Varta batteries are the optimal choice for vehicles with start-stop technology. Varta offers two types of batteries: Start-Stop batteries which are well-suited for basic start-stop functions, and Start-Stop Plus batteries which can handle advanced start-stop systems with regenerative braking and additional fuel-saving technologies. Start-Stop Plus batteries have absorbent glass mat technology, thicker plates, and higher cycling ability than standard or Start-Stop batteries. They provide reliable power for more engine starts and longer periods with the engine off. By 2015, 70% of new vehicles are expected to feature start-stop technology, highlighting the growing importance of innovative battery solutions.
