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

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.

These batteries are exactly what you need when it comes to CR123 batteries. I use them for my Eotech XPS3 and they work wonderfully. They fit the chamber correctly, a problem I have had with other brands, and they last a long time. This is the quality I expect when I buy batteries. The brightness is as expected with no flickering.

Great batteries…reasonable price…..just what I was looking for. Thanks!😊

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???

Good battery’s and a better pice than the local store..

I purchase these lithium batteries when I need long-term performance without having to pay constant attention to whether or not the battery still has power. I find them perfect for the alarm clock backup feature in the event of a power failure and for emergency equipment like radios and flashlights that are not used every day. Their best features are their long life and dependability. These batteries outperform your typical battery by a mile. "Oh, but the cost is prohibitive," some people will say. I can attest that they are worth every penny. One would replace standard batteries at least twice before having to repurchase one of these powerhouses once.

Great battery, a little pricey upfront, but not having to purchase additional batteries for several years these will save you money in the long run.
