BONAI Lithium Batteries AA 8 Pack - 1.5V High Capacity, Ultra Long-Lasting Performance for Extreme Temperatures (-40°F to 140°F), 10-Year Shelf Life, Double A Batteries Non-Rechargeable

Edited Review: Original review was 2/5 stars based on the comments below. The company reached out and offered a small pack of rechargeable li-ion batteries they produce. Not asked for, but appreciated as those will meet the need we were originally looking to fulfill. The batteries reviewed here do function well for outdoor year-round use and are going on six months with some -10F temperatures.Batteries were powerful and consistently so, but didn't last long at all in some of the Lego motors we placed them in. Purchased these while looking for lithium ion rechargeable batteries. I did find them useful for some outdoor sensors we have since they work well in the cold.These are NOT rechargeable and require special considerations for responsible disposal which cost us $1/battery. Would not purchase again and would instead look for rechargeable batteries.

Had a problem with short battery life while using these in a Blink security system.Was really impressed with the company's customer service when they offered to replace the defective batteries.Would recommend.

UPDATE - The seller contacted me right away and offered to make things right. She offered either a full refund or a new 16 pack of batteries (original order was 8). I'm happy to say that the new batteries work great! Must have gotten a bad batch the first time around. Good product and good price with some great customer service.ORIGINAL - Save yourself some time and effort and buy the Energizer or Duracell. I installed these in our ring doorbell and got less than 24 hrs out of them! Awful. If I wasn't leaving town today, I would be returning these. Don't waste your money.

I use these for a Moultrie Edge 2 cellular trail camera. These batteries last a month compared to the major brand AA (alkaline) batteries. Not only do the batteries last they recover well after cold nights. (Which is tough for any AA battery in freezing temperatures.)In case you are wondering.. No, I haven’t tried any major brand lithium batteries. These worked awesome, so I stopped looking.Moultrie camera has a setting for lithium batteries and it holds16 batteries. Not sure if this helps them last longer or not.**Batteries in picture are 3 weeks old**

The postal package was intact, but once open, the battery package was open. Seemed like a returned product. For long lasting batteries, without knowing if any was used for a while, I feel very uncertain, and it defeat the purchase of buying them. Yet since I urgently need a replacement for a home security device before a trip, I cannot afford the wait to return and re-order. I submitted a review then, but found out the review was not posted. Why? I am now posting again, with an update: the home security device which I put in these batteries ran out of battery within two weeks.........

The best power for me and cheaper also

Using in my Blink cameras so far they seem to be good.
