While your engine needs petrol or diesel in order to operate, even a full tank of fuel won’t do you any good if the electrical system fails. Your engine uses electricity to create the spark necessary to ignite fuel for combustion. That electricity is initially generated by the car battery (on initial cranking), and then by the alternator. The car electronics pull their power from the alternator once the engine is cranked and running, but will pull power from the battery when the engine is off but the switch is on or in accessory mode. Quickco provides car batteries, alternators and other electrical system components designed to work with your specific make and model. It’s essential that you have the right battery and alternator, as an incorrectly rated component can cause serious problems, or not fit at all (in the case of an alternator). All of our electrical system components offer OEM fit and functionality for durability and longevity.
