Where Is the Cheapest Place to Buy a Car Battery in the US in 2026?
The cheapest place to buy a car battery in the US is usually Walmart for its own EverStart batteries, or Sam's Club for members who already pay the fee. Compare the right group size, cold cranking amps and warranty, then start on ShopBack.

In the US, the cheapest place to buy a car battery is usually Walmart, which sells its own EverStart batteries with no membership fee, or Sam's Club if you already pay for a membership. The cheapest battery is the one that fits your car's group size, meets its cold cranking amps rating and comes with a warranty you can actually use.
The numbers that matter: at the time of writing, Sam's Club lists its Club membership at $60 a year and Plus at $120 a year on its join page, and only Plus includes Tire and Battery Center savings. Walmart has no fee to shop, and its paid Walmart+ membership is optional. The battery market is large: about 130 million car batteries are replaced in the US each year, and about 99% are turned in for recycling, according to figures cited from the US Environmental Protection Agency.
ShopBack US is a cashback site for shoppers in the United States. Start on ShopBack, then shop at the store as usual, and part of what you spend on an eligible online order comes back to you as cash. You can sign up for ShopBack in a couple of minutes before your next order.
Where is the cheapest place to buy a car battery?
There is no single cheapest store for every car; the cheapest place is the one with the lowest total cost for a battery that fits, starts your car in winter and has a warranty you can claim nearby. For most US drivers, that comes down to two stores:
- Walmart for store-brand value with no fee. Walmart's own car battery brand is EverStart, and many Walmart Supercenters have an auto service area. You can order on Walmart.com and pick up in store, which helps when the car still starts but the battery is weak.
- Sam's Club for members. Most Sam's Club locations have a Tire and Battery department, and Sam's Club lists Tire and Battery Center savings as a Plus member benefit. If you already pay the fee for groceries and fuel, Sam's Club is worth checking.
The quick rule: if you do not have a warehouse club membership, start with Walmart; if you already have Sam's Club Plus, compare the same group size and warranty at both. Then add the core charge, any installation cost and the warranty length to the comparison.
Other places that sell car batteries include auto parts chains such as AutoZone, Advance Auto Parts and O'Reilly Auto Parts, and warehouse club Costco, which is on ShopBack US.
Car battery basics: what to match before you compare prices
A cheap battery that does not fit, or does not start the car on a cold morning, is not cheap. Match these three things first.
Group size. The Battery Council International (BCI) group size sets a battery's physical dimensions and the position of its terminals. Your owner's manual or the label on your current battery lists it. A battery in the wrong group size may not fit the tray or reach the cables.
Cold cranking amps (CCA). CCA is the current a battery can deliver at 0 degrees Fahrenheit for 30 seconds while holding at least 7.2 volts. It is the best single measure of starting power in cold weather. Buy at least the CCA your manual asks for. In cold states, more CCA is worth paying for.
Battery type. Some cars, often those with automatic start-stop engines, use an AGM (absorbent glass mat) battery rather than a standard flooded battery. AGM batteries usually cost more. Your manual or the label on the current battery tells you which type you have; if your car came with AGM, replace it with AGM.
Most store websites, including Walmart.com, let you enter your car's year, make and model to filter batteries that fit. Use that filter, then check the group size and CCA on the product page against your manual.
Car battery prices: how to work out the real cost
The shelf price is only part of what a car battery costs. Four other numbers change the answer.
Warranty per year. Store batteries usually come in several lines, with longer free-replacement periods on the more expensive ones. Illustrative example: a $150 battery with a 3-year free replacement warranty costs $50 per covered year, while a $120 battery with a 2-year warranty costs $60 per covered year. The pricier battery is the cheaper buy if you keep the car.
Core charge. Many stores add a refundable core charge when you buy a battery, to encourage you to return the old one for recycling. You usually get it back when you bring in the old battery, so leave it out of your comparison, but do return the core.
