The Truth About Costco Kirkland Batteries

When it comes to purchasing batteries, Costco is probably your go-to place to buy one for your car or your electronic devices. Offering a range of options from well-known brands to their own Kirkland Signature line, Costco provides us with reliable and affordable choices. But what makes Kirkland batteries stand out? Are they as good as the leading brands? In this article, we will explore the world of Kirkland batteries, uncovering the manufacturer behind them, and discovering the value they bring to customers.


We all know it too well: when it comes to powering our devices and vehicles, reliable batteries are essential. Many customers turn to Costco for their battery needs, lured by the promise of quality and value. Within Costco's battery lineup, you may probably opt for Kirkland batteries, because the price is very attractive. Let's see whether Kirkland-brand batteries, whether it's car batteries, alkaline batteries, or hearing aid batteries, are a good choice for our various power requirements. Below we will delve into the world of Kirkland batteries, exploring their quality, the manufacturer behind them, and the benefits they bring to customers.

Kirkland Car Batteries

For car owners, a reliable battery is super important to ensure smooth and uninterrupted journeys. Kirkland Signature car batteries, available exclusively at Costco, have become a preferred choice for many drivers, myself included. Kirkland car batteries are known for their reliability and long lifespan, making them an ideal choice for any driver in Canada.



Who Makes Kirkland Car Batteries?

Costoc does not own battery factories, but instead it works with industry-known partners. The manufacturer behind Kirkland car batteries has been a subject of curiosity among consumers. Previously, Kirkland batteries were manufactured by Johnson Controls, a renowned company in the battery industry. However, in 2019, Johnson Controls' battery production division, Power Solutions, was sold to Brookfield Business Partners. Under this new ownership, Power Solutions was renamed Clarios, and the production of Kirkland batteries continued.

Clarios is a leading player in the car battery market, producing over 150 million units annually, accounting for one-third of the industry's output. With such a strong manufacturing background, Kirkland car batteries can be trusted to deliver reliable performance on the road. This is a great one to know!

Kirkland Car Battery Warranty

One of the key advantages of choosing Kirkland car batteries is the warranty that comes with them. Costco stands behind the quality of their batteries by offering a warranty ranging from 49 to 66 months, depending on the specific battery model. This warranty provides customers with peace of mind, knowing that they are covered in case of any battery failure.

In the event of a battery failure within the warranty period, Costco offers up to 50% refund based on the purchase price of the battery. This refund allows customers to purchase a new battery at a discounted price, minimizing the financial burden of replacing a faulty battery. Even beyond the warranty period, Kirkland car batteries have proven to be reliable, with many customers reporting their batteries lasting well beyond the warranty period.

Costco's Alkaline Batteries

Costco also offers a range of alkaline batteries to meet everyday power needs. Kirkland alkaline batteries, available in various sizes such as AA, AAA, C, D, and 9V, are a popular choice among consumers. What sets Kirkland batteries apart is their value for money!

In a 2016 interview with Atlanta station WSB-TV, Costco's CEO revealed that Kirkland batteries are actually produced by Duracell, a well-known name in the battery industry. This means that customers can opt for the Kirkland brand, which likely has identical quality to Duracell batteries, but at a lower price.

While there is a possibility that Duracell is producing batteries of lower quality under the Kirkland label, many customers have reported little difference in the performance and lifespan between Kirkland and Duracell batteries. Considering the cost savings, even if Kirkland batteries were only 80% as good as Duracell, customers would still benefit from choosing the Kirkland brand.

Kirkland Batteries vs. Duracell: Are They the Same?

To understand the relationship between Kirkland and Duracell batteries, it is important to explore the manufacturer behind Duracell. East Penn Manufacturing Co. Inc., is a reputable company with vast experience in producing lead-acid batteries. It has an exclusive agreement with Duracell to manufacture batteries under the Duracell brand. This partnership ensures that Duracell batteries maintain their reputation for quality and performance.

Considering Kirkland batteries are made by Duracell, the same manufacturer is behind their production too. While there is always a possibility of variations in quality, we found Kirkland batteries to be on par with leading brands like Duracell and Energizer. This makes Kirkland batteries a smart choice for everyday power needs - so you can save while getting a good quality and value for your money.

Kirkland Hearing Aid Batteries

Costco also offers Kirkland hearing aid batteries, which have gained a reputation for their affordability and long lifespan. Customers have reported that Kirkland hearing aid batteries last 2-3 times longer than major brands like Rayovac and Power One. This extended lifespan, combined with Costco's competitive pricing, makes Kirkland hearing aid batteries another excellent choice for those with hearing aids.

Priced at under $0.50 per battery, Kirkland hearing aid batteries provide great value compared to leading name brands, which can cost close to $0.75 per battery. Costco's batteries offer reliable power for hearing aids, thus ensuring that users can enjoy clear and uninterrupted sound at a lower price.

Final Thoughts

When it comes to batteries, we hope that the message is clear that Kirkland is a brand that delivers on both quality and value. Whether it's Kirkland car batteries, alkaline batteries, or hearing aid batteries, Costco provides customers with reliable options. Kirkland car batteries, manufactured by Clarios, offer reliability on the road with a generous warranty that provides peace of mind. Costco's alkaline batteries, made by Duracell, offer customers a cost-effective alternative to leading brands without compromising on quality. Furthermore, Kirkland hearing aid batteries provide long-lasting power at an affordable price.

We believe that this is enough proof to consider Kirkland batteries when you need to buy new batteries next time.
