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 />
