Some premium vehicles have premium safety demands. Due to the complex electronic equipment in these vehicles, the cars must have spare energy supplies in case there’s a problem with the main battery. Energy consumption is also much greater in these types of vehicles, so you can always use Back-Up Power batteries as absolutely necessary prevention of problems. Smaller batteries are used in Start-Stop function vehicles and vehicles with higher energy consumption (vehicles with various safety systems and electronic steering). The same pioneering AGM technology as used in Start-Stop batteries makes Back-Up Power batteries perfect to support the main battery.
