Heavy-duty commercial vehicles demand starting power that remains consistent across extreme load cycles and adverse operating conditions. The Bosch T4078 is a 12V 170Ah HD Truck Battery engineered to meet those demands, supplying reliable cranking performance and sustained power delivery for trucks and large commercial vehicles operating under normal to heavy energy requirements.
Built using Bosch PowerFrame? grid technology, the T4078 benefits from a cast-on-strap construction that reduces internal resistance, improves charge acceptance, and extends cycle life compared with conventional lead-acid designs. PowerFrame? grids are produced to tight dimensional tolerances, ensuring consistent plate geometry and electrolyte distribution throughout the service life of the battery.

The battery features Terminal Placement 3 (positive terminal left, negative terminal right when viewed from the front), Type 1 terminal posts, and Hold-Down type B03. It cross-references to the industry-standard 620HD group designation. Start-stop compatibility is not confirmed – refer to the product label before fitment.
The T4078 is one of ten variants within the Bosch T4 and T3 HD commercial range available from PartsForMachines, covering differing capacities and footprints to suit a broad spectrum of truck and fleet applications."
