What electrical components put the biggest load on the battery? Patrick
The demand load on any electrical component determines how thick its supply cable must be. So take a look. The biggest electric power guzzler - by far – is the starter motor. Its supply cable is as thick as an adult’s forefinger (most other wires are as thin as a pencil lead). The starter can draw up to 300 amps (3.6 kilowatts). That is the same as three dozen 100W headlamps on full beam!
