OEM Alternators

The alternator converts mechanical energy from your engine’s crankshaft to electrical energy in the form of alternating current (AC). Through the alternator’s rectifier, AC is converted to DC, which is then used to charge your car’s or truck’s battery.

Why Your Car’s Alternator Is Crucial

Without your vehicle’s alternator working as intended, your car’s battery won’t be recharged once its energy is depleted, or it could also become overcharged, which can be worse. In the case of a depleted battery, you’ll have trouble starting the engine or turning on your vehicle’s lights. And when the battery is overcharged, it can lead to heat buildup, gassing, and damage to the battery.

Does an Alternator Have to Be OEM?

If you’re faced with replacing the alternator, using OEM alternators is the best course of action. This ensures that you’re getting the maximum level of quality, reliability, and performance. Some aftermarket alternators are also remanufactured or “reman” alternators, which means they were simply taken apart and then rebuilt with a few new parts.

How Long Does an OEM Alternator Last?

Using an OEM alternator for your vehicle also means it will last longer, and in some cases last the entire lifespan of your vehicle. Some original alternators last upwards of 150,000 miles.
