The Real Brands Behind Costco's Kirkland Products

2. Kirkland Signature Batteries: Duracell
There are certain things shoppers don't like buying off-brand because they know they won't last as long as their quality competitors. Batteries happen to be one of those things.

Luckily, Kirkland Signature Batteries won't disappoint you in that way, since they're actually made by Duracell. Costco’s CEO, Craig Jelinek, revealed that tidbit to Channel 2's Consumer Advisor Clark Howard in 2016. Now you can buy a bulk pack and know you're buying quality.
