Yes, Costco sells AGM (Absorbent Glass Mat) batteries, including specific models like the Yuasa YUAM320BS YTX20L-BS Maintenance Free AGM Battery for motorcycles. These batteries are designed for durability and maintenance-free operation, with features like spill-proof construction and vibration resistance. However, availability may vary by location, and product lines often focus on automotive or mobility applications rather than general-purpose options. Pro Tip: Check Costco’s online inventory or contact your local warehouse for real-time stock updates on AGM batteries before visiting.
What AGM battery models does Costco offer?
Costco currently lists the Yuasa YUAM320BS motorcycle AGM battery priced at $94.97. This model includes an acid pack and delivers 310 cold cranking amps (CCA) for reliable starts. Key specs: 12V system, 18Ah capacity, and 6.9 lbs weight. While primarily marketed for motorcycles, it’s compatible with ATVs and small marine applications. Transitioning to automotive needs, Costco’s AGM selection appears limited compared to specialty battery retailers. For example, this Yuasa model uses advanced calcium alloy grids that reduce water loss by 80% compared to conventional lead-acid batteries. Pro Tip: Always verify terminal orientation (L-shaped vs. straight) before purchasing replacement batteries.
How do Costco’s AGM prices compare to competitors?
Costco’s AGM batteries typically cost 15–20% less than auto parts stores. The Yuasa motorcycle AGM at $94.97 undercuts Amazon’s $112 listing for the same model. Price advantage comes from bulk purchasing power and limited SKU selection. For automotive AGMs, competitors like Interstate Batteries offer broader voltage options (6V/12V/24V) but at 25% higher average prices. Consider this comparison:
| Retailer | AGM Type | Price |
|---|---|---|
| Costco | Motorcycle | $94.97 |
| AutoZone | Automotive | $229+ |
Practically speaking, Costco’s AGM offerings make sense for motorcycle/ATV owners but lack heavy-duty automotive options. Why pay more elsewhere? For standard applications, the value proposition holds—just confirm compatibility first.

Are Costco AGM batteries rechargeable?
Yes, but use smart chargers maintaining 14.4–14.6V absorption phase. Overcharging above 15V permanently damages AGM cells.
