Does Costco sell RV batteries?

Costco does sell RV batteries, typically offering lead-acid and lithium-ion options from brands like Interstate, Duracell, and Energizer. These batteries are available in standard group sizes (e.g., Group 24, 27, 31) compatible with most RVs. While stock varies by location, members can check real-time availability using Costco's online inventory tool or mobile app. Pro Tip: Opt for lithium batteries if your RV has solar systems—they provide 3x more cycles than AGM despite higher upfront costs.

Best Lithium Battery Options for RVs

What types of RV batteries does Costco carry?

Costco stocks deep-cycle batteries optimized for RVs, including AGM (Absorbent Glass Mat) and lithium-ion variants. AGM models like Duracell GC2 provide 200+ cycles at 50% DoD, while lithium options such as Battle Born 100Ah deliver 3,000+ cycles with 100% usable capacity.

AGM batteries dominate Costco's shelves due to their affordability ($180–$300 range), but lithium alternatives are gaining traction for long-term ROI. For example, a 100Ah lithium battery weighs 31 lbs versus 60+ lbs for comparable AGM—critical for payload-conscious RVers. Transitional note: While lead-acid remains popular, lithium's weight and cycle advantages make it ideal for off-grid setups. Pro Tip: Verify your RV's battery compartment dimensions before purchasing—Group 31 lithium may require modified trays.

How do Costco RV battery prices compare?

Costco'RV batteries are priced 10–15% below specialty retailers due to bulk purchasing. A Duracell Group 31 AGM costs $249 at Costco versus $289+ elsewhere, while lithium models like Lion Energy UT1300 retail near $899 versus $1,100+ online.

Seasonal discounts occur during spring RV prep months (March–May). But what about warranty terms? Costco extends manufacturer warranties by 12 months for members—a 4-year AGM warranty versus the standard 3-year. Transitional note: While upfront savings are clear, verify return policies—some lithium brands require direct warranty claims.
