Remanufactured vs New Alternators

Which one is better or last long between a remanufactured and new alternator has been a subject of great debate and confusion over the years. Some people think remanufactured alternators are second-hand, while others believe it is close to the new alternator in appearance and performance. It’s wise to also bear in mind the alternator repair cost.

Typically, remanufacturing means all broken and worn-out parts have been taken off and replaced with new ones. This process does not take away the durability feature of the final product (and once you consider how long does it take to replace an alternator). You could also check out our guide on how long should an alternator last and how long do alternators last.

For instance, if the thread of your tires wears out, you only remove them and replace them with new ones while you use the same wheel. The exact process happens with a remanufactured alternator but involves incredible complexity and standards. New alternators have their advantages too, but remanufactured ones are not inferior even in price or performance.

Signs Of Bad Alternators

Typically, alternators are designed to last a long time. However, they can shut down if you don’t properly charge them. Knowing where the fault comes from is always difficult when alternators shut down. You will have to find out whether the battery is faulty or it’s the alternator.

Start the car, disconnect the battery terminals, and watch if the vehicle will keep working or go off. If it goes off, it means your alternator is faulty. A faulty alternator also produces annoying noise. Additionally, a dim headlight in your car is a sign of a damaged or faulty alternator. Take note of all these so you can easily know when to replace your car’s alternator.

Frequently Asked Questions

Here are some popular frequently asked questions about the best brands of alternators…

How Much Is A Car Alternator

Generally, prepare to spend about $180 to $1000 for a quality alternator. The prices of car alternators vary due to your make and model of car, the brand of alternator you want, the size, and the amount of amp output your car needs. Remanufactured alternators are cheaper, while new alternators that produce high amps for new cars are expensive.

What Alternator Fits My Car

Figuring out which alternator your car needs involves finding out the total electrical load of your vehicle. The best way to find out the entire electrical load of your vehicle is to use an ammeter. Charge your car battery and switch off the engine, connect the ammeter in series to the battery’s ground terminal, and then start turning each car accessory on and off. Note down each amperage draw, and when you are done, add up the figures of amperage draws of all the accessories. Your car’s alternator must provide 50% output higher than the figure you got from that calculation. Also, if you don’t have an ammeter, you can get the electrical load of your car by checking the accessory fuses. Once you figure this out, you can choose the brand, size, and color you want.

Are Remanufactured Alternators Good

A remanufactured alternator has undergone several tests. Manufacturers would have replaced the voltage regulator, brushes, rotors, and every other part that needs replacement. A remanufactured alternator looks just like new and is in good condition, its materials are 100 percent OE material, and in most cases, they are better than a brand-new knock-off. With remanufactured alternators, experts would have corrected every shortcoming in the OE. Also, remanufactured alternators are mostly cheaper.

Where To Buy Alternators

You can drive into a local auto shop, tell them what you need, and they will get you the alternator that your car needs. You can also get alternators from a dealership. They know everything your car needs and are the perfect ones to help you select a new one for your car. You can order the alternator from a trusted online auto shop if you know what you want. They will bring it to your doorstep and help you install it. You need to understand that wherever you visit to get the alternator will affect the price significantly.

How Long Does A Rebuilt Alternator Last

A rebuilt alternator can last up to 80,000 to 150,000 miles. Sometimes it lasts longer than a new knock-off because manufacturers would have made certain upgrades based on the complaints people made about a new one. Using and maintaining your alternator also affects the new or rebuilt price.

Are Ultima Alternators Any Good

Altima alternators are some of the best-remanufactured alternators in the auto industry. They provide exceptional quality, unbeatable output, and are durable.

Who Makes The Best Alternators

Several brands produce alternators, and some stand out among them. DB Electrical has quality alternators for Chevrolet, GMC, Buick, Hummer Cadilac, and Saab. DB Electrical AFD0012 and DB Electrical ADR0368 are one of the best in the market. Another brand that produces top-notch alternators is Remy; their alternators are durable and can work with different vehicles. ACDelco alternators are also one of the best in the market, with high voltage and amp output, an internal fan, and a two-year warranty on their alternators. You can’t be wrong with Tuff Stuff alternators. Their alternators produce power that exceeds OEM, the coils are made from heavy-duty copper, and they have excellent energy efficiency.

Will A New Alternator Improve Performance

Installing a new alternator to your car means replacing the old one with a better and higher amp one. A new alternator will improve your vehicle’s performance. Every accessory and car part that has stopped working or is functioning slowly will begin to perform at the highest level. Once you get the right one for your car, you can be sure of a better performance.

What Makes A High Amp Alternator Better

Most factory alternators can only produce 65 to 100 amps of output which is only enough to power basic car electronics. For instance, if you decide to install a high-voltage stereo in your car, you will need to install an alternator that can power that stereo and other car accessories. This is where high alternators come in. You should note that a high amp alternator won’t spoil anything in your car, no matter how high it is. Your car accessories will only get the required amperage from the alternator.

Do You Need A New Battery Or Alternator

In most cases, the issue is always with the alternator. If your car starts, but certain components or accessories won’t work, your battery is good, but the alternator is faulty. Get a new alternator, and every part will start functioning at its best.


Many auto brands produce new and remanufactured alternators. Knowing which brand is the best for your car is very important. Most alternators are vehicle specific; recheck the article and choose which one is best for your car.