Installation. Some stores install batteries, and some charge for it or cannot install in cars where the battery sits under a seat or in the trunk. Ask the store before you buy if you cannot fit it yourself.
Your effective price. For an online order, your effective price is what you pay at checkout minus the cash ShopBack returns. The live rate for each store is on its ShopBack page, so check it on the day you buy.
Car battery best deals in the US for 2026: when prices usually drop
Car battery deals in the US in 2026 are most likely during:
- Black Friday and Cyber Monday. Black Friday 2026 is Friday, November 27, and Cyber Monday is November 30. Auto products often appear in store-wide sales that week.
- Each store's own sales. Walmart and Sam's Club both run their own deal events through the year. Sam's Club Instant Savings, which both membership tiers include, are worth checking before you buy.
- Before winter. Cold weather is hard on weak batteries, because starting power drops as the temperature falls. Having the battery tested in the fall lets you replace a tired battery during a sale instead of paying full price after a breakdown.
The most expensive car battery is the one you buy in a hurry after a no-start, plus the tow. If your battery is more than a few years old and slow to crank, buying ahead on your own schedule is usually the cheapest plan.

Walmart vs Sam's Club car battery: price comparison in 2026
Walmart and Sam's Club are both owned by Walmart Inc., and both are good places to buy a car battery, for different shoppers. Compare the same group size, CCA and warranty at both on the same day, and add any membership fee you would not pay anyway.
Where Walmart is strong. No membership is needed to shop, and EverStart is Walmart's own battery brand. Walmart+ is optional at $98 a year or $12.95 a month and includes a fuel discount of up to 10 cents a gallon at participating stations, according to published details of the programme; check Walmart's own Walmart+ page for the current list. You can order on Walmart.com for pickup, which keeps the purchase online.
Where Sam's Club is strong. Sam's Club is a membership warehouse club. At the time of writing, its join page lists Club at $60 a year and Plus at $120 a year. Both tiers include Instant Savings, member-only fuel prices and a 100% Satisfaction Guarantee. Plus adds Tire and Battery Center savings, free shipping on orders over $50 and early shopping hours.
How to choose. If you do not have a Sam's Club membership, the $60 to $120 fee is usually more than any saving on one battery, so start with Walmart. If you already have Plus, check whether the Tire and Battery Center savings beat Walmart's price for the same group size and warranty.
| Walmart | Sam's Club | |
|---|---|---|
| Membership to shop | None needed; Walmart+ optional at $98 a year or $12.95 a month | Club $60 a year; Plus $120 a year (join page, at the time of writing) |
| Own battery brand | EverStart | Check the club's Tire and Battery department |
| Battery perks | Order online for in-store pickup | Plus includes Tire and Battery Center savings |
| Other relevant perks | Walmart+ fuel discount of up to 10 cents a gallon at participating stations | Member-only fuel prices; 100% Satisfaction Guarantee |
Walmart and Sam's Club: the official programmes that lower the price
Each store runs its own programme, and these are the first step in getting the lowest price.
Walmart+. Walmart's paid membership costs $98 a year or $12.95 a month. It includes free shipping on items sold or shipped by Walmart.com and fuel discounts at participating stations. For one battery, it rarely pays for itself; for a household that already orders from Walmart every week, it often does.
Sam's Club Club and Plus. Sam's Club lists two yearly tiers on its join page. Club, at $60 at the time of writing, includes Instant Savings, member-only fuel prices, Scan and Go and free curbside pickup. Plus, at $120, adds Tire and Battery Center savings, free shipping on orders over $50, free delivery from the club on orders over $50, early shopping hours and pharmacy and optical savings. If you service your car at Sam's Club, Plus is the tier the battery perks sit in.
Where ShopBack fits before you buy a car battery online
ShopBack works like an automatic cash discount on your online order. Start on ShopBack, then shop at the store as usual. Cashback lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles.
