I have been purchasing batteries at Sams club for 15 years +, and have never had an issue. I purchased 3 packs of the 48 AA, and 1 pack of the AAA - all of these were terrible. Multiple trail cameras failed only after days in the field - and for context, they should last 2 months. Even my iMac mouse would only last a few days. There is an issue with the batch of Batteries I purchased, or maybe a wider issue. I purchased Duracell's from another store, and No Issues. Honestly, I should probably get a refund - over $100 in batteries wasted.

I bought these batteries thinking they would be good quality and thinking I would save some money compared to the brand name what a mistake instead of saving money I wasted it these batteries are complete JUNK don’t last and don’t even have enough power to make something’s even work

I bought two packs of these a year ago, and all of them have leaked and corroded in whatever I put them in, and even in the package, sitting in the cupboard. Customer service online gave me a refund of what I paid, but didn't offer to do anything about the devices that were damaged by the leaking batteries. Don't believe the "12 year shelf life" claim! Sam's Club used to sell Duracell batteries, and they were far better.

1st strike was the thermostat that the display was blank. I change yearly. Took apart and battery leaked and corroded the contacts in the thermostat. 2nd strike was my GPS, my intuition said check it. Battery leaked and corroded the metal cover and battery contacts. Learned my lesson and should have listened to my brother who had the similar issues. Spend the extra $$ for quality batteries or you’ll spend $$ replacing devices due to batteries leaking!

I bought these, hoping they would perform as well as Energizer and Duracell. I am sad to report they did not. They don't have the 'power' other batteries do. They would not operate our deer feeder- I takes 4 AA batteries. My husband spent hours trying to figure out what was wrong with it, and finally, he took out the brand new Member's mark batteries and replaced them with Energizer, and it worked! MM batteries weren't strong enough for my battery operated LED lights (small string) that I had on a wreath- the lights wouldn't even cut on! I was very disappointed and will not purchase them again, and would not recommend them either.

I have been using member's mark AA and AAA batteries for over 10 years and would have sworn by them. HOWEVER, the most recent pack I bought were duds! I bought the pack of 48 in Sept. and it was gone in a month. I had to replace my soap dispenser, track pad and keyboard batteries almost weekly till the pack was gone! May have been a fluke but I am too scared to try them again. I could have returned to Sams Club, they have a wonderful return policy, but was 1/2 way through the pack when I realized what was going on.

I've purchased these multiple times and now have gone through three packs of 48 on 3 Nest Battery Operated smoke alarms in 1 month each! At first, I thought maybe it was because of the motion sensor, so I turned that off for a month. Then I thought maybe just a bad batch at our location, tried another batch when I was a town over; same results. It seems as if they have gone down in quality over the past few years. I'll spend the extra $5-6 for Energizer batteries next time. Having to change out 6 batteries times 3 a month isn't cheap!

Recently they have not been as good as they use to be I bought some back in Nov 2022 and then had to buy more in Jan 2023 a few months later they were in the box still unused went to use they they are dead they use to last long when in box now they are not reliable I've been getting these batteries for years they use to be great

My tv remote gave me a low battery warning yesterday and when I went to change the batteries, one had leaked significantly into the remote. I cleaned the remote and it still works (for now). The Members Mark AA battery that leaked yesterday has a use-by date of 12-2030 (7 years left). I also had a Canon camera that had Members Mark AA batteries in it that leaked. The camera is dead. Unlike the camera, I use the tv remote every day, but was still surprised at the amount of leakage. I’ve already switched away from using the Members Mark batteries, but was still using the ones I have. Do not recommend Members Mark AA (or AAA) batteries. Thought I would save a little, but made a mistake.

I have been buying these batteries for years and the last two packages I got did not last at all. The first pkg I thought was just a bad batch, but now the second pkg is the same. Quality has really dropped off. Will not buy another of this brand. I'm very disappointed.
