Energizer Ultimate Lithium 9V Batteries (1 Pack), Lithium 9 Volt Batteries

These batteries are my "go to" for smoke detectors. They last longer than alkaline batteries (probably double the life). And less annoying beeping from the detectors.

I have a number coded front door lock which takes a battery. I love that this battery will last for much longer than a regular 9 V battery it says 10 years I’d be happy with half that even.

The batteries work as described and did the jobs needed efficiently.

Fast delivery. Good price

Long lasting quality batteries. Easy to use and remove. Price of Lithium batteries needs to come down and recycling needs to improve. May offer ax recycling deposit for return of used lithiums applicable to new purchase???

I replaced the batteries in my wired smoke detectors on September 15th, 2021. I got 4 years out of these batteries. That is twice the life of the best Alkaline batteries I have used in the past.

I use them for my pistol light, typical small size battery, works great, light weight, provides a the full lighting capability of my light for full brightness, battery life honestly unknown because I am not heavily using my light.

Needed some batteries for alarm motion detection. They work as they should and was a decent price.
