BEVIGOR Lithium AA Batteries 24 Pack, Long Lasting 1.5V 3000mAh AA Battery, 20-Year Shelf Life Lithium Batteries for Blink Camera, Flashlight, Microphone, Alarm System【Non-Rechargeable】

Perfect, as described. Excellent power and charge for devices. Purchased for my outdoor security cameras and have had no issue, long lasting and durable. Not heavy or overly bulky - quick change out for any device.

These batteries have not lasted a week in my blink cameras I thought I might just be one but it's all of them what a waste of time and money...... Update 11/25 the company did give me the fullest apologies and also refunded my full purchase so I would recommend using this vendor again because they did make it right and I like to do business with people who stand up for any problems their products may have and try to fix it in any way possible

This pack of 24 lithium AA batteries are a great value to replace expensive lithium batteries from the major manufacturers. Keep in mind these are non-rechargeable lithium batteries. I purchased them to replace the dying batteries on five Nest Protect smart CO/smoke detectors and some Ultraloq smart locks in my home. The Nest Protects take 6AA each, and I was surprised and disappointed after replacing the batteries in the first Nest device that it would not turn on. Nothing. I tested each battery with a multimeter and they were all at about 1.8V which is better than expected for an AA battery which is normally rated for 1.5V, so these should last extra long but for some reason they didn't work at all. Upon closer inspection I realized that the positive terminal on these batteries is much shorter than on standard AA batteries. The overall length of the battery remains the same - the body is slightly longer to compensate for the shorter terminal, so this feature may have no impact in most electronics. In the Nest Protect devices however, the way the batteries are seated, the positive terminal is just too short to touch. I ended up having to carefully bend the contacts inside the nest protect device outward toward each battery in order to make contact, which I should not have to do. After that modification my Nest Protect did turn on but it's concerning that they aren't manufactured to match the specs of most other AA batteries. Both my Nest and Ultraloq devices are now showing high battery output with about the same level of drain or better than more expensive brand batteries. I will continue to buy this brand as a more affordable alternative lithium battery, with the understanding that the shape is not consistent with regular AA batteries and depending on your device you may have to do some modification to make sure the batteries make good contact.

The batteries work great and last about 3 months with constant use in the blink cameras. They came fast and just as good as the energizer ones. They last a year in the cameras that don’t film 500 videos a day. I have a camera on a humming bird feeder , the battery gets a lot of use.

Turns out I did buy these. I had another review for a similar purchase. The main interest was quantity as the local stores sold 12 packs for nearly the same price.The brand was new to me. Still? I decided to give it a chance to see if it would avoid trips to the store for replacements. They have. No issues for sizing, durability, cost and general powerI am happy with this.

I am pleasantly surprised how well these are working in my yard cameras. The non lithium batteries would be drained half way by now. These are light too. I will buy again.

HARD TO WRITE ANYTHING ABOUT LIFE OF BATTERIES LIFE IS DIFFERENT WITH ALL APPLICATIONS BUT ALL OF THEM HELD UP VERY WELL. IN GENERAL USE IN THE HEAT AND COLD

Give these a try, this was my 2nd purchase. I really wish they were rechargeable but that's ok. I have a couple of cameras that get a lot of hits and that runs the batteries down faster but like I said, they get a lot of hits.Otherwise, these are great batteries and the price is right plus the turn-around time on the sale to receipt is very reasonable. No problems to report with them. I fully recommend them.
