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!

Decent price for these Amazon brand 9 volt batteries. They work fine in smoke detectors, etc. and have a long shelf life. They seem to last just as long as the name brand batteries for considerably less money.

These work long enough to forget if the Duracell this battery replaced lasted longer. Plus they are lots cheaper than Duracells. Plus they fit the Power Pack PP3 connector, that pinnacle of 1956 battery engineering!

I used to only buy the "big name" brands for my household batteries, especially for critical things like smoke detectors. However, after trying this Amazon Basics 4-Pack of 9V Alkaline Batteries, I'm officially a convert. They offer the exact same performance without the "brand name" markup. 1. High Performance Right Out of the Box I tested each of these with a multimeter as soon as they arrived, and they all registered at a consistent 9.5V to 9.6V. They aren't sitting on a shelf losing power; they arrive fresh and ready to go. I’ve used them in everything from high-drain RC toys to my digital multimeter and acoustic-electric guitar, and they haven't skipped a beat. 2. The 5-Year Shelf Life is Real The 5-year leak-free shelf life is a huge selling point for me. I like to keep a few extras in the "junk drawer" for when that dreaded low-battery chirp happens at 2:00 AM. Knowing these will still be at full strength two or three years from now gives me total peace of mind. It makes stocking up for emergencies or power outages much more practical. 3. Perfect for Smoke & CO Detectors If you have multiple smoke or carbon monoxide detectors in your house, the cost of replacing batteries every year adds up fast. These fit perfectly in the battery compartments—no struggling with tight fits or weird dimensions. They provide steady, reliable power that lasts just as long as the expensive copper-top alternatives I used to buy. 4. Frustration-Free Packaging I actually appreciate the Certified Frustration-Free Packaging. There’s no sharp plastic clamshell to hack through with scissors. The box is easy to open, and it doubles as a neat little storage container for the remaining batteries so they don't roll around and short out against each other. Pros: Incredible Value: You get four batteries for the price of two from most other brands. Reliable Longevity: Lasts just as long as premium brands in low-to-mid drain devices. Leak-Proof Design: 5-year shelf life ensures they are ready when you need them. Standard Fit: Fits perfectly in smoke detectors, garage door openers, and guitar pedals. Cons: These are single-use alkaline batteries, so they aren't rechargeable. Not intended for extremely high-drain industrial tools (stick to lithium for those). Final Verdict: There is no reason to spend twice as much on "premium" brands for everyday household items. These Amazon Basics 9V batteries are reliable, long-lasting, and arguably the best value on the market. I’ll be buying these exclusively from now on

These batteries have been very reliable so far. They provide strong, consistent power and work perfectly in smoke detectors and other devices that require 9V batteries. Installation was straightforward and they fit securely without any issues. One thing I appreciate is the long shelf life. It’s nice being able to keep extras on hand without worrying about them losing charge while stored. The packaging also makes it easy to organize and store the batteries until they’re needed. Overall, this pack offers excellent value for the price. If you need dependable 9V batteries for household electronics or safety devices, these are a solid choice.
