About Idle Stop Start Batteries

Vehicles fitted with Idle Stop Start (ISS) systems are often referred to as mild or micro hybrids and have been developed by vehicle manufacturers to improve vehicle fuel efficiency and reduce emissions in line with environmental regulations.

An ISS System works in some situations by shutting off the engine when the vehicle stops, is idling or when the brake is applied. Once the accelerator is depressed the engine restarts enabling the vehicle to be driven. By shutting off the vehicle’s engine, the ISS system eliminates the amount of fuel that would otherwise have been used, thus reducing emissions and fuel consumption.
Century ‘SiS ACTIVE’ batteries are specially designed for use in ISS systems and feature industry leading design features to ensure superior performance and maximum fuel saving.
