Energizer 123 Batteries, Lithium CR123A Battery, 6 Battery Count

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.

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.

Needed batteries quickly. Bought at local CVS. Paid three times more than Amazon for same quantity.

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???

The glass break portion of my alarm started to beep and the panel said "low battery". I went to Amazon, search for lithium 9-volt battery. Among the vast number of choices there was one from Eveready. This being a brand name I know and respect, so I purchased it. One day later it was at my front door. I replaced the old battery with this new one. Now everything is quiet and working properly.

Good

Only buy energizer, cheap chinese ones will give lot of trouble.
