The newly developed lead-acid battery is optimal for start-stop use and meets original equipment quality standards. It offers reliable starting even in extreme cold and high operational reliability, performing well under increased energy requirements. The special double lid design provides the necessary leakage protection to meet the high demands of the automotive industry, ensuring enhanced safety, comfort, and performance. It offers the highest leakage protection in accordance with German automotive industry requirements, making it ideal for installations in the vehicle interior. The battery features improved safety against leakage current and self-discharge, along with double backfire protection and specially designed screw connections with moulded-on components. It includes multiple seals for ESD safety and electrostatic breakdown testing. High operational safety is ensured through reliable pressure build-up, acid return, and acid retention, even during intensive charging and in tilted positions.
