is replaced, the battery<br />
management system should<br />
be re-set.<br />
Good news for the aftermarket<br />
comes from cars<br />
without stop/start systems,<br />
because in this case there is<br />
always the possibility of selling<br />
an upgrade. Yuasa says<br />
it’s important for workshop<br />
staff to ask the customer<br />
what sort of driving they do,<br />
and roughly how many miles<br />
they cover every year – for<br />
those doing shorter (under<br />
20 minutes) journeys a higher-specification<br />
replacement<br />
is advised, Yuasa says.<br />
But while traffic is getting<br />
heavier and journeys<br />
shorter, just how much call<br />
is there for cars with stop/<br />
start systems? According<br />
to Hella 90 percent of cars<br />
built now have the feature.<br />
And for those cars that have<br />
the system over-ride feature,<br />
the number of drivers activating<br />
it has reduced as they<br />
becoming more accepting of<br />
the green-principled technology.<br />
To extend the battery life<br />
of cars with a stop/start system<br />
requires a form of monitoring,<br />
and Hella’s Intelligent<br />
Battery Sensor gives precise<br />
measurements of current,<br />
voltage and battery temperacontinued<br />
