HixonRechargeable Lithium Batteries AA 3500mWh High-Capacity,Constant 1.5V Rechargeable Double A,1600 Cycle AA Li-ion Battery,Max 3A Current[8AA+1Charger]

I have changed all my AA, AAA, batteries over to rechargeable Lithium batteries. These have similar specs, Voltage, & Current characteristics to Alkaline batteries, & can be charged over, & over again. These in the long run are less expensive than disposable lithium batteries, & these do NOT leak, like Alkaline batteries do. I have had too many Alkaline batteries leak, & damage the item they are in. I will NOT buy alkaline batteries again. These Hixon rechargeable Lithium batteries seem well made, & come with a charger that works for AA, & AAA lithium batteries.The instructions say to only use the same brand batteries and chargers. I am slowly integrating these batteries into all the devices I use AA, & AAA batteries. If they last, which I believe they will, I highly recommend these. The chargers work great, & the individual batteries even have a blue LED in the battery that light when they are being charged.These are the same voltage as alkaline batteries.Nickel Metal Hydride batteries are 1.25V which does not always work the same as alkaline, or disposable lithium batteries. This will save you $$ in the long run, & they seem to last as long as disposable alkaline batteries, per charge.

These batteries are being used to power a ROMI robot, an aide to programming using FRC's WPILib environment. When fully charged these batteries output 1.5 VDC, and that output remains constant until nearly fully discharged. In contrast, Ni-Mh batteries only output ~1.3 VDC when fully charged, and they decline from there until effectively exhausted at maybe 0.9 VDC. The higher output and the better consistency from Li-Ion batteries is very beneficial for this application, especially for tuning PID control loops. Varying voltages will change the robot's response, making control loop tuning frustrating.Of course, other brands of Li-Ion batteries should provide the same advantage, if of equal quality, but I cannot comment on them because I only have experience with these Hixon AA 1.5V batteries, for which I have been and remain very satisfied. I would recommend them for any use benefitting from a consistent portable voltage supply.The first buy was made in June 2021, and the latest buy (to support a 2nd ROMI) was made in Nov 2023. Both purchases consisted of 8 batteries plus charger. For both orders all batteries received charged perfectly, and to date the batteries from the earlier buy have been through over a hundred discharge/charge cycles without any failures. Hixon's charger was used exclusively. Regarding battery life, the runtime in a ROMI is maybe 1.5X the runtime provided by 1900 mAh Ni-Mh eneloop brand batteries, but with the advantage of consistent performance. One disadvantage of the Hixon charger is that it only holds 4 batteries, but with two I can now utilize both in parallel, very useful since a ROMI requires 6 batteries. Even though relatively expensive, to me, these Hixon batteries have proven their worth.

I have seen no measureable decline in the battery performance or the charger in the last 18 months of use.I have vanity lights, spotlighting various figurine and movie posters. The vanity lights take 2 batteries and last aboiut 4 days, when I see them out, I grab the next set of batteries out of charger and change them out, and put the batteries drained batteries back on charger. This has gone on for 18 months, with the batteries either in the charger or in the lights.

These batteries work really well and have excellent capacity. They charge quickly and after many cycles are performing wonderfully. It’s important to know that the charger they come with can only charge these specific type of cells. Further you cannot charge these cells in a standard NIMH AA charger.When looking over the available types of lithium ion AA batteries that use an internal voltage converter like these two, I very much prefer the type that charge from USB directly so that you can still recharge the cells if you can’t find the charger they came with.If you are confident you won’t lose the included charger, then these are perfect.

Works great with the medical device I use. Over the life of the battery it will [ay for the battery serval times.

So I have mixed feelings on these. I needed 1.5V batteries for my Original Blink Outdoor cameras.It first worked out of box for one of my cameras, then it lasted like half the time compared to the one time use 1.5V energizer batts that were still going strong in my 2nd camera.I then notice cameras not turning on or connecting for live view and thought may be the Blink cameras themselves. Buy now I have concluded it may be the batteries causing this.Because I tried fully charged hixons on the new Blink Outdoor 4 camera and the app wouldn't add the camera. When I plugged it in with the power cable and adapter, the app updated and added the camera, live view even worked right away.Again with these Hixon batteries installed, the camera fails to start live view and sometimes would go offline. The camera doesn't ever work with them, I put provided Energizer 1.5V lithium batteries in and it loads right up.I concluded that these batteries may be a hit or miss, maybe even faulty. I have one set installed in one camera and it usually loads, another set in another that always fails loading live but is online. And a third and fourth set trying to install on the Blink Outdoor 4 that never worked. These 3rd and 4th sets were used in the two older Blink Outdoor camera previously as swaps.I wouldn't recommend these if you need 1.5V for sensitive high powered equipment. May work better for flashlights or remotes.I even bought a new set with charger for the Blink Outdoor 4 and same issues. I am definitely returning those. I'm out of luck on returning this set since I had it for more than 6 months and used and charged maybe 4 or 5x. But just now realizing the issues.

Battery where use for radio-

26/Nov/2024:This helped me with devices that require 1.5V to operate where rechargeable NiMH batteries only provide 1.2V and failed to operate.Now I can save buying disposable alkaline AA batteries.Keep in mind the charger is for the provided 1.5V AA lithium ion recharble batteries. DON'T use NiMH batteries with this charger or the 1.5 lithium ion batteries with NiMH charger.There is one charger available compatible with both XTAR BC8 since XTAR is another 1.5V AA batteries manufacturer which I also recommend.I will update if I got any issues with the product.

These rechargeable AA batteries offer impressive 3500mWh capacity, providing long-lasting power. The USB-C charger is convenient and fast, though charge retention could be better over time. A solid choice overall and great that its 1.5V so works in high power devices like battery video doorbells and RC cars

My TV remote malfunctions and drains battery so fast. It needs alkaline batteries. I gave up buying many alkaline batteries and tried these. These batteries last even longer than alkaline batteries. Highly recommended.

البطاريات صراحه ما شاء الله جداً ممتازه استخدمتها لكنترولرات الفي ار كويست 2 جلست معي 21 يوم استخدام يومي 6 الى 7 ساعات تقريباً

Très satisfait du produit
