| The power required by electrical components
and systems in a car has steadily increased over the last decade. In response,
Bosch has developed a 'HighTech' battery with AGM technology for a reliable
power supply for modern cars at start-up and during all driving conditions.
AGM, or Absorbent Glass Mat, is a non-woven fabric made from micro-fine
fibreglass which safely absorbs sulphuric acid in lead accumulators and
prevents leakage. AGM batteries have already demonstrated, in original
equipment conditions that they are deep-cycle resistant.
They may be recharged up to 300 times, which is three more than conventional
starter batteries. The new battery line is, moreover, totally maintenance
free, spill and leakage proof and shock resistant.
The Bosch AGM HighTec is available in two models, which will provide an
overall market coverage of 90 per cent - based on cars that are already
fitted with AGM batteries as original equipment. The battery type with
70 amp hr capacity delivers a starter current of 760 amps, the 95 amp
hr battery delivers 850 amps at engine start.
The reason for the increased demand for electrical power in a car is explained
by the growing number of electrical and electronic safety and convenience
systems now being fitted. They help to make passenger cars safer, more
economic and more comfortable - however, they increase the consumption
in electrical energy.
In a modern mid-range car, the power consumption reaches more than 3,500
watts. In the Nineties, the value for a lower to mid-range passenger car
amounted to only 950 watts.
AGM HighTec batteries are not only recommended for cars with high power
consumption, but in some cases can be recommended for older passenger
cars if, for example, auxiliary heating is retrofitted. The AGM HighTec
battery will not only guarantee permanent and continuous energy supply
of these functions but provide great reliability for starting.
