Start-Stop batteries achieve four times longer cycle life

September 11, 2014 // By Paul Buckley
Exide Technologies' AGM Start-Stop battery claims to achieve four times longer cycle life which is 20% more power and more than three times the charge acceptance of a standard conventional battery.

Similar gains will also be seen in Exide's new EFB battery.

Start-Stop vehicles already constitute 15% of the car park, and this will reach 50% within the next five years. Only specially designed batteries can be used in Start-Stop vehicles, which is causing a huge shift in the battery market.

Exide invented the first Start-Stop AGM battery back in 2004 and the first EFB battery in 2008. The company's technology has improved at a rapid pace, and the new range will support sailing, energy recuperation and all the latest fuel-saving features.

Cars with conventional powertrains can be fitted with AGM and EFB batteries to improve performance and reduce long-term costs. The technology is useful for special vehicles like ambulances and police cars, cars with power-hungry electrical equipment and scenarios where the battery is exposed to extreme driving conditions.

The Exide light vehicle battery range will be unveiled at the Automechanika trade fair in Frankfurt in September 2014 at F10 in Hall 3.1, where the AGM and EFB batteries will be revealed for the first time.

Also to be launched at utomechanika will be Exide Technologies' Premium battery which has been developed to recharge up to 1.5 times faster with the performance gains coming from new Carbon Boost technology developed by Exide.

Carbon Boost was first developed for Exide's Start-Stop AGM and EFB batteries, based on years of intense research and experimentation. The carbon additives lead to improved charge acceptance and a reduction in charging times. Exide has continued to make investments in the technology, and will now apply them to conventional batteries for the first time.

Standard batteries suffer from a build-up of sulphate particles on their negative plates during discharge. This non-conductive layer inhibits recharging, since much of the energy goes into dissolving the sulphate on the plates. Exide discovered that including certain carbon additives improves the surface area and the conductivity. This effect causes the sulphate particles to
