Who are Kirkland batteries made by?
Kirkland batteries are manufactured by Costco Wholesale Corporation under their private label brand. These batteries are typically produced by established battery manufacturers through white-label partnerships. While specific OEM details vary by product line, Kirkland automotive batteries have been historically associated with major lead-acid battery producers like Clarios (formerly Johnson Controls). For lithium-ion products, Costco often collaborates with specialized energy storage companies.

What types of batteries does Kirkland offer?
Kirkland provides lead-acid automotive batteries and lithium-based specialty batteries. Their flagship 12V car batteries feature AGM technology with 650-850 CCA ratings, while lithium products include 24V/36V packs for power equipment. Pro Tip: Check date codes – Kirkland batteries use Julian dating (ex: C2 = March 2024).
Kirkland’s automotive line focuses on flooded and AGM lead-acid chemistry optimized for cold cranking performance. Their deep-cycle marine batteries utilize thicker plates (4-5mm) compared to standard automotive versions. For lithium offerings, they partner with manufacturers using LiFePO4 cells rated for 2,000+ cycles. A typical Kirkland golf cart battery (48V 100Ah) delivers 5.1kWh capacity with IP65 waterproof casing. However, unlike specialized EV batteries, they don’t incorporate active thermal management systems. When considering alternatives, you might explore options like UPS power solutions for different energy needs.
How do Kirkland batteries compare to OEM brands?
Kirkland batteries match OEM specifications at 20-30% lower cost through bulk manufacturing. Their Group 65 automotive battery weighs 41 lbs versus OEM’s 43 lbs, achieving parity in reserve capacity (120 minutes) through advanced plate alloys.

FAQs
No, this is a common misconception. While Duracell makes some Costco products, automotive batteries come from different suppliers. Recent teardowns show Kirkland car batteries use stamped plates identical to Clarios’ DieHard production lines.
Can Kirkland lithium batteries be used in solar systems?
Yes, but with limitations. Their 12V 100Ah LiFePO4 batteries support 2000W inverters, but lack built-in MPPT controllers. Always add external circuit protection when integrating into solar arrays.
