I use these in my security cameras, my front doorbell and keypad lock. These are long lasting and I have compared these to other brands and I like the durability of this brand the best.

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 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.

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.

Use them for blink cameras most last me 6 months before I need to switch them on highly used cameras.

I needed these lithium batteries and I don't always find them the normal places I shop. I'm glad to know they are at Sam's when I need them.

They do what they are supposed to. In the long run they will be cheaper than alkaline because they last longer and perform better in cold weather

Best pricing for these expensive lithium batteries
