Mupoer Rechargeable AA Batteries 4 Count,Lithium Battery A 1.5V 3000mWh,Double A Rechargeable Battery,Pilas Recargables AA,Li ion Two A Batteries for Blink Xbox Long Lasting Blue

The unit has quality construction. Operation of lid works smooth with good precision. The charger unit works as advertised and charges all 8 batteries at once or just one battery giving a clear indication of the status of each individual battery being charged. Batteries are all rated for 3000 mAh and seem to hold up well under load but time will tell more on that. Overall, I recommend this unit for anyone who needs plenty of rechargeable on hand.

Anyone who has a Blink Camera knows that Batteries are it's worst enemy. Not only do the Blink Cameras not work well with Regular AA batteries, they need those expensive lithium batteries and the price of those have practically doubled in the last 2 years. The major brand lithium batteries have become so expensive that I was using off brand ones and I always wondered why there were no rechargeable ones. Today I'm singing in the Rain because Now there is. Keep in mind that I bought the 3600 versions instead of the 3000 as that holds 20% more power. I was very skeptical but really hopeful so I bought this and it arrived well packaged. I plugged it into my Fast Charger for my Phone. I've heard people complaining about the charger getting hot, keep in mind that this is going to draw current at the top end so it is best to use a high amp charger like the fast phone chargers if possible. Took a few hours and they were all charged and steady green light. I immediately deployed all 8 into 4 different Blink Cameras and so far 10 days later they are still going strong. Battery indicates OK in the App. Anyone who says they don't work on Blink is simply lying and I would be suspicious of their interests. I knew something was up, when suddenly I noticed that the price of name brand Lithium batteries had dropped significantly recently, I can give you one guess why. There are now alternatives. I will not be surprised if within the next few months suddenly that major brand that owned the Lithium AA Battery market releases a rechargeable one. My own thoughts are if they only last a month between charges I'm totally fine with it, because I've had other off-brand non-rechargeable batteries last only 3 months. I've ordered another spare set so I can rotate batteries while charging without any downtime. The fact that my locality no longer accepts Lithium batteries for recycling and insists that I just throw them in the trash, means that these will be great for the environment. That is another great advantage. For now I'm yet to get a clear timeline on how long they will last but I'll report back on how long they last between charges in an Update. == == UPDATE 12-10-2024 == == Well its been 2 months and my most active camera told me the battery is low. For reference I was changing that camera's battery with regular lithium ones every 5 months with Brand name. I tried those no-name lithium battery I got just 3 months. So these rechargeable last 2 months and I was able to just recharge it again and pop it back in. This is the reason why I bought this in the first place and I'm delighted with it's performance. For my low traffic areas, these are still solid green, so I'm happy. Based on what I've already seen, I would guess these would last 6months to 1 year in low to non-traffic areas, where I would get nearly 2 years.

The battery duration is indeed quite powerful! I always use rechargeable batteries to power some transmission devices but none of those work as long as expected, especially during heat or cold. Until I found this product! The charging takes way longer than some other products, but hey, the outcome comes amazing!

These rechargeable AA lithium batteries work really well overall. They charge fast, and the included charging cable and sturdy rechargeable case are huge pluses. I especially love the charging light indicators, which make it easy to see when each battery is ready to go. The only downside is that the battery life is a bit shorter than I expected. They don’t last as long between charges as some other brands I’ve tried. That said, the quick recharge time and the convenience of the case still make them a solid choice. Great value for the price!

Purchased these rechargeable batteries for my Bose A20 headset I use when flying. Not that the headphones use a ton of battery, but I do get tired of having to buy new ones and throw the old ones out. I was a bit skeptical of using rechargeable ones but decided to order anyways. I am really happy I did, first, the charger is great, just drop the batteries in and close the lid, the LEDs tell you what is going on with the state of the batteries, and they charge relatively fast. On to the batteries, they don't feel any different than a regular battery, maybe a tiny tiny bit larger, but not enough to make a difference for what I am using them for. I put two fully charged batteries in my headset and flew for two weeks with them. I would venture to guess in that time I flew around 20 hours and still had not needed to change them out. My headset was not flashing orange indicating they were low. I am not sure how long they would go past that but will push them to that point in the future. For reference, I usually fly with either Kirkland AA batteries or Duracell and typically see around 8 -12 hours out of a set of those batteries. So longevity seems to be on par or better than name brand non rechargeables. I also keep a back up pair of batteries in my flight bag, I wanted to see if they would lose any juice over time in the heat and being up at altitude and brought back down repeatedly. Over two weeks of sitting in there and going through that, they were still fully charged. To say that I am impressed is an understatement, I am very happy with these batteries and am looking to purchase some AAA ones to keep around the house, if they are anything like these I am sure I am going to be very satisfied.

Recently used 3 of these in a set of Christmas lights only 20 led bulbs with a timer. So they only run 6 hours a day then turn off. And the batteries only lasted a week. So far pretty unimpressed. Was expecting them to last much longer. So the seller was very quick to respond to my concerns. And the answer was. Our batteries are not well-suited for low-power products. But they issued full credit for the product. Due to the quick response upgraded to 5 stars. Not based on the product but on the great customer service.

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!

Primeras baterias recargables que de hecho funcionan correctamente en camaras Blink, creo porque a diferencia de otras, estas si funcionan a 1.5V de manera persistente, no duran tanto como las de litio que recomiendan, pero facil me aguantan 4 meses entre recarga y recarga, se pagan solas considerando lo que cuestan.

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 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.

Works as it should

Convenient, well designed and sleek charging case. User friendly item, Easy to understand. Always have fully charged batteries on hand. Will come in handy for my Blink camera setup. However a couple of batteries were not able to be charged despite several attempts in different slots.
