10 year lithium battery
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.

Powerful
This battery is amazing, I had to change out the battery in the fire alarm and that was 2 years ago and its still going. Im amazed at the longevity of this item.

Standard 9V
What’s there to say - this is a standard solid 9V battery. I’ve got it in my smoke alarms and it’s been going strong for a long time. No complaints it has a lot of charge

They work as intended
The output is fine, the size is the same as others, durability is hard as a rock. If you have ever shot one of these with a 0.22 bullet they explode and makes a fun boom.

Works great
Purchased for my wife’s grandmother to use in her alarm clock. Even though it’s plugged in the battery will help when the power goes out so it’s long endurance will be great.
