    • Great "Store brand" Batteries
Size: 4-Pack
This are really good batteries! They work very well and I am glad that they are "store brand." I'm sure these will last a long time, and they were a good value for my money! These batteries of course don't leak, and I am looking forward to using them more in the future!

    • Dependable Power with a Solid Shelf Life
Size: 8-Pack
Review Image by Erin
I recently picked up this pack of Amazon Basics 9V alkaline batteries for my home’s smoke detectors and carbon monoxide alarms, and they have performed flawlessly. The build quality feels substantial, fitting securely into my devices without any issues. One of the standout features for me is the 5-year shelf life; it provides great peace of mind knowing I can keep extras in the drawer for emergencies without worrying about them losing their charge. For a high-drain or safety-essential item, these offer the same reliability as the big-name brands but at a much more reasonable price point. They are a practical, no-nonsense choice for anyone looking to keep their household electronics running smoothly. ... show more

    • Must have and cheap!
Size: 8-Pack
These batteries are a great value for the price. They’re consistently cheaper than most name-brand options, but the performance really holds up. I use them in everything from remotes to kids’ toys, and they last just as long as the more expensive brands I’ve tried. I’ve been buying Amazon batteries for a while now, and they’ve proven to be reliable across the board. I haven’t noticed any drop-off in quality compared to name brands, which makes them an easy go-to. If you’re looking to save money without sacrificing performance, these are definitely worth it. ... show more
