The best idea for the high ceilings so I don't have to worry about them going out for 10 yrs. I'll see how long they actually do last & get back to you!

You don't find these at the grocery store, and seldom at the hardware store. Lithium's work better than Alkaline's at subzero temperatures (occasionally occurring here in MI). Bought it for my garage door opener keypad for that reason.

if you like quality and saving money then these are for you

This device works, simple and effective. Neighbors dogs barked all the time, now not so much. We placed it 20 feet from neighbors yard but range may be longer. Definitely make sure to keep eye on battery life. Colder climate drains batteries faster.

My smoke detector only works with 9.0 volts. A rechargeable battery has less than 9.0 volts. So a lithium battery is the way to go.

Seems to work just like the expensive ones but no bunny and drums......Great for remotes, radios, meters, smoke detectors and CO sensors and they will not corrode or explode in my experience with Lithium batteries even when stored in your vehicles.

Value for the money. Some say battery too big. But I find it the same size as others 9v batteries. I hope it will last longer compare to other battery. I will update if battery didn’t hold up. So far so good.

I purchased these to replace the batteries in my smoke detector and a scale we use in the kitchen. I was attracted by the lithium type and the 10 year shelf-life, even though I was going to install them on arrival. I can’t yet speak to endurance or battery life.

Just kidding. When I was a kid, that was how you tested a 9-volt battery. You touched the poles to the tongue, and if you got shocked, the battery was still good.Not much I can say about these Amazon 9-volt batteries other than they are a good value and--as near I can tell-- just as good as Energizer, Duracell, etc.

So far, these are much better than the Energizer ones. I’ve had countless situations where the Energizer Lithium 9v won’t fit because of its rectangular shape with straight corners whereas the AmazonBasics version has rounded corners just like an alkaline 9v. It is also closer to the same size of an alkaline 9v.Too early to tell on the longevity of these but I have high hopes since these have been able to fit anywhere I would normally use an alkaline 9v.
