4AA Batteries &Charger

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.

These charge quickly and can power a Game Gear for more than 8 hours, which is longer than most alkaline batteries. They are not for every application, however. In particular, I would not recommend them for AM radios. The voltage regulator inside the batteries generates a small amount of radio interference in the AM band - enough to affect the radio they are installed in, but not enough to affect other nearby radios. They are also not the best choice for devices that draw a very high amount of power or get hot, such as high-power flashlights. I have already had two go bad from being used in a 2000 lumen LED flashlight. That flashlight draws a lot of power and produces a lot of heat, so I'm not going to fault these batteries for that or take off a star. Overall, these are a great choice for most applications, but for radios and high-power applications, Ni-MH, Ni-Cd, or Ni-Zn batteries are a better choice.

High quality rechargeable 1.5v lithium battery. I bought EBL rechargeable lithiums and my blink cameras quickly showed a low battery warning. The EBLs clearly don’t maintain a steady 1.5v output under load. These Hixon batteries do very well. My camera settings are not very “battery life” friendly and these are holding rock solid. No low battery warning. There are third party tests online that confirm these batteries output 1.5v very steady, which is required for blink cameras to operate correctly.

Bought them to replace some NiCad batteries in some outside lighting that use solar to recharge the battery. They worked for a day but then not. Multimeter showed almost zero charge. I'm guessing it's a compatibility issue so not a problem with the product but more with compatibility as I mentioned. So I'll use them in my camera flash. They charge fast so they should work out well.

Fully charged two batteries last several months in my cameras very high traffic cameras

Very good batteries and seem to hold a charge for a lot longer than standard batteries you buy in the store.

Great customer service. I had an issue with 2 batteries. They reached out and promptly said they were replacing the def batteries. You can't ask for better service then that.**** I had high hopes for these batteries for door locks. The cinstant 1.5v is nice its actualy about 1.54v. However my lock stopped working in abkut 3 weeks. I checked the voltage and found 2 batteries were still at 1.52v. Great, but 2 were at 0v. Not good. Why did 2 of the 4 die while 2 still had full.charge. i tried to charge the 0v batteries but no luck. Seems they are dead. Now i have 6 batteries out of my 8 pack and my lock takes 4. I cant swap a set out like i planned. When the locl dies, ill have to full charge the batteries or buy more to ha e a 2nd set of 4. That defeats the purpose of buying an 8 pack. I hope more dont die as well.

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.

Excellent

ممتاز

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

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

Le chargeur fonctionne bien, on peut aussi charger seuleument 3 batteries si ont veut. Les piles durent longtemps, on verra si elles peuvent faire 1000 charges .
