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.

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
