Introduction
In September 2002, the first so-called VRLA batteries, better known as AGM batteries came into use. (VRLA stands for Valve Regulated Lead Acid, i.e. lead-acid battery with pressure relief valve; AGM stands for Absorbent Glass Mat, i.e. absorbent glass-fibre fleece).
The constantly increasing energy demand of modern vehicle electrical systems calls for ever more powerful battery solutions. A modern luxury-class vehicle has some 100 actuator motors that have to be fed with electrical current. Added to these are safety, environmental and comfort elements which are increasingly becoming standard features, such as e.g. Antilock Brake System (ABS), Dynamic Stability Control (DSC), steering assistance (EPS), electronic chassis and suspension control, air conditioning and navigation system. Current consumption is considerable even when the vehicle is not in use.
The somewhat higher price compared with a battery of similar size is fully balanced 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 % freedom from maintenance
- low risk in the event of an accident (reduced environmental risk)
