Rechargeable AA Batteries Lithium with Charger,8 pack 1.5V 3000mWh Double A Battery Rechargeable,Long Lasting Pilas Recargables Lithium ion AA Battery with Charging Storage Box for Blink Outdoor Xbox

I gave these rechargeable lithium batteries their maiden voyage in wireless handheld mics on a 6-show event. The mics were often left on for 2 hours+ between use. Plenty of power cycling on and off between performances; each time the display on the mics showed full charge, but this detail may have been deceiving—at the very end of show 4 one of the mics quit. All in all, these rechargeable lithiums are better value than NiMh; the latter would never store full charge with multimeter testing (about 1200-1300) and I would ALWAYS change them between sets. Lithiums will charge up to 1450+, and it was a relief to know that I could go more than a day without charging or changing them for wireless mic use. Charger works well, and the whole kit with 16 batteries and charger takes up very little real estate in transport and is very portable.

Update: I’ve been using these batteries for a couple of weeks in all of my cameras. I think they’re pretty great! I’m getting anywhere from 4 to 5 days on my high usage cameras, 2 to 3 weeks on all of my other cameras. This is the same battery life I was getting on batteries that were costing me double this set each month. Ordering another set now! Finally! Rechargeable batteries that work with Blink Cameras!! Buying batteries isn’t cheap. I was spending anywhere from $35-60ish a month due to a couple of my cameras having really high usage. I have 6 Blink Cameras on my property where my shop and vehicles are located. These arrived today, and took about 2.5 hours to fully charge. I don’t know how much battery they had upon receiving them. I’ve installed these batteries into 2 of my cameras, and as of right now all seems to be good. These two cameras get the most motion, so fingers crossed, these batteries will hold up well! I popped the new batteries in, screwed the back on, stuck them on their clip and went right to the Blink app and was able to view live right away on each camera with no connection issues at all. They come in a nice little black storage/charging case.

It's been a LONG time since I bought rechargeable batteries, but I wanted batteries dedicated to my game console controllers, among other things. The old one I had required to be plugged into an outlet. These are charged by a cable (which it comes with), likely mostly everything else these days. I love that everything is contained in this little 'treasure box' of batteries. It comes with eight batteries, totally filling up all the slots. What I received is exactly what the picture shows. So far, the batteries are compatible with everything I put them in. They have been put in toys, lights, Xbox 360 controllers and Wii controllers , all which worked fine. The life of the battery is as expected. While I didn't run controlled tests on life, they last just as long if not longer than new, regular batteries. There is no wasted space and is the perfect size. In addition, I love how it chargers. You can watch it charge. However, please read the directions. You do NOT want to keep charging it if they do not need it. In other words, don't keep the batteries in the unit and keep charging indefinitely. The instructions have specific instructions. For me, it works completely because I don't like to leave things plugged in anyway. There was thought in how it charges too. It shows how many batteries are being charged (in my video below it shows two), and has a nice light that's not distracting but informative. I detest lights that look like they are trying to signal planes how to land. These lights do not draw unnecessary attention. The value for the money is spot on. Good, quality, rechargeable batteries have never been cheap, and I found these quite affordable. If they were any cheaper, I would be suspicious. I just wanted a dedicated set of batteries for the game consoles, and the 'treasure box' storage and battery life make this a perfect match. The fact that its both storage and charging makes it quite a grab!

