Long lasting

I always only use energizer batteries because they are the most dependable and last the longest. Especially 9 volt batteries which I use in my smoke detectors which are very helpful for the safety of my family. I change them every year for safety and they have never worn out early or corroded.

10 year lithium battery
on September 22, 2026
Posted by: RikiA
I used this Lithium 9 volt battery in several items including my smoke alarms. A 10 year battery life is great for smoke alarms. A little pricey but it doesn’t need replacing as often so I felt I wanted to give it a try.
