What Types Of Batteries Are Sold At Costco?
Costco sells specialized AGM (Absorbent Glass Mat) and lithium-ion batteries through its Amazon marketplace partners, primarily designed for powersport applications like motorcycles, ATVs, and snowmobiles. Key products include Yuasa AGM batteries (e.g., YUAM320BS, YTZ7S) offering maintenance-free operation, and Mighty Max AGM/GEL batteries (e.g., YTX14L-BS) with spill-proof designs. Lithium options like NOCO NLP20 and LiFePO4 packs (400-480 CCA) provide lightweight, high-cranking power for Harley Davidson, Kawasaki, and Honda vehicles. Most batteries feature 12V configurations with capacities ranging from 3Ah to 19Ah.

What AGM batteries does Costco offer?
Costco’s AGM lineup emphasizes YTX-series powersport batteries like Yuasa YTX20L-BS (12V 18Ah, 310 CCA) and Mighty Max YTX14-BS (12V 12Ah, 200 CCA). These sealed lead-acid batteries use absorbed electrolytes to prevent leakage, ideal for vibrations in motorcycles. Pro Tip: AGM batteries retain charge 3x longer than flooded types during seasonal storage—rotate terminals monthly to prevent sulfation.
Models like ExpertPower ETX14-BS (14Ah) demonstrate Costco’s focus on OEM-compatible replacements. For example, the YTX14-BS fits Kawasaki Ninja 650 and Yamaha YZF-R6, delivering 200 cold cranking amps for reliable cold starts. Warning: Never charge AGM batteries above 14.6V—use smart chargers with AGM-specific profiles to avoid grid corrosion.
Are lithium batteries available at Costco?
Yes, Costco stocks lightweight LiFePO4 lithium batteries like NOCO NLP20 (12V 7Ah, 600A) and KEMIMOTO YTX14-BS (12V 6Ah). These offer 50% weight reduction versus AGM, with 2000+ cycle lifespans. Real-world example: The YTZ10S LiFePO4 battery (12V 6Ah) starts Harley Davidson Sportsters 20% faster than OEM lead-acid units.
| Parameter | AGM | Lithium |
|---|---|---|
| Weight | 8-15 lbs | 2-5 lbs |
| Cycle Life | 300-500 | 2000+ |
| CCA per Ah | 10-15 | 60-80 |
But why choose lithium? Riders prioritizing weight savings for off-road bikes benefit most. However, lithium packs require temperature-protected BMS—sub-zero charging damages cells without heating pads.

FAQs
Yes—select YTX20HL-BS or LiFePO4 models like Pirate Battery YTX20HL-BS (19Ah) designed for Harley Softails. Verify terminal type (T3 nuts) and dimensions against OEM specs.
Can I use Costco AGM batteries in cold climates?
AGM performs better than flooded in cold, but lithium dominates below -20°C. Mighty Max GEL batteries (YTX14L-BS) sustain -30°C storage without capacity loss.