I confess that I did not buy these for any particularly scientific reason. I bought them because I needed rechargeable AA batteries, they came with a rather clever charging/storage box, and—most importantly—the word MUPOER on the packaging looked, at first glance, remarkably like MUPPET. For the benefit of American readers, in England a muppet is not merely one of Jim Henson's felt-based entertainers. It is also a technical term meaning a person who has just done something spectacularly silly. As in: "You put diesel in the petrol car? You absolute muppet." Consequently, purchasing electrical equipment apparently manufactured by Muppet struck me as either a terrible idea or an excellent opportunity for product testing. Fortunately, the joke appears to be entirely in the name. You get eight 1.5V lithium rechargeable AA batteries rated at 3000mWh, together with a compact charging case. The case itself charges over USB-C, which is vastly preferable to having yet another peculiar little wall charger lurking behind the furniture waiting to be rediscovered in 2037. The manufacturer claims up to 2,500 recharge cycles and roughly three-hour charging with a suitable power supply. And, rather annoyingly for someone hoping to write a devastating review about batteries made by Muppets, they work. They charge. They hold a charge. They power things. The little box keeps them together instead of allowing loose AA batteries to breed mysteriously in the kitchen drawer. This is all deeply inconvenient from a comedy standpoint. I particularly like the fact that these are 1.5V lithium rechargeables, rather than the more usual 1.2V NiMH variety. That can make them rather more suitable for devices which become sulky when presented with the lower voltage of conventional rechargeable cells. Mupoer specifically advertises them for things such as Xbox controllers, cameras, toys and some Blink devices, although it warns that they aren't suitable for every application and specifically says not to use them in smoke detectors. The charging box is probably my favourite part. Eight batteries and one USB-C cable goes in; electricity happens. No loose cells, no sprawling charger occupying half a power strip, and no archaeological excavation required when you next need four AAs. So, regrettably, I must report that MUPOER is not actually MUPPET, and the product itself appears to have been designed by people who know perfectly well what they're doing. This is disappointing. I had the headline ready and everything. Five stars. Mister Twiggly P.S. The bear in the photograph has inspected the charger and found no obvious faults. His electrical qualifications are, admittedly, limited.

Solid battery's with a very convenient charger. That is to say, the entire thing is great for bring the batteries from 0 to 100 however I would not treat these like earbuds. My hope was to keep these under my desk and plug them into the wall indefinitely however after 30 minutes, they got warm. After an hour, a little on the hot side. I let them cool down and realized that I won't need to do that necessarily. They're good batteries with a long enough life that at least for my use, they charger is done long before I need the next set. anyways, I only mark the one off because of the fact you can't really leave these plugged in for long long sessions at a time and you're limited to that. it's only been a short week so I cant comment on compatibility with new batteries yet or how they are to replace or if it connects to your phone and charge off alternative sources but overall I'd say they're worth the purchase

These rechargeable batteries are very convenient and easy to use. I like that the charger keeps everything together and makes recharging simple. The batteries fit well in my devices and have worked reliably so far. It’s a practical option if you use AA batteries often and want to avoid constantly buying disposable ones. Very useful for everyday use.

All of these are basically clones, but still solid, reliable batteries. I have at least 3 sets in the house, gaming with an Xbox controller you'll see maybe 10 hours of straight gameplay before needing to swap. Charging takes about 2 hours, but you can charge with some missing. Charge them when you're on the last pair and youre good to go!

So the batteries and charger overall were pretty good in terms of form, function, and appearance. The only problem I have with them and I maybe being unreasonable, but they don’t seem to have a very long drain and recharge cycle lifespan. I use them for a smart door lock. Well recently they don’t have enough amperage to operate that door anymore. Maybe these are better suited for a tv remote or an alarm clock. But not necessarily for door locks. Now I wouldn’t complain but the lock takes 4 batteries, so if half of them went bad and i had time to replace them i’d be ok with that. But all 8 became “weak” at the same time. So now my smart door lock is a dumb door lock till i get more rechargeable batteries or buy a different brand/quality set and charger.

