Difference between Battery Ignition System and Magneto Ignition System

Sharing is Caring :)-

Today we will difference between Battery Ignition System and Magneto Ignition System. These both are major ignition system used in both light and heavy engines. In battery ignition system a battery and ignition coil is used to generate spark at spark plug but in magneto ignition system necessary energy is generated by its own electric generator. It is mounted on the engine and replaces all component of battery ignition system except spark plug. We have discussed both of these in previous articles. Today we will differentiate them.
Difference between Battery Ignition System and Magneto Ignition System

Difference between Battery Ignition System and Magneto Ignition System:


Battery Ignition System

Magneto Ignition System

As the name implies, battery is necessary in this type of ignition
No battery is needed in this type of ignition system. It has its own electric generator.
It is difficult to start when the battery is discharge.
There is no such problem because no battery is used.
It required high maintenance due to battery.
It required less maintenance.
In battery ignition system current for primary circuit is obtain by battery.
In magneto ignition system, required electric current is generated by the magneto, which is an electric generator.
Spark strength does not depend on speed of engine due to current is
supplied by battery.
Spark strength depends on speed of engine due to magneto.
Good spark is available at low speed.
During starting or at low speed, quality of spark is poor.
Efficiency of system decreases with the reduction in spark intensity as engine speed rises.
Efficiency of the system improves as the engine speed rises due to high intensity spark.
Battery ignition system occupies more space.
Compare to battery ignition system, magneto ignition system requires less space.
Commonly employed in cars and light commercial vehicles.
It is mainly used in racing cars and two wheelers.


These are all major differences between battery ignition system and magneto ignition system. If you have any query regarding this article, ask by commenting. If you like this article, don’t forget to share it on social networks. Thanks for reading it.
