Best (and only?) AA lithium cell on the market
Obviously, Energizer makes great batteries. Whether you prefer these or the copper tops is personal opinion, but to my knowledge the copper top guys don’t make a lithium AA sized battery. The manufacturer of my particular product actually recommended to use these exact batteries due to longer lifespan and reduced chance of leaks. Batteries came quickly via free overnight delivery and were a fresh batch.

Great battery's and they are more then reliable!
Best batteries ever. These are literally brand new and I could tell that they were just made because they are dated not even for a year ago. They are solid. They fit great and packaged good and the best value for the money well spent. These will get you a long time! There capacity retains the same as any other usually energetic double aa battery and the shipping speed was super fast. I had them the very next day!

Great for when it's difficult to change the batteries
I don't use these in all my devices that take AA batteries ('cause they are kinda expensive) but for some things that are a PITA to change the batteries, these are great. For example, I have an outside temp sensor that is not very accessible; in that device these work great. These will also keep working at temps where an alkaline battery will roll over an die. Love the 25 year shelf life of these batteries.

Great battery
I love these batteries tho I will say they are a little bit more money, but they last so much longer. The use on them is amazing. I mostly use them for my doorbell cameras. I never have no issue with video and they fit perfectly.

Works with nest Smoke/CO monitors
If you're here because you have Nest smoke/CO monitors - yes, these are the correct ones! They work great and are the only kind I have found that will work/hold a charge for the detectors! Besides that - batteries are batteries!

Good cells but beware
Very good long-lasting batteries. BUT, occasionally one will completely die while others in the same device are at full or almost full charge. So, if you don't have a battery tester, you will assume all are bad and toss them. These are too expensive to throw away. So, get a battery tester.

The standard for smart smoke detectors and wireless cameras.
Goodness, these aren't cheap. BUT, it's what you need for Nest smoke detectors and cameras. Blink cameras and doorbells as well. Does great in my smart door locks that don't 'require' them, but perform better with them.

A must buy
They are expensive but a cheaper way to buy batteries in bulk
