for stop start systems

Vehicles with Stop Start (SS) systems are often
referred to as mild or micro-hybrids. They have
been developed to improve vehicle fuel efficiency
and reduce CO2 emissions to satisfy global
carbon emission targets.

IDENTIFYING VEHICLES FITTED
WITH STOP START SYSTEMS
Stop Start technology can be incorporated into both petrol
and diesel vehicles with a manual or automatic powertrain.
It may not be possible to identify whether a vehicle
incorporates Stop Start technology, by lifting the bonnet, as
manufacturers will not always promote this technology on
engine components. Some vehicle manufacturers include
a device on the dash board which enables the Stop Start
system to be deactivated as required.
BATTERY CARE & MAINTENANCE
TESTING
Standard battery testing equipment should not be used to
test Stop Start batteries. Century SiS ACTIVE batteries
are designed to operate in a partial state-of-charge. Using a
tester configured for conventional batteries will not provide
an accurate test result.
CHARGING
For optimum performance ensure the battery is maintained
in a fully charged condition.
Always read the manufacturer’s instructions before
attempting to charge a battery and ensure you use a good
quality, Australian approved battery charger. The battery
type and the internal technologies will determine which type
of charger is required.
To avoid fitting an incorrect or conventional battery into a
Stop Start vehicle, refer to the manufacturer’s handbook or
visit www.centurybatteries.com.au
BATTERY REPLACEMENT
When replacing the battery in a Stop Start vehicle, ensure that
the battery used is a like for like replacement. Only replace
EFB with EFB and AGM with AGM Stop Start compatible
batteries. Avoid fitting a conventional battery in a vehicle
with Stop Start technology as this may damage the vehicles
electrical system and lead to premature battery failure.
In Stop Start vehicles the battery is vital to maximising
the environmental benefits of these technologies. Battery
replacement in Stop Start vehicles should be conducted in
conjunction with a compatible Battery Management System
(BMS) or Intelligent Battery Sensor (IBS). This ensures that
all relevant sensors and electrical components are reset and
subjected to a ‘memory test’ which ensures compatibility of
the replacement battery.

RECYCLING
Century SiS ACTIVE batteries are 98% recyclable. Used
batteries should not be discarded with household waste. Visit
www.recyclemybattery.com.au or call 1300 650 702 to find
your nearest CenturyYuasa approved Battery Recycling Centre.
Each battery returned is recycled and
the components reclaimed for use in the
manufacture of other products such as
fertilisers, detergents and plastic bins.

STOP START V’s CONVENTIONAL BATTERIES
Century SiS ACTIVE
Advanced Technology
for Stop Start Vehicles
In constant Stop Start environments
such as those experienced in city
driving, a Stop Start vehicle may stop
and start at least once or twice each
kilometre.
This places extreme demands on a battery
which must be able to cycle constantly and
start the vehicle, even when in a partial
state of charge.
In vehicles fitted with Stop Start systems,
the battery must be able to handle the
rigours associated with constant Stop Start
demands, rapid recharging and the power
requirements needed to run electrical
accessories whilst the engine is switched off.
The battery must also deliver the necessary
cranking capacity to start the vehicle in
a fraction of a second when the brake is
released or the accelerator depressed.

Conventional batteries are not designed
to handle the cycling requirements of Stop
Start systems. In a conventional system
the battery operates in a close to full state
of charge and starts the vehicle two or
three times per day. The capacity used to
start the engine is replaced by the alternator
during the duration of the journey. The
battery is not subjected to constant cycling
or required to operate in a partial state of
charge. Using a conventional battery in a
Stop Start system could potentially damage
the vehicles electrical system and lead to
premature battery failure.

Century SiS ACTIVE batteries are also suitable for use in vehicles which do not incorporate
Stop Start technology as they deliver improved starting power and enhanced cycling capabilities.
Century EFB SiS ACTIVE batteries incorporate porous fibre materials and thicker battery
plates for superior performance and longer life. The specialised low pressure contact
material on the battery plates helps to retain active material and delivers the enhanced
cycling capabilities demanded by Stop Start applications.
Century SiS ACTIVE AGM Range
The advanced AGM technology, suspends liquid electrolyte in highly porous glass fleece
separators. These separators act as a sponge like material, absorbing the liquid electrolyte
and exerting superior contact with the active material in the battery plates. This combines to
deliver superior starting power, extreme cycle life, deep discharge capabilities and up to 3
times higher cycling endurance*.
Century SiS ACTIVE AGM batteries are ideal for use in Stop Start applications as they
deliver a very high current flow in a relatively short time frame and can support electrical
systems with large parasitic drains even when in a partial state of charge.
Extremely durable grids help prevent against plate growth whilst denser active materials
incorporating fine carbon blends deliver up to 15% more cranking performance and up to
2 x higher cycling endurance than conventional batteries.
The SiS ACTIVE EFB range includes DIN style maintenance free batteries for popular European
vehicles plus low maintenance flooded batteries for Asian vehicles.
