Start-stop battery systems, also known as micro-hybrid systems, are a relatively simple yet effective innovation designed to improve the fuel efficiency of internal combustion engine vehicles. The fundamental idea behind these systems is simple: the engine is automatically shut down to save gasoline when the vehicle comes to a halt, such as at a stop sign or in heavy traffic. The engine restarts in a flash when the driver lets off the brake or releases the accelerator. This process is seamless and barely noticeable to the driver.
A start-stop system’s battery is its brains. This battery needs to provide quick and reliable energy to restart the engine multiple times during a typical drive cycle. Consequently, these batteries are specially designed to withstand frequent charge and discharge cycles.