A car battery is heavy, so most people buy it online for store pickup rather than shipping. That still counts as an online order, which is what ShopBack tracks. Illustrative example: on a $150 battery at an illustrative 3%, $4.50 comes back, so the effective price is $145.50. The real rate is different for each store and changes over time, so check the live rate on each store's ShopBack page: Walmart and Sam's Club. Walmart works differently: ShopBack pays a fixed cash amount on eligible Walmart orders, so your effective price there is what you pay at checkout minus that amount; the live amount is on Walmart's ShopBack page.
Each store has its own terms, and for car batteries they matter:
- Sam's Club. Product categories and services can be treated differently. Read the Terms and exclusions section on ShopBack's Sam's Club page before you count on cash back for a battery order.
- Walmart. Promo codes from outside ShopBack can stop an order from tracking. If you use a code, use one featured on ShopBack's Walmart page.
- In-store purchases. A battery bought at the counter without an online order does not go through ShopBack. Order online first, then pick up.
The routine is the same at every store:
- Find your group size and CCA, and pick the store.
- Open that store's page on ShopBack US and tap through to the store.
- Order online in the same session, for pickup or delivery.
- Return your old battery to get the core charge back.
Frequently asked questions
Where is the cheapest place to buy a car battery?
In the US, the cheapest place to buy a car battery is usually Walmart, which sells its own EverStart batteries, or Sam's Club if you already pay for a membership. The cheapest battery is the one that fits your car's group size, meets its cold cranking amps rating and comes with a warranty you can use. Compare those first, then start on ShopBack before you order online.
Is a car battery cheaper at Walmart or Sam's Club?
It depends on whether you already have a Sam's Club membership. Walmart has no membership fee and sells its own EverStart batteries. Sam's Club lists its Club membership at $60 a year and Plus at $120 a year at the time of writing, and Plus includes Tire and Battery Center savings. If you would join only for a battery, the fee usually cancels out the saving.
What is EverStart?
EverStart is Walmart's own brand of car batteries. Like other store brands, it comes in different lines with different warranties, so compare the warranty length and cold cranking amps rather than the brand name.
How do I know which car battery fits my car?
Match the group size and the cold cranking amps. The Battery Council International group size sets a battery's physical dimensions and terminal layout, and your owner's manual or the label on your current battery lists it. Most store websites also let you enter your car's year, make and model to filter batteries that fit.
What does cold cranking amps mean?
Cold cranking amps, or CCA, is the current a battery can deliver at 0 degrees Fahrenheit for 30 seconds while holding at least 7.2 volts. It measures how well the battery starts an engine in the cold. Buy a battery that meets or exceeds the CCA your car's manual asks for, especially in cold states.
What is a core charge on a car battery?
A core charge is a refundable fee many stores add when you buy a car battery, to encourage you to bring back the old one for recycling. You usually get it back when you return your old battery, so it is not part of the real price. Check the store's own policy for how long you have to return the core.
When are car batteries cheapest in the US?
Car batteries usually go on sale during big retail events such as Black Friday on November 27, 2026 and Cyber Monday on November 30, 2026, and during each store's own sales. A battery is often an urgent buy, though, so the cheapest move is usually to test your battery in the fall and replace it before it fails rather than paying for a tow.
Does a Sam's Club membership pay for itself on a car battery?
Usually only if you shop at Sam's Club for other things too. At the time of writing, Sam's Club lists Club at $60 a year and Plus at $120 a year. Add the fee to the battery price unless you would pay it anyway, then compare with the same group size and warranty at Walmart.
How does ShopBack make a car battery cheaper?
ShopBack works like an automatic cash discount on your online order. Start on ShopBack, then shop at the store as usual, for example ordering the battery on Walmart.com for pickup. ShopBack pays a fixed cash amount on eligible Walmart orders, so your effective price is what you pay at checkout minus that amount; the live amount is on Walmart's ShopBack page.
Is cashback the same as store points?
They work differently. Cashback lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles. Store programmes such as Sam's Club membership rewards run under their own terms.
