Excellent. We have been using these for years and they are just as good and even better than some brand name batteries. We always have them on hand in the event we need batteries..

I have come to trust the Members Mark label for almost anything. I just removed 15 copper-tops from a piece of test equipment that I had forgotten about for a year or so. All 15 copper-tops were leaking and I had to replace the battery holder as well as the cells. Yes, I should have removed the cells, but it is a piece of equipment that I use fairly regularly. I hope I can trust these MM cells to last longer and not leak.

Members Mark batteries are very reliable and last long. The amount of batteries you get for the price is great

We have so many things that operate off of batteries that I buy these all the time at Sam's because they are as good or better than Energizer or Duracell batteries and don't cost as much.

These batteries work great. They are a wonderful price to have on hand for the up coming holiday season

Great price for large quantity. Only negative which to us price difference equals it out... is they do not last as long as more expensive certain name brands but the difference is nothing major and price makes up for it in our opinion

Batteries don't last long

I have bought these in the past and they have been fine, but this pack of batteries had many that were dead right out of the pack and more that were going bad but still had some power. Very disappointed

These are the worst alkaline batteries. They have leaked and damaged almost every device I have used them in. They leak well before the device shows signs of low battery. As others have said, they even leak new in the package. The famous I'm pretty much done with all alkaline batteries. Rechargeable or lithium for me.

I had regularly purchased Member’s Mark batteries without much thought. Earlier this year, I bought both AA and AAA packs. After using them in multiple devices, I noticed they drained much faster than expected. To be fair, I tested them in my doorbell, which uses four AA batteries. A fresh set normally lasts around six months, but with this pack it reported low battery in under two weeks. I saw similar short life in other devices as well. I returned the remaining packs and customer service was courteous, which I appreciate. But the inconsistency was frustrating, especially for something like a doorbell where dependable power matters. Based on this experience, even as a former repeat buyer, I’m not comfortable purchasing these again.
