How Many Volts Lawn Mower Battery Should You Choose?
One common question from lawn mower owners is, "How many volts does a lawn mower battery have?" Well, the voltage of a lawn mower battery can vary depending on the type of mower you have. Traditional gas-powered lawn mowers typically do not have batteries, as they rely on a pull-start mechanism.
Ignition Coil Basics
When the points open, the flow of primary current stops and the magnetic field collapses. This sends current through the secondary winding. The coil becomes a transformer, stepping the voltage up. If your car uses a 12 volt battery, the 12 volts you put into the primary side of the coil will exit the secondary side as 30,000 volts!
