Understanding Group Sizes
Battery group sizes dictate physical fit and power output; Costco stocks 15+ common groups, from 24F for Japanese imports to 78 for American trucks.
- Identify your vehicle's group via owner's manual or under-hood sticker - e.g., most Fords use 65.
- Match CCA rating: Costco minimums exceed 500 CCA for reliable cold starts down to -10°F.
- Opt for AGM if your car has regenerative braking; standard flooded types suffice for basics.
- Verify terminal configuration (top-post vs. side-post) in-store with tire center staff.
