I buy it because the tittle says 12 years of shelf life, obviously in Puerto Rico everybody buy batteries and storage because the huracane season, I hope was a good choice.

I am so happy SAM’S offers batteries with the same life span as the name brand ones. And the price is of course so much better on same size same quantity. Why pay more?

My grand-kids would be the ones to rate the performance of these AA Batteries. However, I like being able to get them from Sam's for the money savings. I also like to shop Sam's online which saves me time and money.

Very good batteries at a Great value.. Member’s Mark Batteries are Equal in Quality to any of the other name Brands and they are always more affordable. Thank you Sam’s!

Long lasting, powerful, and affordable batteries. Bought them just in time for the holidays to cover all those gifts that require batteries. Very pleased with this product.

These batteries go dead too quickly. Noticed with fairy lights at Christmas. The one's I had from WM lasted a little over a month in holiday light up decorations. These batteries died in two weeks.

Lasts as long as other, more expensive, name brands. We go through a lot of batteries for my husband's insulin pump. These last just a long as the Duracell batteries.

Looking to replenish the supply at home and ran across these at the club. Have not tried them yet, but the last batch of "copper tops" were made in China.

I live in Florida. I have been using these batteries for years now. I depend on these batteries during periods of bad weather, hurricanes, and power outages. They have never failed me.

These are the most reasonably priced batteries I can find. They have a lot of power when first installed. I'm hoping they have average power life. If not, I'll change this review.
