Amazon Basics 8-Pack 9V Alkaline Batteries, 5-Year Shelf Life - for Smoke/CO Detector, Electronics & Audio

Let’s not pretend these are magical batteries forged by lightning in the hands of Zeus. They’re Amazon Basics 9Vs. They’re basic. Like, pumpkin spice latte in a flannel kind of basic. But you know what? They work. And they don’t cost $47 a pack like some name-brand nonsense that comes in packaging you need power tools to open.I bought the 8-pack thinking, “I’ll never use all these.” One week later, I’m replacing every smoke alarm battery in the house and two kids' toys that haven’t worked since 2019. These little boxes of electricity just keep disappearing like I’m playing whack-a-mole with battery powered devices.They just… work. Like a solid C+ student who graduates and gets a dependable job. Not a rockstar, but someone you can count on to keep the house from burning down. And that, my friend, is all I really wanted. So 5 stars for living up to my expectations.

I've been buying these Amazon Basics 9V batteries for years now to use in our smoke detectors and have yet to have a battery not last at least 6 months. Great value!I may be biased because our house has 8 smoke detectors... seems to work out well for everyone involved.

Good quality 9V are getting very hard to find. Even cheapies are hard to find. These are good to put in a product that needs some serious power.

They’re batteries. Purchased for my smoke detectors, and I bought this brand for the environmental reference as well as the advertised shelf life since I won’t use all of them at once.

put these in my smoke detectors and they lasted 2 years instead of other cheap batteries that only last one year. would recommend

Perfect batteries a reliable. Strong. And lol beautiful I color.. I will buy again for all my guitars and radios and other electro domestic. Gadgets I have………. Price is almost a giveaway ,,! That said. They the 9 volt. Smal triangular. Battery locally cost just one 4$ up to 5.80 each .. so it a steal buying them here….

I use these for replacement in our smoke alarms and replace all of them at the same time. They have been great and used for maintenance personnel to connect. I would recommend purchasing.
