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

I’m really happy with the energizer 9v lithium battery. It works great seems to last much longer than standard 9v batteries. I like that it has a long shelf life and will be reliable when I need it.

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.

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.
