Pulse Tronic technology is Telwin’s patented, advanced electronic control system for battery charging and maintenance. It works on the basis of continuous, intelligent diagnostics of the battery’s condition, analyzing its internal parameters in real time. Based on this, the system dynamically selects the optimal charging conditions from among 8 available stages, which include analysis, desulfurization (pulsed), base charging, absorption, charge retention verification and pulsed maintenance.

Thanks to this precise management, the T-CHARGE 20 EVO not only efficiently charges the battery to its full capacity, but also actively cares for its condition. It minimizes the risk of overcharging, gassing or overheating, which is crucial for safety and longevity, especially for GEL, AGM or LiFePO4 batteries. What’s more, special maintenance algorithms allow the charger to be safely plugged in for an unlimited period of time, keeping the battery ready without risk of degradation. For the professional, this means the assurance that each battery, regardless of its type or initial condition, will be treated individually and with the utmost care, maximizing its life and reliability.

The TELWIN T-CHARGE 20 EVO is much more than a standard charger. The device is equipped with a number of advanced features that make it a versatile diagnostic and maintenance tool. The TEST function allows you to quickly and precisely check key parameters: the battery’s resting voltage, its starting capacity (CCA – Cold Cranking Amps) and the correctness of the vehicle’s charging system (alternator test). The results are presented on an easy-to-read LCD display, allowing instant assessment of the power system’s condition.

Another advantage is the RECOVERY function, dedicated to regenerating sulfated batteries. This process involves the application of special current pulses that help dissolve lead sulfate crystals deposited on the battery plates, often restoring lost capacity and starting ability. This is a real chance for a “second life” for many batteries that would otherwise have to be replaced.

The SUPPLY function is also extremely practical. It allows the T-CHARGE 20 EVO to be used as a stabilized 12V power source. This is invaluable when replacing the battery in modern vehicles, where backing up the voltage in the system prevents the loss of settings of the on-board computer, radio or comfort systems. This function is also indispensable during diagnostic work with scanners, driver (ECU) software updates or vehicle presentations in showrooms, where a constant and reliable power supply is required.

The TELWIN T-CHARGE 20 EVO 110V version is designed for global compatibility and maximum safety. The ability to be powered by 110V opens the way for the use of advanced Italian technology in markets and environments where this standard is prevalent. Regardless of the input voltage, the device offers a full range of features and the same high operating culture.

A key advantage is its ability to handle virtually all popular types of 12V and 24V batteries: from traditional lead-acid (WET, maintenance-free MF, Ca/Ca), through glass mat (AGM) and gel (GEL) batteries, to modern EFB (Enhanced Flooded Battery) batteries used in Start-Stop vehicles. Importantly, the T-CHARGE 20 EVO also has a dedicated program for charging 12V LiFePO4 lithium batteries, which require very precise charging algorithms for their safety and maximum life.

The safety of the user and the connected equipment is a priority. The charger has comprehensive protection against pole swapping (with signaling), terminal short-circuiting, current overload and battery overcharging. As a result, even less experienced users can use the device without worry. The IP65 degree of protection guarantees dustproofing and resistance to water jets, allowing safe use even in harsh workshop conditions.
