The dual-battery system was adapted to the new requirements and introduced on other cars by the same manufacturer. The demand for batteries significantly increased in 2008 following the introduction of Start&Stop systems. Batteries with new and different specifications designed for Start&Stop application.

Production is started in Wuhan (China) and almost eight million units have been made since 2010. The same batteries have also been made at the plant in Avezzano (Italy) since 2019.
