It’s probably my own battery hygiene, but I’ve had so many Kirkland batteries leak over the years that I no longer trust them. I still buy batteries at Costco, but haven’t had the same issue with the name brand leaking.
I've actually had a whole pile of Duracell CR2023 batteries from Costco leak inside the packaging. (You can google for various reports/pictures of the problem.)
Wild. I wonder what could cause that?
I don't use a lot of AA/AAA batteries, so I'll buy a pack from Costco and it'll sit in my drawer for 5+ years without issue. They go into a TV remote or bathroom scale or whatever and last a couple years with no issue.
