What is an advantage of a battery-based ignition system?

A battery-based ignition system is advantageous because it can provide stable ignition at all motor RPM (revolutions per minute). This stability is crucial for optimal engine performance, as a consistent spark is necessary for efficient combustion at varying speeds. Unlike some ignition systems that may struggle to produce a reliable spark at low or high RPMs, a battery-based system ensures that the ignition remains effective throughout the entire range of engine operation. This consistency translates into smoother performance, better fuel efficiency, and reduced emissions, making it an essential feature in many modern engine designs.

In contrast, while other options mention higher voltage, cost of manufacturing, and maintenance requirements, they do not encapsulate the core function of an ignition system as effectively as the ability to deliver stable performance across different operating conditions.
