Choosing The Best High Output Alternator: A Quick Guide

Amperage

All alternators produce a specific level of amperage. Low output units only produce enough amperage to support a vehicle’s electrical system. High output units produce more amperage than what is really needed for most vehicles. However, if you want an alternator that delivers up to 350A, you will need to invest in a brand that is rated “High Output”. These alternators are capable of providing up to 100A at idle speeds. When you compare this high level of amperage to the 50-80A provided by factory alternators, it is no wonder why most auto enthusiasts turn to high output alternators.

Warranty

Since high output, aftermarket alternators are considered top-of-the-line, it is only to be expected that they have a hefty price. However, if you desire a higher level of performance from your vehicle, you will not have an issue spending extra. A factory alternator typically costs less than $100, while high output alternators will run just over $200, depending on the brand. So, when you consider that you are spending more for a much better unit, it is only natural to be concerned about the warranty. With that said, you may be disappointed by the warranty offered by most manufacturers. The standard high output alternator warranty on average lasts about a year. And, if the alternator is utilized for racing, the warranty will not exist after installation.

Installation

Installing an alternator is genuinely not that difficult for experienced mechanics. Factory and aftermarket alternators utilize the same installation process in most cases. However, some units will require an additional ground wire, which may or may not be included in the purchase. To ensure easy installation, be sure to only consider models with an easily accessible ground point and wire.
