How to Check If a Car Battery Is Under Warranty

Having a warranty on all different aspects of your car can end up saving you quite a bit of money in the long run. You may be wondering how to check if a car battery is under warranty. Maybe it’s a new car or maybe you’ve had it for a while and can’t quite remember but this is where we come into the equation.

You can check whether your battery is still covered under warranty by locating a small sticker on the battery that will show the month and date your battery was manufactured. If you aren’t able to find that sticker there will also be a 4-digit code stamped on the battery that will show you the month, year, and plant that it was manufactured in – most batteries are covered under warranty between 1-4 years.

Let’s take a look at how to know if you’re covered but also all the things that could go wrong that would be covered under this warranty.

What Is a Warranty and Why Do You Need It?

To put it simply, a warranty will ensure you don’t have to pay for any repairs if something goes wrong with your battery. But there will be some terms and conditions to it.

This can cover an array of things from manufacturing errors, to damage, or if it simply won’t hold a charge. All of these things tend to be covered under your warranty which will save you the extra unnecessary stress of whether you can afford to replace your battery after you’ve realized it’s not doing its job correctly.

A singular car battery can have many different warranties that cover different things. Retailer and manufacturer are the two most common although if your vehicle is new, a new car warranty might also be in place.

Is Your Battery Still Covered?

The easiest way to check if your battery is still covered is by checking the battery itself. Now there are a huge number of ways that your battery could be date stamped and we are going to look at a few here.

Open up your hood and locate your battery, here you should be able to find a small sticker with a date printed in M/YY format. For example, if this sticker says 4/16 then this would mean your battery was manufactured in April 2016. It may also consist of numbers and letters. The letters would be the month and the numbers would be the year.

Be sure to keep any receipts when you purchase a new battery as this will ensure you can claim your warranty. Most batteries are covered anywhere from 1 to 4 years but a retailer warranty will be added on top of this.

If you can’t seem to locate the sticker then take a look for a four-digit code. It will usually begin with a P or S with the following two digits representing the month, then the year, and lastly the plant in which it was manufactured. This is a great way to help you figure out if you’re still covered under warranty if you can’t find that handy little sticker.

Here’s a quick video to show you the different ways batteries are date stamped

What’s Included in a Standard Warranty?

What’s covered under your warranty will vary depending on which company you choose to go with but many of the standard things will be covered under most.

The most basic thing you will be able to claim under most warranties is any damage that was caused due to a manufacturing error. This can be caused by workmanship or simply the materials used for that specific battery.

Warranties tend not to cover things like:

  • Sulphation happens when your discharged battery is left to stand for a prolonged period of time.
  • Wear and tear due to daily use.
  • Deep cycling.
  • Overcharging causes electrolytes to evaporate due to extreme heat.
  • Physical damage.
  • Incorrect application.

Warranties won’t cover anything that was caused due to consumer fault.

Are There Different Warranties Available?

There are certainly different warranties available depending on what you’re looking for. Every different manufacturer’s warranty will look slightly different from each other as they are all trying to offer you something different so simply take a look at all your options.

Here are some of our favorites!

Costco Car Battery Warranty

Costco offers a brilliant warranty that will cover your battery for up to 36 months. This is, unfortunately, a limited replacement warranty meaning if the damage caused was in any way your fault then you might not be able to claim so always double-check the terms and conditions.

Walmart Battery Warranty

You will need to find a Walmart with an auto shop attached in order to claim your warranty. Here the technician will check whatever the issue is with your battery and they conclude whether or not you are covered under your warranty.

Most of the company’s batteries are covered for up to 3 years but if you’re interested in a specific model’s warranty then head to their website where all the necessary information is listed.

Autozone Battery Warranty

Autozone is a great place for all your car needs including your battery warranty. Not only can you purchase new batteries but they will also take your old batteries and dispose of them correctly. Although they do offer this great service, their warranty is rather strict when compared to others.

