Lithium AA Batteries 96 Bulk Pack, 3500mAh 1.5V Longest Lasting Double A Battery【Non-Rechargeable】

Testing the battery's voltage with a battery tester or DVMM is fine if you're trying to establish the output voltage. But the real test is when you check these batteries in a load-tester device. I keep all my batteries refrigerated and each battery container includes at least one or more humidity absorbent packets. I bought two, 8-count NinMax AA Lithium packs of batteries back in NOV 2023. When I received them, I left them in their boxes and immediately stored them in a Ziploc baggy along with several moister collection packets. I’ve been storing all my batteries that way for years. Then, when I went to use the new Ninmax AA Batteries recently, I first measured the voltage. The 4 new Lithium AA batteries that I got out from the NinMax package measured 1.77 Volts with my DVMM. However, I then tested all four AA batteries on an MBT-1 Battery Load tester and found that ALL 4 tested between 65% and 40%! The batteries advertised as having a long shelf-life and I felt that even though it had been almost a year before I opened the pack to use them, they should have been perfect because I had them stored in a refrigerator. I was disappointed with the Ninmax load test and blamed the battery’s quality for the poor load-test results. In fact, I wrote a review of the battery and noted the results of the load test. I also gave the batteries a low, 3-star rating. However, I later found out that when it comes to non-rechargeable, Lithium batteries, placing them in the refrigerator is exactly what I should NOT do!! Among the information I found when I researched the proper storage method for non-rechargeable Lithium batteries, was this statement: “Putting fresh, non-rechargeable lithium batteries in the refrigerator will not extend their shelf life; in fact, it is generally considered a myth and can potentially damage the batteries due to moisture condensation inside the fridge, so it's best to store them at room temperature in a cool, dry place”. Even though I did have moister-absorbent packets in the bag with the batteries, I must consider the fact that I may very well have caused these batteries to become weak by the way I had stored them. Therefore, I felt I should retract my earlier 3-Star review and offer my apologies for my ignorance to Ninmax. I feel must accept the blame for the poor load-test results as being due to incorrectly storing the batteries. I also must revert my product review to reflect 5-Stars, giving the fact I may have caused the poor results that I measured. Rich

lasted a long time outside in weather station one thing lithuim batteries when they go dead they run something and all of a sudden they stop working thats with all lithuim batteries

3 MAY 2025: Undoubtedly one of the WORST purchases I have ever made. TWICE, NINMAX LITHIUM BATTERIES have failed in 1-3 months in my BLINK Security devices, unlike the COMPETITOR LITHIUMs that lasted 1.5 years. Company will not respond, and Amazon needs to STOP recommending this low-quality item. Vendor communication is non-existent. NOT WORTH IT-USE COMPETITOR TOP-SELLING BRAND INSTEAD! *Other Prime members report the same issues!* UPDATE 5 MAY 2025: Although I was displeased with these NINMAX Lithium batteries (twice they have failed me), I do appreciate the seller sending me a response, apologizing for the defective products and agreeing to reimburse me for the costs of my most recent NINMAX battery purchase. I will now purchase only Lithium batteries from NINMAX's major competitor, but the customer service did make up for the poor product. Due to the Seller's IMPROVED customer service, I have UPGRADED my previous LOW RATINGS to GOOD RATINGS.

Works great!

These were a lot less expensive than the Energizer Lithiums that they were replacing. My Nest Protects require lithium batteries, so we will see how well they hold up. If they don’t last as long as the others, then it doesn’t matter if they are less expensive.

NOT "long lasting" at all. I (unfortunately) bought a 24 pack of these as well as triple A of the same brand because user reviews were good, and the price was less than others (despite the off-brand.) I thought they would be better than alkaline and worth the increase in price. My wife was anxious to try them in a small led motion sensor light, and it took 3 batteries. It did not go even a week before starting to dim and then of course went out. The light is only activated when our cats go to eat at there little cubby, and we do not refrigerate the batteries. Rechargeable Alkaline batteries actually did as well as these "lithium batteries". Either they are old, or just cheap....or both. Will not buy this brand again.

Great battery for the price.

I replaced the batteries in the Blink doorbell camera and they lasted 1 Year and 9 months. Doorbell is located in central Florida and faces East.

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.

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.

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 out 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 and 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.

This is my first time using this NINMAX brand Batteries so I didn't know what to expect. On the surface these batteries look similar to Energizer and other name brand Lithium Ion Batteries. I have used other brands of Li-ion batteries in the past and have found them to be longer lasting than any type of alkaline or rechargeable battery. While I cannot determine the longevity of these NINMAX batteries I can say they measured 1.81V right out of the package so they appear to have good voltage right from the start. Most alkaline batteries will measure around 1.6-1.65 volts when brand new so these NINMAX battery have a little extra voltage right from the start. Li-ion batteries are also slower to discharge so based on the starting voltage these should definitely have a longer life cycle. With there longer shelf and battery life Li-ion batteries are more expensive but in the long run can be cheaper depending on the useage and device. The one application I found Li-ion batteries don't do well in is Cold Weather Applications. If still use alkaline batteries for my door locks and other devices that are out in below freezing weather. Li-ion batteries tend to drop their voltage quickly when they freeze. Overall I'm happy with these batteries. They look good and so far the performance is outstanding. I will come back and edit my review if needed. These are a few dollars cheaper than Energizer Li-ion batteries sold locally.
