The brand
One hundred years of manufacturing batteries in Germany
With more than one hundred years of manufacturing in Germany, VARTA is a reference manufacturer in Europe and a first-tier supplier for numerous vehicle manufacturers. That position explains why its catalog covers the exact specifications required by each application.
All references carry the European ETN code, which uniquely identifies capacity, starting performance, and format. It is the data that allows verification of equivalence without relying on the commercial name.
The range
VARTA ProMotive SLI
They are built to withstand the continuous vibration of heavy transport: plates anchored with resin, reinforced grid and casing prepared for severe work. The capacity and starting current are much higher than those of a passenger car, because a large displacement diesel engine requires a much higher starting torque, especially in cold weather.
ProMotive SLI is the starting range for industrial vehicles: truck, bus, tractor and machinery. It groups what was previously sold as ProMotive HD and ProMotive SHD.
