Today s conventional car battery has come a long way, but the tasks of starting the engine and supplying stored energy for lighting, driving and comfort controls have remained largely unchanged. However, the new generation of Start-Stop cars puts far greater demand on the battery to work harder and requires many more thousands of starts during the battery s lifetime.

The global shift led by European car manufacturers towards Start-Stop cars required a totally new kind of battery. Exide s expertise and vast experience in stored energy for automotive

and industrial applications put the company in prime position to develop Start-Stop batteries designed to cut fuel consumption and reduce CO2 emissions.

On the outside, Start-Stop batteries appear very similar to conventional car batteries, but the technology inside the box is vastly different. Even entry-level Start-Stop vehicles demand twice the endurance of the very best premium battery. Larger cars with Start-Stop and those featuring Regenerative Braking require higher charge acceptance and three times the endurance level.

It is extremely important to respect the car manufacturers specification and always use an Original Spare Part. Exide s Battery Finder (App or online) will ensure the correct match of battery. Incorrect fitment will reduce battery life and the effectiveness of the Start-Stop system.

Be cautious of cheaper, less well-known brands, assuming that all AGM or EFB batteries are the same. Only a small number of battery manufacturers meet today s complex Original Equipment specifications. Other AM suppliers may offer a product based on out-of-date designs, produced with cheaper lower grade materials and produced using less precise processes. In such cases, stratification effects can quickly occur, which will have a significant impact on the overall energy and in-cycle voltage stability within the Start-Stop operations.

A NEW GENERATION OF BATTERIES

Typical pattern of State of Charge during a journey with Start- Stop system

Designed and built to endure continuous battery discharge and recharge of Start-Stop systems.

Exide EFB offers significant performance advantages over a conventional battery also when fitted into a car without Start- Stop system.

EXIDE AGM Absorbent Glass Mat

Ideal for large cars, SUVs, vans and vehicles with Start- Stop and power-hungry electrical equipment

EXIDE EFB Enhanced Flooded Battery

Ideal for small to mid-sized cars with Start-Stop or extra life for conventional vehicles

Exide launched the first Start-Stop batteries... AGM IN 2004 & EFB IN 2008

The 2004 Citroën C2 was the first successful production car featuring Start-Stop. To function well, the system depended upon Exide s new AGM battery.
