In order to show us that it is a car manufacturer that always thinks of its customers, Porsche revealed its new starter battery in lithium-ion technology. For those who don´t know, Porsche is currently the first car maker in the world to offer this battery and says that this weighs less than 6 kg or 13 lb, which means that it is with 10 kg or 22 lb lighter than a conventional 60 Ah lead battery.
Starting January 2010, the new battery will be available for the 911 GT3, 911 GT 3 RS, and Boxster Spyder at a price of €1,904 including 19 per cent value-added tax. Porsche is planning to deliver this battery as a separate unit together with the car and may subsequently be fitted as an alternative to the regular, conventional starter battery.
From the press release: "The primary reason for developing and introducing the new battery was its lower weight. In sports cars built consistently for superior driving dynamics such as the two versions of the 911 GT3 and the Boxster Spyder, less weight naturally means even greater agility and driving dynamics. In its length and width the lithium-ion battery comes in the same dimensions as the regular battery, but is approximately 70 millimetres or 2.8 lower. The fastening points, electrical connections and voltage range are fully compatible with the respective models, allowing simple and quick replacement of the standard lead battery by the lightweight unit, for example when racing on the track. With its nominal capacity of 18 Ah, the lithium-ion battery, through its specific features, offers a level of practical output and performance not only comparable to that of a 60 Ah lead battery, but rather even better in many cases. On a conventional car battery only about 30 per cent of the total capacity is actually available for practical use due to the configuration of the system, while this restriction does not apply to the lithium-ion battery. On the contrary, through its characteristic structure and, in particular, the independence of the chemical composition of the electrolytes from the charge status a lithium-ion battery consistently offers almost 100 per cent of its capacity."
