Difference between Battery Ignition System and Magneto Ignition System?

Battery Ignition System:

1. The Battery Ignition System and the Magneto Ignition System are two ways that an engine can be started. 
2. A battery Ignition System uses a Battery to ignite the air/fuel mixture inside a combustion chamber. 
3. The battery is connected to a system that produces an electric current inside it, which increases with RPM or Revolutions Per Minute of the engine and finally ignites the mixture of air and fuel inside a combustion chamber. 
4. The battery used for this system is a 12 Volt Battery which powers a coil that produces electric current inside it resulting in ionization or sparking of air/fuel mixture. Battery Ignition System is easy to install on older vehicles because manufacturers already have Battery, Coil, and Starter installed on their vehicle from production. 
5. A battery Ignition System is also used in electric vehicles.
6. The Battery Ignition System is more common, mainly because it is easier to use. 
7. All you need to do is connect the battery to the ignition system and turn on the switch. 
8. The Battery Ignition System has a higher voltage than the Magneto Ignition System, which means that it can create more sparks. 
9. The battery Ignition System will cause the engine to run more smoothly and start better. 
10. The Battery Ignition System is great for small engines, it also makes starting easier in cold weather because the Battery Ignition System’s high voltage causes a faster burn rate of the fuel mixture.
11. The Battery Ignition System has a limited amount of power, so if you were to use too much of the Battery Ignition System’s power, you would just have to recharge the battery. 
12. The Battery Ignition System gets its power from combustion inside of the engine that is already running, the Battery Ignition System will get charged and not be at 100% power. 
13. It is impossible to test Battery Ignition Systems while they are installed on an engine because the Battery Ignition System needs a load on it for it to draw enough current to test properly.
14. Battery ignition delivers electricity to the spark plugs directly – magneto sends energy via an ignition coil; this system is hampered by the fact that there are always fluctuations in power leading to poor engine performance.
15. The Battery Ignition System also needs a good connection to the spark plugs to work properly, if the connection is bad then the Battery Ignition System will not work.
16. The Battery Ignition System is more used for having a higher voltage. 
17. If you are running on battery, you can still rely on your starter-generator to kick in and power up an alternator which will produce enough current for your lights and wipers. 
18. Battery Ignition Systems use cells that produce a current. The cells are turned on and off by another set of points or systems, such as the breaker points in an older car. More modern vehicles have the “converter” to regulate the high voltage electricity from the battery to a lower level which is safer to flow through a wire harness and control system.

Magneto Ignition System:

1. Magneto Ignition System uses magnets to produce an electric current which then ignites the air/fuel mixture inside a combustion chamber.
2. The Magneto Ignition System does not have limited power like the Battery Ignition System.
3. Magneto Ignition System does not need to be recharged. 
4. Magneto Ignition System does not have any moving parts. The Battery Ignition System has moving parts, which can wear out over time. 
5. Magneto Ignition Systems use permanent magnets powered by household alternating current, created using a generator driven by your engine’s crankshaft or accessory driveshaft power source, for ignition purposes only.
6. The Magneto Ignition System is more reliable than the Battery Ignition System.
7. The Magneto Ignition System does not have these problems. It will always have the same amount of power, so you don’t have to worry about recharging it. 
8. The Magneto Ignition System is also easier to test because you can just attach a spark tester to the spark plug wire and spin the engine. This is not possible with Battery Ignition Systems because you need to have the engine running to get a reading from the Battery Ignition System.
9. The Magneto Ignition System is better but is not as widely used because it is harder to use and you need a Battery Ignition System to test it.

Conclusion of A Battery Ignition System and Magneto Ignition System:

A battery ignition system results in an electronic spark being generated via a circuit where one terminal is at ground potential, with the other terminal connected to an output lead for delivering high voltage pulses to the electrodes of the engine’s sparking plug. Conversely, a magneto produces its own voltage through mechanical means by spinning rapidly inside a magnetic field – it does not need external power because all energy is produced mechanically within it.

A battery ignition system works better because it can deliver a continual, powerful charge at all times, whereas a magneto has trouble delivering strong charges due to natural fluctuations in power supplies. Essentially, impulses from magnetic systems are unreliable compared with the direct voltage input of batteries. 

The ability to keep operating whilst running solely off of a battery gives it an edge over the unreliable magneto. 

It takes more time, but it’s usually not hard at all with some persistence. Keep in mind that if you’re stuck somewhere without a car charger or jumper cables to turn your car’s engine over once every five minutes so as not to drain its fuel tank any faster than necessary….
