NINMAX® Lithium AA Batteries 24 Pack, 3500mAh 1.5V Longest Lasting Double A Battery for High-Tech Devices【Non-Rechargeable】

I'm a guitarist and use these in my wireless transmitters. Normal alkaline batteries and rechargeables last about 6-8 hours. I've been using these freaking things since December 23, 2023 in 3 different wireless units! They JUST finally died 2 Saturdays ago! The only issue I have is, my battery meter on the wireless has a tough time reading how much time is left on these. When I started my show 2 weeks ago, the batteries were reading 10 hours....the highest number you can get....which it's been reading since December 23. In the middle of my set, my meter started blinking which means "change those batteries as soon as the song is over." Normally, you get an alert and see how much time you have left. Not with these. They last forever, but when they die, you have a matter of minutes before they totally die. Just be careful.

These batteries have the power to effectively operate my Blink cameras.Just what I needed.

I have used these in several different things and some cheap thunderbolt batteries from harbor freight work better for a fraction of the cost. Bought these to try and use in the blink cameras and they only last a few days. I figured ok I will use them in some of my kids toys. Nope half don’t even have enough voltage to turn on. Complete waste of money. If I had not used several of them in different things I would try sending them back and buying the energizer. Edit: Seller sent another pack to try out. Still did not last as long as others I have tried but definitely worth giving another try. Will probably ordere and give another try

I use these in my door lock and flume water monitor. So far they last at least as long or longer (6-8 months) than the energizer lithium batteries I was using at a lower price point.

These are great! Much cheaper than the big brands and with faster charge times too!

These were a huge waste of money. I 100% do not recommend. It’s like almost the whole pack, except for two batteries, arrived already dead.I bought this pack just over a month ago for use in outdoor Blink cameras. Only one camera has stayed online since inserting these batteries. Literally I put in a pair of these batteries in one camera this week, to replace another pair of these that died weeks ago, and yes, the camera did come back online - but registered that the batteries were low - and they were dead less than 12 hours later. I only wish I had not been so busy with other things, so I could have kept replacing as soon as they died and then still been within the Amazon return window to send these back. I kept thinking “it must be me” until the two I tried this week that had not enough juice to last even through the next day. This has been one of the worst products I’ve ever bought on Amazon. Very unsatisfied! I would rate this Zero Stars if I could.

DOA-Dead On Arrival- Haven’t had these batteries long. Iv already experienced 3 dead batteries out of 12 used.- Amended. After receiving the review that I left the company reached out to me and made my problems right. I did have a bad couple of batteries, but they replaced them free of charge. I must say their customer service is on top of things. Giving them another chance. So far so good.

Exact need for my Blink

5 out of 5 Stars (5)⭐⭐⭐⭐⭐[TL;DR][QUALITY] (5/5)[VALUE] (5/5)[EASE OF USE] (5/5)[MET EXPECTATIONS] (5/5)[PACKAGING] (5/5)[REVIEW REMARKS]Perfect for the Blink®️ doorbell camera. This camera historically gobbles batteries.I ordered these because they are Lithium AA, which is required for the doorbell camera.So far, they are lasting longer than a FAR MORE EXPENSIVE national brand. They have been in the doorbell camera for approximately 3 weeks now and they are still showing as 'OK'. Comparing to the 2 week cycle the other brand, that was double the price, lasted. I think these are doing a decent job.At the time of ordering, this 4-pack of AA Lithium batteries were $12.99, which is an excellent value - especially when there are enough batteries for two cycles. I am interested to find out just how long these will last. At the time of writing this review, NINMAX batteries have outperformed a major national brand. Is this a big deal? Maybe. Time will certainly tell.All in all, it would seem I am ALWAYS changing the batteries in my Blink®️ doorbell camera. However, there is not a time benchmark expectation of performance. The lifespan is all over the map, depending on temperature, settings, connection to the network, etc. However, I made all the recommended changes to the settings to maximize battery life, four battery swaps ago. So, this set of batteries are working on the same settings as the major brand, and it has outlasted, thus far. I am very happy not to have to change the batteries all the time. I am hoping I can get at least a month or more from the battery life of these NINMAX batteries. I will update this review in the event they do not meet this benchmark. Recommend based on life expectancy in our doorbell cam up to now. It is a nice change. Your mileage may vary based on your use case, but I am happy with them so far. Order with confidence.In the event that experiences change or evolve, updates may be made to this review to address such developments.

First of all, you should understand what you are getting. These are NOT RECHARGEABLE batteries. However, among non-rechargeable batteries, alkaline ones are better than carbon zinc ones, and lithium ones are the best, better than alkaline and carbon zinc ones. And normally, those three types of batteries are priced accordingly.The most important advantages of lithium batteries over the other two types are that they last longer, but mor importantly, they keep their power levels stable for a long time. Simple devices such as TV remote controls do not require a lot of power or do not get affected by power fluctuations, so you can use cheaper batteries with them. However, if you are using electronic devices that require more stable power, lithium batteries will work the best. Even if the batteries might still have power left in them, the fluctuations (or drop) in their output power can render them unusable for such devices. Despite their more expensive prices, lithium batteries can be more cost-efficient in such cases. And if you are using batteries for professional work, you would want to make sure you won't need to change batteries too often.As a result, you have to evaluate your use case, and pick your batteries accordingly. These are definitely for devices that require more power, that require power for a longer time, or that require the power levels do not drop. Those are usually more sophisticated devices.These batteries work fine, but I have not had the time to evaluate their lifetime yet. More importantly, I have not been able to test what happens to their output after a long time. However, despite having a fairly unknown brand, these are supposed to last longer and maintain their output levels until the end of their lifetime.One thing I will complain is that while the product page mentions in several places that they are 3500mAh batteries, that is not mentioned at all either on the batteries themselves or their package.Overall, these seem to be powerful batteries that are worth their price, but only depending on your use case. For simpler devices and energy requirements, these would be an overkill.

I'm using these in a small flashlight that I use when I need to get behind something or I'm in a tight space. Been using them for a while but quite sparingly as I haven't had the need. I've had this little light for a few years and it seems to be working as it always has with the name brand batteries I would normally use.

Lithium AA batteries works incredibly well for high drain devices like cameras, door locks, and wireless game controllers. It can last anywhere between 4x to 6x longer than alkaline batteries and hold power for up to 20 years in storage. My non-wired Nest Protect smoke alarm has been running on the original set of batteries (Energizer Lithium) for the past 6 years. I like that Lithium batteries are able to maintain full voltage until the end, while Alkaline batteries reduce voltage output throughout its lifespan. They also perform better in extreme temperatures (-40F to 140F).These Ninmax batteries have exactly the same length as a regular AA battery. I read a comment saying they were longer but that's not true. The Ninmax has a flat negative while a Duracell alkaline battery's negative is bulged. It pushes 1.76V out of the box which is quite a bit higher than the 1.6V we normally see with Duracells. I plugged these into my UltraLoq smart lock and it worked fine. Regular AAs last about 4 months with this lock, so my expectation is that the Ninmax should give me 1 to 1.5 years before it runs out of charge. I'll report back if it doesn't perform.The one concern I have is that it costs about the same as a 4-pack of Energizer Ultimate Lithiums, which are proven front-runners. If given the choice, I think it is obvious which one I would pick.

Durée de conservation très longue!Le testeur indique qu'elles sont bonnes et elles fonctionnent très bien jusqu'à maintenant dans ma souris ainsi que ma télécommande.Reste à voir si elles seront durables, mais pour l'instant, je suis très satisfait.
