I bought this 12-pack about 6 months ago. I used 4 in my stationary bike and set the other 8 aside. The package guarantees a 10-year shelf life. The first four finally went dead after about 6 months. I replaced them with the second four. They were dead also. I replaced the second four with the third four. They were dead also. My take on this? Only buy what you can use immediately because if you wait 6 months, they will be dead. But of course, Sam's doesn't give you the option of buying only four batteries. So buy your batteries somewhere else.

They are good batterys still working

Great for my Mr. Beams lights.

Almost every battery leaked inside the flashlights. Extremely disappointed

Great Batteries. They work just as good as the name brand, for a little less money

These batteries do not last

Great price for alkaline batteries

In a few months they have to be replaced. Batteries should not wear out that fast.

Stick with the name brand, so far out of 8 batteries tried, 4 are dead from a brand new pack

Needed replacements for standalone fan.
