Energizer Lithium Batteries, 9V, 2/Pack

[This review was collected as part of a promotion.] Reliable 9V batteries are required for my smoke alarms and I needed one that is going to last and not die when most needed. Energizer is my favorite brand of battery and I try to stock up on them whenever possible. This is no exception. Great battery.

[This review was collected as part of a promotion.] This is a great battery! We put it in our smoke detector and it works great! I actually feel like our smoke detector is louder - the sound has some uumph to it! The Energizer brand, in general, is dependable so it makes me feel safe and I know it will last a long time.

[This review was collected as part of a promotion.] We seem to have an issue with 9 volt batteries in our smoke detectors. They seem to run out very fast. We decided to try this battery instead. It has not died yet and seems to outlast other batteries by 2 to 3 times. It's worth the money!

[This review was collected as part of a promotion.] Energizer batteries are the best of the best. This Ultimate Lithium 9 volt battery will no doubt last a very, very long time. The design is 100% leak proof. It also boasts that it performs in extreme temperatures from -4*F to 140*F AND has a 10 year shelf life.

[This review was collected as part of a promotion.] I have used the Energizer brand for as long as I can remember. My parents used the brand when I was a child as as an adult, I use the brand of products in my life. I trust the brand and would select it over any other. I recently started hearing one of my smoke detectors giving the noise that indicated the battery is going dead. I opened it and it was an Energizee battery. I have been in my new home now for 5 years and this is the first time I have had to replace the battery. Of course I replaced it with another Energizer battery. I know I can count on Energizer for longevity and reliability.
