NINMAX® Lithium AA Batteries 12 Pack, 3500mAh 1.5V Longest Lasting Double A Battery【Non-Rechargeable】

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.

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.

These batteries are of a higher quality rating than standard batteries, being able to withstand lower temperatures. BUT, you'll pay a pretty penny for them. These are good for items that need batteries than aren't kept in a climate-controlled environment, like things in the garage or outdoors. So far, I'm happy with the performance and no complaints. I'll update if things go downhill the colder it gets outside. If not, all is well!

These batteries seem to be good. They claim they are longer lasting and for extreme environments. I don't know how long they will last, but I will update once I have used them for a few weeks. I've never heard of "hyper-lithium" batteries, so I'm hoping they will work really well in my game camera.

I put these lithium batteries in a biometric lock because I am confident they will last an extra long time. My battery tester showed that they were indeed 1.5V. They look and install great. I don't know what else to report, until they finally die down, to give a report on lifespan. But so far, so great. I wouldn't hesitate to buy more of these or to suggest this brand. It seems like a good value to me.

I got these for some of my outdoor decorations for the Halloween and Christmas that tend to burn through batteries quickly. They are doing great so far, keeping the lights bright on colder nights. We have not gotten a frost yet, so we will see how they manage that, but it has gotten into the 40s and no issues. They are a bit pricey even for lithium batteries.

They are batteries and they work. Let's see if they really last longer than the standard ones. I'll update the review after they are exhausted.

I am using these batteries for my outdoor surveillant cameras. The package came with four AA batteries in plastic wrap together. The outdoor temperature at night can drop below freezing so these batteries are perfect for the environment. They are rated at 3500mAh so it can last a long time. I like the fit and finish of these batteries and I highly recommend this product.
