Right after I bought these batteries, I put them in a clock and noticed that the clock was running slowly. After testing them in a battery tester, I found that the charge was not 100% but borderline yellow vs green on the chart. These batteries are worthless.

We've used Members Mark (MM) batteries for many years without any problems. They've always performed/lasted better than other generic brands until now. The last two packs we purchased didn't even last half as long as they have in the past. We've always gotten a good 3 weeks out of our LED Christmas lights. This year we had to change the batteries 3 times just to get from Thanksgiving thru Christmas, and they they showed noticable dimming after only the first day or two. I tested several with a battery tester, which showed them to be full. So, I'm at a loss as to what's changed, but we will likely not trust Sam's Club MM batteries again, at least for a long, long time. Even the very cheapest dollar store batteries last longer than these do now.

I purchased these batteries for use in my trail cameras this fall. I've had multiple batteries bulge and almost burst inside the camera. I'm not sure if it's the temperature changes or power usage of the camera, but it's happened in multiple cameras that never had issues with other battery brands.

save your money. more than half of the batteries in the pack were either dead or lasted lest than an hour on first use.

Dont buy put them in solar lights outside and all the batteries after while leak. And they dont last as long as energizer.

We use these batteries in our smoke detectors, temperature sensors, etc. Lasting for up to 6 months has not been an issue. Priced right.

Excellent batteries. I am disappointed, however, in your new policy to charge shipping costs to plus members for purchases of less than $50.

These batteries we used with a timer of 6 hours on and 18 hours off and they only lasted about 2 weeks or so.

There was no issue with the batteries, they work as they should. My issue was with the shipping and package damage.

Made in USA with a 12-2036 date code. Package says 12 year shelf life. I find they last as long as name brands with the benefit of being made in USA.
