Yes, Costco does sell car batteries. They are a popular destination for battery purchases, primarily offering products from the reputable Interstate Batteries brand. You can find them in the tire center section of most Costco warehouse locations. The key advantage is competitive pricing for members, often including a strong warranty and free installation.
However, availability can vary by location. It's not a self-service item; you need to go to the tire center counter for assistance. They will typically test your current battery and electrical system for free before recommending a replacement. This is a valuable service to ensure the battery is the actual problem.
The main benefit is the value. Costco's batteries are known for their long prorated warranty periods. For example, you might pay a lower upfront cost but get a 36-month free replacement warranty, followed by a prorated credit. The free installation saves you a trip to a mechanic and the associated labor cost.
The primary limitation is selection. You'll usually find a range of standard lead-acid batteries for common vehicles, but options for specialty cars, like some European models or vehicles requiring Absorbent Glass Mat (AGM) batteries, might be limited. It's always best to call your local warehouse ahead of time to confirm they have the correct battery for your car's make, model, and engine size.

Absolutely. I just bought one there last month for my SUV. You have to go to the tire center, not the main aisles. The guy tested my old battery for free, confirmed it was dead, and had a new Interstate battery installed in about 15 minutes. No extra charge for the labor. The price was definitely better than the auto parts store down the street, and the warranty is solid. Just make sure you have your membership card with you.

They do, but it’s not like picking one off a shelf. You need to go to the Tire Center. The selection is pretty much just Interstate brand, which is fine for most cars. The big plus is the free installation. The downside is that if you drive an older or less common car, they might not have the specific size or type you need. I’d recommend calling your local store before you go to check their inventory for your vehicle.