If you do need to get a new battery due to an error on your current one then you will not receive either a refund or exchange, instead, you will be given a credit. This credit can then be put towards a new battery but there is no guarantee it will cover the price of a replacement.

Amazon Battery Warranty

Amazon offers many name-brand car batteries but due to the fact they come from different sellers, warranties will vary. The description will have any details you need about what’s covered and what isn’t but if you have any extra questions then you can always contact the seller.

Amazon is a brilliant and convenient way to shop with many products to choose from and incredibly quick shipping.

How to Claim Your Warranty

Simply take your battery back to the retailer you purchased it from as soon as you notice any issues. You will need the receipt from when you purchased it as well as an idea of how old it is. A technician will then take a look at any issues and decide if you are covered under your warranty.

From there if it is decided you are then you will either receive a refund or an exchange for a new battery.

Conclusion

So as you can tell, it’s pretty simple to check whether your battery is covered under warranty. Take a look at that little date sticker and you should be able to figure out whether your warranty is still in date.

Remember that consumer-caused faults tend not to be covered under most warranties and receipts from purchases are required. Take a look at some of our favorite warranty providers listed above!

Battery Fitting Mistakes

Can you fit your own battery? You sure can. But you should know three common battery fitting errors.

1 Removing car’s computer power – Some cars won’t like to have their batteries removed. It causes the computers to lose track of the sensors they use to manage various systems.

2 Connecting a battery up backways – This is a really common issue and can be spendy to fix.

Anyway, we will avoid these common issues because we will follow some basic battery fitting tips.

3 Failing to calibrate the Battery control module

1 Removing the car’s computer power

This doesn’t tend to be an issue with regular family cars, but the more sophisticated the car, the more computers, and the more likely removing the battery will cause issues.

What type of issues? Mostly irritating type stuff like inop HVAC systems or erratic window controls and poor quality gear changes. And in most cases, these issues fix themselves by just driving the car. (my favorite type of problem)

But sometimes, you have an erratic idle that won’t fix itself and may require a visit to a dealer to set it straight again.

I advise folks who are going to change a battery to use a KAM (Keep Alive Memory) tool; it sends a small voltage to the car’s computers to keep them alive while the battery is disconnected.

2 Connecting up the battery backways

In many cases, connecting up backways just blows a fuse, no biggie, right? And hooking up backways is an easy mistake to make, and it often stems from trying to fit a battery that isn’t suitable, poles on the wrong sides, etc.

But for some unlucky folks hooking up backways can result in some spendy repair bills.

I wrote a post about hooking up your battery backways, and you can check that out here – “Battery sparked now won’t start.”

I also wrote a post about battery terminal identification, and you can check it out here Unmarked car battery terminals.

3 Battery Control Module

Modern vehicles use a computer specifically to manage your battery health; when you replace the battery, the battery control module (computer) should be calibrated – You tell the computer, ” Hey, I’m a new battery, and you don’t need to charge me at the same rate you did the old battery.

If the control module isn’t notified of the battery change, it may overcharge your new battery, which will shorten its life. Anyway, I wrote a post about swapping out your battery, it covers all of the above in more detail, and you can check it out here – “How hard to change a car battery?

The Best Place To Buy a Car Battery

Finding yourself in need of a new car battery can be frustrating, so knowing ahead of time where to shop for the best price can be a big help.

In this article, I’ll take a close look at a few of the best places to buy car batteries. You’ll find and information for Advance Auto Parts, Costco and NAPA among others. I visited each of the stores’ websites to see current on car batteries, the length of warranties and whether the installation is included in the purchase price.

Where To Buy a Car Battery

When it comes to deciding where to buy a car battery, there are a few things to keep in mind: Make sure that you’re shopping for the right size battery, be sure to compare prices, familiarize yourself with the warranty and see if the installation is included. You should also take the time to check the ratings and reliability of a certain brand or battery model before buying.

If you do all those things, you’ll likely find the best deals on car batteries at a store near you instead of at online retailers. On top of great prices, you’ll also typically find longer warranties (compared to online stores) and free installation.

