Been buying these batteries for years only had one time they didn’t hold up the way they were supposed to and Sam’s gladly refunded my money with only a phone call. It’s a win-win situation. Would recommend to anyone.

Good inexpensive batteries, ideal for those things that do not need lifelong batteries such as the holiday candles you put on your table and things for that nature we’re minimal amount of power is consumed from the batteries and these LED lights works perfect at the end of the season I’ll be able to take the batteries out and use them someplace else, but at least for the duration of the holidays I have had my blinking lights

These Batteries work as well as any other battery that we have used. They will sit for a long time and still perform well. If you forget to remove them from something you don't use often they seem to remain leak free. What more do you want from an inexpensive battery.

Overall great batteries in price and value. I like the fact they are guaranteed for such an extended period of time. I am concerned with the overall ever increasing prices at Sam's Club. Especially over the past six months. It's becoming less expensive to shop at my local name brand grocery store.

Haven't tried them yet but my daughter told me that I needed to order them because she said they're much better than Meijer brand she said she's never bought my or brand ever since she's been buying from Sam's Club remember Mark batteries she said they last much longer so I'm glad I got them and a good price

Quality has gone way down. I used members mark batteries for years. Lately I have had both AA and AAA batteries leak. I’ve also had brand new AA batteries last less than 30 days in a TV remote. This is a new experience and I’m disappointed after many years using your batteries.

So far I’ve tried 4 batteries and none have worked. Others I had here did work, I know the issue was not the devices.

About 1/2 of these batteries fail to generate the power needed to light the devices we’ve used them in. Energizer and Duracell have no issues with the same devices. Batteries do not expire for 2 years, so they’re not old.

Typical performance when it works. Will leak and spill corrosive gunk all over your devices. I am writing this review just after realizing that yet another desk clock in my office has been destroyed by a faulty battery. 5 cent part has destroyed another $12 clock. Previously I have lost more battery operated small equipment (calculators, oximeters, etc.) Lastly, "better" brands are not faring any better.

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.
