12V battery ignition versus 6V battery ignition

Until the 1950s the motor vehicle used 6V ignition system since it requires only three cell (of 2V) battery to create 6 Volts system. They are lighter than the 12V battery of same watt-hour capacity. As compression ratio and engine speed increased, the voltage requires to satisfactory ignition of the engine is also increased.

The advantages of 12V ignition system over a 6V ignite is listed below

• The number of accessories can be connected to battery since it giving adequate power supply.
• Improve the starting of engine since twice power is available for ignition during staring.
• Considerably higher voltage is obtained.
• For transmitting same power without excessive voltage drop, the thickness of wire required in 6V system is theoretically two times thicker than the wire used for 12V system.
