Costs a Little More But Worth It Long lasting

About 8 years ago, I bought a carbon monoxide detector that came with these batteries. This week, I walked past it and heard a chirp. I bought these exact same batteries for replacement. They are guaranteed to last 2 years. The old batteries lasted EIGHT. They cost a little more than other alkaline batteries, but they are worth it.

Haven't used them yet but reviews are good. Like the fact they are good for 2 years as one smoke alarm is on 10 foot ceiling and I have to get someone to install it for me

Two Year Battery at a Good Price

A two -year battery is great for our smoke detectors, less climbing up the ladder and handling of the detectors.
