Have you ever wondered who makes Kirkland batteries? You would be surprised to know about the manufacturer, especially if you compare the batteries with Duracell batteries. Though being branded under Costco's private label, it is made by some other brand. In fact, all the Kirkland Signature products are made by third-party manufacturers. Kirkland Signature is an in-house brand of Costco that sells different types of products under the label. The products range from Kirkland brand toilet paper to batteries to coffee, which is why shoppers often want to know who makes costco toilet paper and other Kirkland Signature products. The manufacturers make some products exclusively for Costco, while some are made by brand labels who sell their own branded versions of the same product. The only difference in such products sold by Kirkland is that they have much lower prices and a Kirkland Signature red and white label. This type of private-label research is similar to how consumers evaluate other products before purchasing, such as reading zoro tools reviews to understand product quality and reliability. Similarly, shoppers may compare detailed product information before buying appliances, such as a haier fridge double door review, to understand features, performance, and customer experiences. The same approach applies to major purchases, where consumers may compare brands through resources such as ge vs whirlpool refrigerators before deciding which option offers better value.
Who Makes Kirkland Batteries?
Kirkland batteries are manufactured by Duracell. In other words, Kirkland Signature batteries are made by Duracell. Costco's CEO, Craig Jelinek, revealed this in an interview with WSBTV News in 2016. They manufacture both AA and AAA batteries for Costco Kirkland Signature, which is Costco's Kirkland battery line.
Does Costco Also Sell Duracell Batteries?
Yes, Costco sells both Kirkland and Duracell batteries. Duracell offers a wider variety of sizes - AA, AAA, C, D, and 9V - while Kirkland is limited to AA and AAA sizes. Like many retailers, Costco pairs national brands with its own house brands. Some shoppers also compare Amazon Basics batteries as another budget-friendly store-brand option, and may check pricing at mass retailers such as Walmart.
Kirkland Batteries Vs Duracell Batteries
Price
The cost of a 48-count package of Kirkland Signature AA Alkaline Batteries is $13.99, i.e. $0.29 per battery. Buyers spend less on Kirkland for the same battery size, while Duracell's AA batteries are priced at $0.40 per battery, about 40% more than the price of the same battery under Kirkland's name. The savings can be a bit more noticeable when batteries are purchased in bulk or on sale. Store coupons can also affect the final price comparison.
Size
Duracell has more variety to offer when it comes to size. Kirkland Signature only has two sizes, AA and AAA. But Duracell has five sizes: AA, AAA, C, D, and 9V. AA and AAA are the sizes most people keep around for everyday devices like a tv remote, toys, and game controllers. They are also common picks for flashlights. Though, they are all 1.5V alkaline batteries.
Durability
Duracell's batteries are more long-lasting than Kirkland Signature, with Kirkland averaging 15% less than the Duracell batteries, so Duracell comes out ahead on durability and longevity. In a practical comparison of two brands, head-to-head tests and research often focus on how long batteries last in everyday use.
Power Output
Another important factor is the amount of power a battery offers. Duracell batteries give an average of 1.28 volts, while Kirkland batteries give an average of 1.62 volts. Battery chemistry can affect output and consistency, and the materials used in alkaline batteries also play a role in overall performance.
Warranty
Duracell batteries come with a warranty of 2-5 years, depending on the type and quantity, and longer coverage can reassure consumers when reliability is not fully guaranteed. Kirkland batteries come with a 36-month warranty. Both of them cover only manufacturer defects and not damage caused by accidents. Also, both claim a 12-year shelf life. How they are stored can affect how long they last and whether they leak over time, since leakage risk can increase as batteries age.
Other Brands That Manufacture Kirkland Signature Products
