These generally provide a higher Voltage rather than just 1.5 Volts. They also run till the device stops. They generally seem to last a lot longer than a regular AA Battery.

I use these in trail cameras. They maintain full strength taking full length videos till they die. Cold and darkness don't affect them like they do alkaline batteries. The cost three times a much and work three times as long.

I have Blink cameras and they originally came with these batteries. They lasted almost a year without needing replacement in some cameras (some are still going strong). I ended up using some Duracell batteries for the camera and they only last two months. I ended up getting these at Sam's Club and my hope is they will last over a year. These batteries are more pricey than regular lithium batteries but they are well worth it for the length of time they last.

Great price. They buying process needs to be changed as i had too much hassle buying this product since it was locked up on the cage. Employee at the door did not know the process so i was sent running all over the store. Being a senior citizen I didn't need this. I will remember this for the next time I need to purchase.

as described and a good price

Like that they last a long time.

kind of expensive, but best batteries by far i've used. Last 5 times longer than generic ones.

They say that these batteries don't leak, but they do, just not as often as normal batteries. They seem to last a little longer, and I prefer them for certain applications, but they have become so absurdly expensive, I use them much less often than I used to.

I bought these with the hopes of having them last through the holiday season on a set of 50 outside mini LED lights requiring 3 AA batteries each. The promise of “ultimate” performance and a long lasting battery life did not happen. After 2 weeks the lights were dimmed and then a few days later out completely. I bought enough batteries for 15 light sets at more than triple the price of regular energizer AA batteries. My standard energizer batteries lasted longer last year than this year’s ultimate lithium batteries. All have already been replaced. These were not worth the money and I would not recommend them. I will not buy them again.

These batteries work fine as long as you charge them before use. I charged and stored them. When I used them they were about half charged and didn’t work. Strange for Lithium batteries.
