Kirkland Batteries LEAK...in fact, eventually they ALL LEAK! AA are worse offenders.
I have been purchasing and using them since 2002. Why not use another brand? Duracells (also sold there) are more expensive and NO BETTER! All batteries constructed in China LEAK, period.
Today, it is all about making things as cheap as possible to maximize profits and more money for the CEO, then wrap it in glamorous packaging with slick marketing. We are living in a sea of *** products, and corporations are under no obligation or government control to do anything different. How long do batteries last now with LED's? Less than they did before with incandescent bulbs, because the issue isn't the wattage used anymore, it's that the batteries won't last as long as a higher quality battery made in the 1960-70-80's.
Their quality was a response by the battery industry to sell just as much - or more - volume batteries as before the LED revolution, by lowering their standards to keep you buying just as many. Do you really think they would lose millions knowing you won't be buying as many? They are made to leak after just few weeks to few months when they should last years using LED's.
There is your answer. And they don't care, and they aren't going to change because of some consumer advocate's complaint.
Reason of review: Bad quality.
Monetary Loss: $13.
