Comparison Between Battery and Magneto Ignition System

Comparison between battery ignition system and magneto ignition system can be made in aspects like an engine starting when the battery is discharged, efficiency, battery maintenance, space requirement, recharging, etc.


S.no
1 In a battery ignition system, a battery is necessary for the engine to start. The magneto ignition system requires no battery for the engine to start.
2 Difficulty starting the engine when a battery is discharged. There is no problem with battery discharge.
3 Battery Maintenance is required. No battery maintenance problems.
4 The current for a primary circuit is obtained from the battery. The required electric current is produced from the magneto.
5 A good spark is available at the spark plug, even at low speed. During the starting of the engine, the quality of the spark is poor due to low speed.
6 The efficiency of the battery ignition system decreases with the reduction in spark intensity as engine speed rises. The system's efficiency improves as the engine speed rises due to high-intensity sparks.
7 Occupies more space. Very much compact.
8 The battery must be recharged when it is discharged. No such arrangement is required.
9 Commonly employed in cars and light commercial vehicles. Mainly used in racing cars and two-wheelers.