Tengo una chapa electrónica que consume una cantidad increíble de pilas, por lo que las baterías alcalinas no eran opción económicamente viable. Así que le puse baterías de NiMH, pero estas duraban apenas una semana, y a lo mucho dos, si yo operaba manualmente el seguro en la medida de lo posible. Pero la verdad era una medida ridícula, pues si de usar manualmente la chapa se trata, mejor usar una mecánica. Así fue como llegué a estas baterías. Leí comentarios acerca de su larga duración, y decidí probarlas. Es impresionante lo mucho que duran. Pasé de una semana con uso normal, a un mes completo! Y sospecho que todavía les podría sacar una semana más de carga, solo que la chapa ya empezaba a abrir con lentitud, así que decidí recargarlas ya. Si lo que quieres es una batería recargable, pero que dure tanto como una alcalina, esta batería es la única opción que conozco. Una nota adicional es que supuestamente durará más después de unos 5 ciclos de carga. No puedo atestiguar acerca de esto, pues apenas las he recargado una sola vez, pero si es verdad, entonces la carga de estas baterías es realmente brutal! Cargador: a este precio, pocas baterías incluyen un cargador. Y el que tienen estas es una hermosura. Es un baúl muy finamente realizado, que tiene un led indicador de carga de manera individual para cada batería. La tapa tiene un magneto que la hace cerrar y abrir con facilidad. La entrada es USB-C, e incluye el cable! La única desventaja es que no carga tan rápido como dicen. De hecho, en vez de tres horas, tarda cinco. Pero no me parece mal, sobre todo considerando lo mucho que dura la carga. Es bueno que incluyan el cargador, no sólo porque obtienes más valor por tu dinero, sino porque estas baterías no deben introducirse en un cargador para pilas de NiMH. En cuanto a la durabilidad, no tengo modo de saberla todavía, pero los componentes se sienten de calidad. Considerando todo, no volveré a comprar baterías de NiMH. Estas son las mejores recargables que he comprado jamás! Compré la versión de 3000mAh. Hay una versión de 3600mAh, que probablemente sean aún más formidables! La diferencia de precios no es mucha, así que probablemente valgan mucho la pena!

Le meilleur achat que j'ai fait , charge très burn , rapidement et tienne la charge , excellent produit 10 sur 10

Estas baterías de Litio son muy buenas, te mantienen el voltaje a 1.5 de forma constante. De hecho esto es una ventaja del Litio, que yo como dueño de un Tesla puedo constatar, a diferencia de las de NiMh que su voltaje baja dramáticamente a 1.2V, inclusive inmediatamente después de cargarlas. Por qué es importante esta entrega de voltaje? Porque hay dispositivos que lo requieren. De hecho son todos aquellos dispositivos que te recomiendan utilizar baterías alcalinas pues esas también entregan los 1.5V. En mi caso tengo una chapa electrónica Nest Yale lock que utiliza 4 baterías AA. Google Nest indica no usar baterías recargables y es por la misma razón, porque la mayoría de las baterías recargables son de Niquel (NiMH). Afortunadamente existen estas baterías AA de Litio recargables que entregan el voltaje requerido. Usando yo baterías de NiMH en la chapa inmediatamente me advierte que las baterías se van a agotar, derivado de la falta de voltaje. Tan pronto reemplacé las NiMH por estas de Litio la advertencia desapareció, la chapa funciona correctamente. Complementaré esta reseña con respecto a la duración (capacidad) de las baterías. Yo esperaría que me duren lo que me duran las alcalinas, unos 4 meses. Ya les contaré Actualización La carga me duró 3 meses en vez de 4 de unas alcalinas Duracell. No estuvo mal. Dos horas de carga y tenemos para otros tres meses. Fin de actualización El cargador es elegante, parece mas un estuche que un cargador. Los LED son super intuitivos y tal cual plug & play (charge) Como dueño de Tesla, recomiendo no dejarlas cargando todo el tiempo ni descargarlas por completo – lo ideal es mantenerlas entre 20-80% para alargar la vida. Hablando de duración, la especificación dice 2500 ciclos. Si cada carga dura unos 4 meses (mi estimación para el lock), teóricamente serían 10,000 meses (~833 años), pero en uso real con cuidado, podrían durar 6-8 años (o 2500 días si las usas por completo a diario). ¡Una inversión sólida! Nota: Verifica compatibilidad con tu dispositivo antes de usar.

Me encantan! Son muy prácticas y te ahorras la molestia y el dinero de estar comprando pilas a cada rato. Además duran bastante!

These work amazing and keep charge for a long time depending on your application. They also charge relatively quick.
