically, ensuring effective and safe charging even on frosty days, which is essential for users in colder climates or for vehicles parked outdoors.
- 110V Supply for Global Compatibility: This version of the product is specially adapted to run on 110V mains voltage, which makes it an ideal solution for markets and applications where this standard is common (e.g. North America, specialised industrial installations).
