Sooo much better than an alkaline battery. This actually clicks activates my solenoids without air since it actually has the amps to do it. Very impressed. As mentioned in other reviews, the edges are rounded so more likely to fit in devices compared to the Energizers variant. Have and will be buying more... maybe quite a few more :)

We haven’t had any problems with them!

I finally got wise and signed up for the subscription service for 9 volt batteries. You can ask for every 6 months so I always get a reminder to change out the smoke detectors. and no fighting shortages when everyone runs to the store because there is a hurricane in the Gulf!

I bought this battery for use in a smoke detector where it was not easy to replace it. Unfortunately, the battery lasted 11 months, much shorter than the ad suggested. Note: "Shelf Life" means sitting in storage unused.

Batteries are made pretty much the same by each manufacturer. In sprite of what a little bunny may have told you, the brand is nowhere near as important as the type. and materials. With the long shelf life, these are especially great in test equipment that sits longer than is actually used. Any nine volt product will do better with these.

These 9v batteries by Amazon Basics seem to be of good quality at a reasonable price. They are slightly smaller than competing Batteries, so the fit better in your devices.

The best thing is that the battery keeps full power for a long time. Regular batteries lose their power little by little, so the performance of the metal detector drops while the battery is still "good." However, that does not happen with this battery. The power will drop off all at once, so I will be able to change batteries and start all over again rather than having just a brief time of full power. I wish it lasted longer--the next time I will keep a log to see exactly how many hours it takes to discharge.

These are perfect for smoke & Co2 alarms. They last at least twice as long as alkaline batteries but they don’t cost twice as much. Why pay more for name brand batteries?

I needed a 9 volt Lithium battery to weather Michigan cold. I had tried standard batteries, but they didn't last the winter. I bought the "Amazon Basics 4-Pack 9 Volt High-Performance Lithium Batteries" which were more reasonably priced than other brands. I use them in a remote motion sensor that sounds an alarm whenever a car enters my long driveway.

Battery works as expected for a pet no-bark item purchased from Amazon. It émis a tone that interrupts barking, so having a long life battery is a must for apartment living. Barking would be a problem where I live, so this battery has already lasted longer than the previous battery! Yay, “No bark.”
