NECTIUM Superior Performance AAA Batteries 8 Count Alkaline Pure-Gold-Bottom IoT Batteries Ultra Power Long Lasting for IoT Devices Smart Lock

Good product

There are two places in my home where AAA type batteries are very important to me, one being my thermostat and the other being my Amazon Fire Stick Remote. I've used cheaper bargain shop batteries but find that they can leak (as you can see in the photo), run out of power quickly, and/or don't make a strong connection. I find this battery from NECTIUM is superior for electronic use with its gold plated negative pole and design for low consumption on standby. The other BIG PLUS is that their storage life is ten years! The expiration date is clearly printed on each and every battery, not just the packaging that often times is discarded. I consider them a good value for the money as you're getting a pack of eight that won't expire soon before you need them. I've posted some photos and hope that they along with my experience help you out a bit in deciding what's best for your needs. Thank you!

Great power but not the best longevity

These are excellent batteries, they look solid and made with quality materials. With a long shelf life they are definitely built to last. Best of all they work great, I've been using them in a couple of my electronics, a mouse and a blood pressure monitor and they delivered the exact power to run them flawlessly. After a week of usage the voltage remained the same, these will definitely last a while.

I opened these and popped them into a tester. They pushed the needle all the way to the right, which on my meter is good. I don't know if they really will store for 10 years as I will be using them well before that. Only can say that they test fine which is a good start.

I replaced the batteries in my Roku with these, and they are working efficiently. (I use few electronic devices, so I am limited in being able to speak of whether they are higher quality on these than other brands.) Time will tell if they have a shelf life of ten years. I generally use the Amazon brand, and these are quite expensive by comparison. If they really have that lasting power, they are well worth the price - but I had 30 days to turn in my review.

10/21/2020: I put these in a cordless mouse which doesn't have and on/off switch so I'll see how long they last. I usually use rechargeable batteries in that mouse. I'll update this review when they wear down

These AAA batteries are designed to last and I hope they do. They aren't cheap at about a buck each so hoping I don't have to edit this review down the road. They claim to last 10 years in storage. I am trying them out in smart water leak sensors that require constant connection to Wifi so this should be a good test.
