Does a high output alternator have a shorter lifespan?

The high output alternators should last you a good while, but the more current your alternator produces, the faster it may wear out. An alternate always working on its peak capacity will die out quicker, so it all depends on your usage and the electrical load.

How to clean an alternator?

Never go with petroleum-based engine degreasers for cleaning your alternator, and never utilize a pressure washer or compressed air for cleaning, too. Stay away from cleaning agents or spraying degreasers straight into air inlet openings on your alternator. Dilute your degreaser to a fifty-fifty mixture with water before you apply it with a cloth or spray it very gently.

What can be damaging for my alternator?

Driving your vehicle through water deep enough to flood or splash the alternator could damage its shaft bearings and the brushes, along with the electronics inside. Water can cause corrosion, which over time damages the wiring inside.

Buying Guide

Here is a quick buying guide to help you further.

Electrical Load

How much electrical load is your vehicle carrying? Understanding this will help you realize how strong the alternator should be to give power to it all.


Amperage is the max volume of electricity the alternator can produce. If the vehicle’s electrical load crosses the alternator’s amperage, then it is troublesome.

The Fit

Always check through the company’s catalog that the alternator you are choosing fits your vehicle or not. You cannot grab any alternator and call it a day. Some units are only for certain types of cars.


We understand how easy to take other’s advice for choosing alternators, but the best way is to trust your instinct and do proper research. Make your own decision and see what works best for your usage. As the market brims with so many options, we hope our list of some of the best units helps you make the right choice. Only opt for trusted brands and always steer clear of any frauds that could risk your vehicles. Happy riding!
