This was my second purchase of these batteries. The first was in January, 2025, almost a year ago. Nothing I have put the first batch into has run out of battery yet which is impressive. Right away two batteries went into a cordless keyboard that I use daily and to date the status bar still says 100%. It's possible that the sensor doesn't read lithium ion batteries accurately, I suppose, but Duracell alkaline batteries never lasted this long so I'm impressed. And particularly happy that I don't have to worry about the batteries ever leaking. One thing I have noticed is that the batteries seem to be slightly larger diameter than alkalines but that has not caused any problem installing them. Read more
These AA batteries are dependable and provide steady power for all kinds of devices — from remotes and toys to flashlights and smart home gadgets.

Highly recommended for anyone looking for quality, long-lasting AA batteries that deliver reliable performance every time! Read more
I bought these for my doorbell and security cameras, and they’ve been excellent. The 3000mAh power lasts noticeably longer than standard AA batteries. No issues with performance, and the price is great for how many you get. Really dependable. Read more
SERVE THEIR PURPOSE, BATTERY LIFE NOT SO LONG. IT COULD BE BECAUSE I HAVE PEOPLE WALKING BY ALL DAY AND NIGHT Read more
These Enegitech AA Lithium Batteries are fantastic! They last much longer than regular alkaline batteries, making them perfect for my Blink camera and doorbell.

Overall, they are excellent value for money and highly recommended for anyone needing long-lasting AA batteries. Read more
Bought these to try in my chicken coop camera which is obviously outside in the cold, half of the batteries died within hours. Put 2 in today around 10 and by the time I checked the camera at 2 it was dead. Brought them in and did a battery check and they were dead. Read more
I am impressed with the longevity these batteries provide. My BLINK camera system has one cam too far from the house to run direct power - so I use the battery system which asks for Lithium. A normal Duracell battery lasts maybe one or two months. These lithium batteries are running 4 to 5 months and beyond. Glad I found them. Read more
I use lithium-ion batteries almost exclusively in field instruments. They have advantages of long life compared the alkaline batteries, don't leak like alkaline batteries (which has ruined a number of expensive instruments), and sometimes have greater power supplied vs cost, but not these . I usually use Energizer lithium batteries which have the same rated capacity as this product, 3000 milliamp-hour at a rated constant load of 200 ma. Thought I'd give these a try. I had my doubts. A phrase that has served me well, "trust, but verify". As I did with the Energizer batteries when I switched to them from alkaline, I load tested one with an instrument that provided a constant load (in this case 200 ma, the load given in this products specification). The test was set up to end once the voltage reached "dead" at 1.25 volts, again, the voltage listed in the specifications as read off the graph. The total was 2466.4 mAh. Only 82% of the products rating. The Energizer, also rated at 3000 mAh, performed better than it's rating providing 3060 mAh. I even gave this product a chance to do better by restarting the test two more times to get all I could out of it, which amounted to all of 52 mAh more. So, the question remains, do you get more energy for your money with these? Maybe, or maybe not. Depends on the current price point. Regular high quality alakaline batteries are rated at 1150 mAh, so you would need to buy roughly 9 alkaline batteries to equal 4 of these lithium batteries. Or at current prices, these cost $1.87 each, alkaline about $.81, so cost per 1000mAh is ... Lithium $.758, Alkaline $.704. Alkaline wins. But.. if these batteries performed as advertised, you would be getting a deal at $.623 per 1000 mAh. You aren't. Bottom line for me is that the product does not meet advertised specifications. Hope this helps your decision making. Read more
