With its numerous functions, the DOCTOR START range developed by Telwin meets all the requirements placed on a professional workshop charger. From jump starting, automatic charging, battery maintenance and regeneration to alternator voltage testing, DOCTOR START is a versatile and extremely efficient solution for professionals. Thanks to the illuminated LCD display, access to all functions is intuitive and fast, which facilitates operation even in poor lighting conditions.


The maximum starting power of 300-570 A makes this series the ideal choice for starting many different types of 12V and 24V vehicles such as cars, vans, trucks, tractors and construction equipment. These multifunction electronic chargers with Pulse Tronic technology have a Charge function and an effective charging current of 45 A to 90 A. This guarantees optimum automatic charging and maintenance for 12V and 24V wet cell, gel, AGM, PbCa, EFB and lithium batteries. The Recovery function can also be used to desulphate batteries that are already sulphated, thereby restoring performance.


The DOCTOR START’s test functions also allow the alternator voltage, starting capacity and vehicle battery charge to be checked. It is particularly important to check the alternator voltage as vehicle battery charging cannot be guaranteed if this is too low. The Supply function also ensures a stable power supply to protect the on-board electronics during battery changes and software programming.