I’ve found that Costco, Walmart, Sam’s Club and Advance Auto Parts are great places to buy a car battery. AutoZone and NAPA are also worth checking out!

Below, you’ll find more detailed information on these retailers including where to find the best price.

The Top 6 Places To Buy a Car Battery

To see where I could get the best overall deal, I compared the prices, warranties and installation fees for similar lead-acid 24/24F car batteries. This size battery fits several Acura, Honda, Infiniti, Lexus, Nissan and Toyota models including the car I drive.

Here’s what I found in December 2022.

BrandPriceWarrantyInstallation

Warranties may vary based on the original date of purchase.

As you can see, you’ll have access to low prices, reliable warranties and free installation at stores you can visit in person.

Overall, I found the lowest overall price at Costco. However, Costco doesn’t offer installation, which means I’d either have to install it myself or pay to have it installed somewhere else. But Walmart will install a car battery, no matter where you buy it for only 15.

Walmart offered the second-lowest price including free installation and a great warranty. Plus, you can use your Walmart rewards card to get 5% cash back by ordering the car battery online.

Sam’s Club offered the next-best deal. followed by NAPA, Advance Auto Parts and AutoZone.

You can also find a wide variety of car batteries at Amazon for reasonable prices, but you won’t get the best deal. The warranties vary by battery, and in many cases, they aren’t valid because you’re buying through Amazon instead of a dealer certified by the manufacturer. And of course, installation is not included.

For the best overall deal, be sure to check out these top six places to buy a car battery.

Costco

Price Range: 109-179 Available Brands: Interstate

If you’re a Costco member, you won’t be surprised to hear that this is where you’ll find some of the lowest on quality car batteries. Costco carries only Interstate Batteries. which are highly rated in several sizes and models by Consumer Reports (subscription required).

While you can’t order a car battery online from Costco, you can use the store’s online battery finder to see which batteries will fit your car and how much they cost. From there, you can visit your nearest Costco to make your purchase.

Costco offers a 36-month limited warranty on most batteries. but unfortunately, you won’t be able to get your battery installed here. Again, keep in mind that Walmart offers installation for batteries bought elsewhere for only 15. That still means you’ll most likely be saving big with this purchase compared to the at stores with free installation.

Walmart

Price Range: 59-215 Available Brands: EverStart and Optima

Based on my research, Walmart offered some of the lowest in addition to great warranties and free installation if you buy your battery from the same location. Be sure to make your purchase online and use your Walmart rewards card for an additional 5% cash back.

You’ll mostly see EverStart car batteries at Walmart. That brand has several models that get high ratings from Consumer Reports. EverStart Value automotive batteries are available from 59 and up.

To get started, visit the website and enter your car make, model and year. This will filter your results by batteries that will fit. From there, you can browse the selection and order the battery online to be picked up in-store nearby.

Sam’s Club

Price Range: 102-238 Available Brands: Duracell

Sam’s Club is a good place to find car batteries at a good price, but of course, you have to be a member. The warehouse carries Duracell brand batteries, which Consumer Reports labeled “Best Buy” options.

Sam’s Club locations with Tire Battery centers offer free car battery installation. Batteries are also covered by a free replacement warranty for three years from the date that you buy them.

While the car batteries are available only in-store, you can still browse the available selection online. This is a great way to compare prices, read reviews, and check availability.

Advance Auto Parts

AutoZone

Price Range: 79-528 Available Brands: Duralast, ACDelco, Optima and more

Final Thoughts

If you’re a Costco or Sam’s Club member, you’ll likely find the best deals on car batteries at your favorite warehouse store. If not, Walmart is a great place to shop for car batteries. All three retailers offer three-year warranties, and the latter two offer free installation.

Additionally, you can find some of the lowest total on car batteries at Advance Auto Parts if you use promo codes. Also, remember to collect your 22 refundable core charge.
