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 thought the battery charger was dead on arrival. The green lights continued to flash and the batteries were never charged to a measured voltage greater than 1.38V. I was able to charge the batteries with another charger. Before deciding to return this, I realized that I had a faulty cable from the power source. The current was enough to light up the lights of the charger, which continued to blink, but not enough to charge the batteries. So in the final analysis, the charger was fine and the batteries are fine.

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.

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!

Not too bad. They are pretty good except two batteries that only worked for one use. Now those two won’t take a charge at all. Only had them a month. Only used them in an Xbox controller. All the others are fine n used at least a couple times. Praying the others keep taking a charge as I planned on using them in my blink cameras in rotation. Can’t return them because my 30 day period just passed. :( Edit: the sellers contacted me and replaced the faulty batteries. (With better ones) they work great. So now I have the full set again n very happy. After using the batteries for a bit now n recharging them a few times, they last a long time. I’m impressed. Great customer service. They have been very helpful n great communication. I would definitely recommend to others and I’ll be ordering more myself in the future now that I know they work great. Btw. The charging case is great n it doubles as a case to pack n carry them on trips.

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!

UPDATE:: seller reach out , sent more. Made the purchase right!!! A couple of the batteries will not take charge. Husband had to trash them. Couple others will not hold a charge for long.

Funcionan de manera excelente, recomendado!

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!

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.

I bought these rechargeable batteries to use in my Blink cameras. The high mAh and the enclosed charging case were sustainable features that drew me in. However, these batteries do not last very long at all outside in my cameras. I am not sure if they can't handle the cold temperatures, but they aren't even lasting a month before needing to be recharged. I have purchased this product twice because I have a large number of Blink cameras, each purchase 1 of the 8 batteries would not hold a change at all and were defective. What appeared to be a great idea and sustainable purchase has lead me back to using single-use batteries.

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.
