Idle Stop Start (ISS) Batteries

Many modern cars are now fitted with Idle-Stop-Start (ISS), a technology which saves fuel & CO2 by stopping the engine when the vehicle is stopped in traffic. This technology needs a special car battery as the frequent restarts quickly damage a normal car battery and can invalidate the vehicle and battery warranty.

What are ISS systems?

Vehicles fitted with Idle Stop Start systems are often referred to as mild or micro hybrids. They have been developed by vehicle manufacturers to improve vehicle fuel efficiency and reduce CO2 emissions to satisfy global carbon emission targets.

How do ISS systems work?

Basic Idle Stop Start systems work by shutting off the engine whilst the vehicle is stationary. When the brake pedal is released or the accelerator depressed, the engine quickly re-starts enabling the vehicle to be driven.

In more advanced Idle Stop Start systems, the vehicle may also incorporate regenerative braking or engine power assistance technology. This technology has the ability to switch off the engine when the vehicle is coasting or braking as well as whilst stationary. Shutting off the engine eliminates the amount of fuel that would otherwise have been used, reducing both vehicle emissions and fuel consumption.
