Kirkland Batteries vs Duracell Batteries

Before we dive in, Duracell is the brand behind Kirkland Signature batteries. While Kirkland Signature is Costco’s exclusive brand, they do count on big-name companies to create these products. 

This does not mean that the two are similar. Let’s check out the main differences between Kirkland Signature batteries and Duracell batteries. 

Price

Kirkland takes the trophy when it comes to affordability. Of course, name-brands will always cost a bit more, but Kirkland Signature offers the same high-quality product at an affordable rate. 

For instance, a 40-count of Duracell AAA batteries is $18.99, while a 48-count of Kirkland Signature AAA batteries is only $15.99.

Size Range

Unlike price, Duracell is the winner when it comes to the size range of batteries. Kirkland Signature only has two sizes, AA and AAA, while Duracell has five sizes: AA, AAA, C, D, and 9V. While they are all 1.5V alkaline batteries, Duracell has a variety. 

Longevity

Longevity is a crucial factor when choosing batteries, and when it comes to Kirkland batteries vs Duracell, Duracell is the winner. 

We found a graph on Reddit that compares the longevity of 11 different battery brands, so you don’t have to. Duracell led the charge as the longest-lasting battery compared to them all, with Kirkland Signature coming in second, averaging 15% less than the name brand.

The amount of power a battery offers is another big factor, and once again Duracell wins. 

Duracell batteries deliver an average of 1.28 volts while Kirkland only gives an average of 1.25 volts. This might not seem like a huge difference but it’s still enough to notice for some devices. 

Warranty

Most power equipment comes with a warranty, and these two brands feature standard examples. For Duracell batteries, you receive a two to five-year warranty depending on the type and quantity of battery you purchased. 

Kirkland Signature batteries come with a 36-month warranty, and you must present the purchase receipt to access the warranty. Both warranties do not cover damage caused by carelessness or accidents, only manufacturers’ defects. 

Environmental Impact

What about the batteries’ eco-footprint? This could be another huge reason why you would want to shop for one brand versus the other. 

While Kirkland Signature does not have an environmental policy, they do make an effort to create environmentally friendly products with recycled packaging and mercury-free batteries that last up to 12 years.

Duracell, on the other hand, has made several movements to reduce its environmental impact with its closed-loop program, which has the company recycling its batteries. They’re also partnered with Call2Recycle to help consumers recycle their batteries more easily. 

Customer Reviews

When it comes to reviews between Kirkland batteries vs Duracell, consumers tend to be happier with the name brand. Not only do Duracell batteries have more power, but they also last longer than Kirkland Signature batteries. 

And this doesn’t mean Kirkland Signature batteries should be ignored as they receive praise from Costco customers. Many shoppers opt for Kirkland Signature batteries at Costco due to the cheaper cost. Plus, they are still high-quality batteries. 

Ultimately, it’s up to the customer to choose what matters most. In this product comparison, the dividing factors are longevity and power vs cost. Either battery brand will get the job done, so you must pick what works for your household and budget.
