Annoying fire alarm batteries needed replaced. Better price on amazon than in stores. Work good. Lol not waking up in a panic at night.

I love the Amazon Basics 9V Alkaline Batteries. I use them for smoke and CO detectors as well as other electronics, and they last longer than many other brands I’ve tried. The performance is consistent, and the 5-year shelf life is a big plus for keeping extras on hand. Great quality at a great price. Amazon Basics batteries have become my go-to choice. Highly recommended!

Dateline: A Darkened Room, a Chirping Smoke Detector, Late Saturday Night. It is a sound from the seventh circle of hell. The sharp, insistent, high-pitched CHIRP of a dying smoke detector battery. It is the universe's way of telling you, at three in the morning, that you have failed to prepare. It is a moment that calls for a specific and increasingly rare tool: the humble, blocky, 9-volt battery. This strange, rectangular power source is a relic from another time, yet it persists, the stubborn, beating heart of our most critical and our most bizarre devices. It powers the smoke alarm that saves your life, and it powers the vintage fuzz pedal that makes your guitar sound like a dying woolly mammoth. You need to have them on hand. You need a stockpile. Enter the Amazon Basics 9V. This is not the high-priced, celebrity-endorsed battery you see advertised during the Super Bowl. This is the people's battery. The pragmatist's choice. A simple, no-nonsense power brick that delivers on the one thing that truly matters: incredible, undeniable value. Let's be honest. In a head-to-head, long-distance race, will it outlast its big-name competitors? Probably not. It might run out of steam a little sooner in a high-drain device. But that is missing the point entirely. The point is that for the price of two or three of the "premium" batteries, you can have a whole damn arsenal of these things sitting in your drawer. You are not buying a single marathon runner; you are buying a fresh team of sprinters, ready to be tagged in at a moment's notice. And they will be ready. This is the second, and most crucial, part of the bargain. These batteries don't die in the drawer. They don't leak a foul, corrosive bile all over your other junk. They hold their charge with a grim, respectable tenacity. They sit there, for years if need be, patiently waiting for the call to action. Whether it's for the life-saving chirp of the smoke detector or the soul-stirring crunch of a guitar pedal, they are ready to serve. For the sheer, overwhelming value proposition, these cannot be beat. They are reliable, they are affordable, and they allow you to maintain a healthy supply of a crucial power source without taking out a second mortgage. They are the perfect, five-star solution for the well-prepared and the perpetually paranoid. A solid, working-class hero in a world of overpriced superstars.

I purchased the Amazon Basics 8-Pack 9V Batteries, and they’ve been excellent. The quality is solid—each battery delivers consistent power and lasts a long time in my devices. They’re perfect for smoke detectors, toys, and other electronics that need dependable energy. The best part is the value: you get eight batteries at a very reasonable price without sacrificing performance. They’re well-packaged and easy to store, making them a smart choice for keeping backups on hand. If you’re looking for affordable, reliable 9V batteries, this pack is a great buy. Highly recommend!

5 stars because there’s nothing to say, really. The batteries work as well as any other 9 volt. I like to get Amazon’s version because they’re the most cost effective compared to a big box store. They last just as long as any other batteries. We basically only use them to power our code locks on the doors of our houses, but the door lock will last for years, so good deal.

So far so good, they seem to work as well as the brand name ones. I have tried Amazon basics before and have been impressed with the quality, and these will go on my list of repeat purchases.

Good value for the price. We use these for our smoke detectors and each battery lasts a year (or more). Nothing fancy, they're simply cost effective & reliable.
