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.

They work exactly like any other standard 9V battery and get the job done without issues. I’ve used them in smoke detectors and other electronics with no problems at all. Performance is what you’d expect, just at a lower price. There’s nothing fancy here, but that’s the point. If you want reliable batteries without overpaying for a brand name, these are a solid choice.

The Amazon Basics 8-Pack 9V alkaline batteries provide dependable power for household devices like smoke detectors, toys, and portable electronics. They arrive well packaged and offer good value for the quantity, making them a practical choice for stocking up. Performance is consistent and reliable, though they may not match the longevity of premium brands. Overall, they deliver solid everyday performance at a fair price and are a smart option for keeping essentials powered.

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!

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.

Work as long and as well as name brand batteries but less expensive. Really a no-brainer.

Amazon batteries always work well, great value

Value for money, very good substitute for Duracell
