battery solutions. A modern luxury-class vehicle has some 100 actuator motors that have to be fed with electrical
current.
Then there are the safety, environmental and convenience elements, which are increasingly becoming standard, for
example:
-
Anti-lock brake system (ABS)
-
Dynamic Stability Control (DSC)
-
Electro-mechanical power steering (EPS)
-
Heated catalytic converter
-
Electronic chassis control
-
Air conditioning system
-
Navigation system
Current consumption is considerable even when the vehicle is not in use.
The slightly higher price and greater weight for the same size battery are fully compensated for by the following
benefits:
-
greatly longer service life
-
improved starting reliability at low temperatures
-
reliable starting of engines with high starting current requirements, e.g. high-performance diesel engines
-
100% maintenance-free
-
low risk in the event of an accident (reduced environmental risk)

In contrast to conventional lead-calcium batteries, the sulphuric acid in a battery with fleece technology is not held
freely in the battery housing.
Rather, 100% of the sulphuric acid is bound into the mats of the glass-fibre fleece (separators). For this reason, no
