NINMAX® Hyper Lithium AA Batteries, 20 Pack 1.5V Longest Lasting Double A Battery, Low-Temperature Resistance Upgraded Version【Non-Rechargeable】

So far so good! - looking forward to longer life with my simply safe door lock (garage). in the winter normal batteries don't last long so looking forward to these batteries.With the higher voltage you can hear it in the lock motor running much faster.

These are good batteries, I've tried them out in my Canon Speedlite flash and have found them to be quite good at powering it. I plan on using them with that Speedlite to see how well they hold up compared to the Energizer Lithium batteries I normally use.I haven't had any issues with these batteries but they cost about a buck cheaper than name brand Energizer Lithium batteries so I'm not sure why I would recommend these over a more tried and true brand like Energizer. Yes, they work well, yes they basically look the same, but if it's for a professional use case or for something that you rely on, I'd probably stick to Energizer.I will say that If you can get these cheap, I they're worth a buy!

I have used several of them so far and they have worked perfectly. I haven’t tested the entire package, but as of now I’ve had no issues. I am always diligent in updating my reviews when issues arise later on, so I will return to edit my review if I encounter any issues with longevity or if others from the pack don’t work when tested. So far, so good!

I bought the NINMAX® Hyper Lithium AA Batteries to install in “mission critical” items such as the flashlights and the weather radio in my Go Bag. I live in a rural area, and I appreciate the additional level of surety that the things that remain idle for extended periods have available power "for that day."The Ninmax batteries are well constructed. The Ninmax folks used high-quality materials in the construction of these batteries. The true test will come with time and with extended use. As of now, I can not say that installing these batteries in a toy train will make it faster than a speeding locomotive or make my daughter’s toy rabbit leap tall buildings in a single bound or make my son’s toy race car faster than a speeding object.I am counting on the Ninmax batteries having a low annual rate of self-discharge. The package states that the annual self-discharge is 1%. I am also counting on the batteries’ ability to withstand cold temperatures (not extremely cold). Being in a rural area we lose power way too often.So, if the labeling on the box that states “Extreme Cold Endurance Version” is true then these batteries will serve their intended purpose.

I needed some lithium batteries to use in my external weather station for the duration and resistance to low temperature that these batteries offer. As measured on a multimeter, each battery comes in, on average around 1.82v. These come in a standard AA size configuration and fits in my weather station as it should. Because my weather station is exposed to the elements, the manufacturer recommends using lithium batteries that are less influenced by low temperature than standard alkaline batteries. These batteries have all the buzz words my weather station instructions require. The hope is that I get good life of these batteries as it contributes to the transmission of stations data to the receiver inside my house. As it is, these batteries have a robust voltage out of the box and fit standard AA size compartments just fine and I'm happy with them so far.

great for blink cameras

The cold weather is approaching, and I got these for my outdoor wireless thermometers. Since the temperatures in my area dip to -30 degrees at times, it is important that I use these lithium batteries, which hold up much better in cold harsh climates. These have been working well so far. We haven't gotten that cold yet, but will report back here if I run into any longevity issues.
