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.

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.

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.

Corroded in my label maker. Did not last one year. I am not happy with the quality of these off-brand batteries.

not happy with these... have bought a lot of them through the years and these last two packages are killing my battery operated lights and devices... they are leaking all over the place...

Half of the batteries deformed / busted. The other half have been fine. Prior batches besides the last few have been fine.

I'm not sure if I just got a bad batch but over half of these batteries in this pack don't work and I've never used them before. I won't be buying this again.

We have purchased these batteries for years. We always use them in our Christmas window candles and they last most of the season. This year's purchase has only lasted 2.5 weeks! Something has changed in the quality.

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

They are not very durable. We tried them on different things and there a a good quick solution but not very durable.
