Yes, Costco does sell car batteries. You can find them at their in-store Tire Centers, which are available at many, but not all, warehouse locations. The primary brand they carry is Interstate Batteries, a well-known and respected name in the industry. However, availability can vary by location, and installation services are not offered.
Costco's main draw for car batteries is value. As a member, you typically get a competitive price that includes a strong warranty. For example, many Interstate batteries at Costco come with a free replacement period (often 3-4 years) and a prorated warranty for the remaining term. It's a straightforward, no-hassle purchase.
The biggest limitation is the lack of installation. You're buying the battery itself. This is a great option if you're comfortable installing it yourself or have a trusted mechanic to do it. Before making a trip, it's smart to call your local warehouse's Tire Center to confirm they have the correct battery group size for your specific vehicle in stock. For those who need immediate installation, a dedicated auto parts store might be more convenient, but you'll likely pay a premium for that service.
