Frequently Asked Questions

Heavy-duty alternators are not necessary for stock vehicles unless you intend them for purposes that need additional horsepower. The factory alternator your vehicle came with provides sufficient power for all your vehicle’s necessities like headlights, air conditioning, and so on, so unless you’re anticipating high energy demands, replacing an old alternator with a new equivalent is perfectly fine. If you have a heavy-duty vehicle or if you want or need to enhance a light-duty vehicle, a high-output alternator like a truck alternator will do the job.

A heavy-duty alternator should have a reading between 13.6-14.2V while charging if it is in working order.

Alternators for sale vary in price depending on the type of vehicle it’s for and the output of the alternator. In South Africa, an alternator can cost anywhere from R1500 to R4000.
