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 really like these batteries. I like the charging case. The quick charge. But all of a sudden a tip broke off one of the batteries making it useless. This should never of happened. Shame. Update: The seller made things right and I recommend them for this product despite my issue.

It has a very good batter capacity for my Meta Quest 3 Controllers, I have never had an issue with them. I’m glad that I could find something that’s reliable and easy for a good price.

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.

I have used these batteries and charger for over a year now and my only complaint is 2 of 16 batteries have gone bad and refuse to take a charge. I would say these are amazing in cold weather in my trail cameras. One set of 8 were in a trail camera from October through February with temps as low as -2 degrees, took hundreds of pics and short videos, and still had over 85% charge. I'm not happy with the two bad batteries, but otherwise I am pleased with their quality and power holding ability.

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.

I am so impressed with this charger and the fact that you get eight batteries with it is awesome. The batteries hold a charge for super long time. I have it in one of my blink cameras outside. If you’re thinking about buying one, don’t hesitate to purchase this one no need to get a big brand name on me and pay &20 to $30 more. . I’m impressed with three hour charging time and such a convenient size for storage. Definitely no overheating. So all in all, I cannot find a negative thing about this product.

Works as expected. Charges fast and doesn’t seem to get hot. Fits nice in case and products. Overall great value for the money!

I bought one of these 3000mah 8 packs with charger last year from the same vendor. I liked the charger and it has worked great. I'd give that first one 5 stars. (It's the yellow charger in the pictures.) I wanted more of the same batteries, so I returned to the same vendor because I was happy with my first purchase. However, it was more cost effective to just order 2 more 8 packs with chargers. These chargers are crap compared to what I got last year. They look the same at first, but they feel more flimsy and cheap. They require the batteries to be placed differently: one row is positive up, the other is positive down, but there is no marking or indication for this and the contacts look the same for both rows. I marked it for anybody else in the house who might use it. (Old charger was all positive up, and wouldn't let you close it with the batteries in the wrong way.) The biggest issue is that the batteries wobble in their slots. Both of the new chargers have issues with various batteries failing detection because they wobbled and didn't make proper contact. Slapping them around tends to fix one failed contact, but makes another loose. 2 slots in one of the chargers are defective because the spring in the bottom doesn't work to make the battery contact the top side. It seems like they tried to address these charger design failures by providing little plastic battery caddies that you put two batteries into before dropping them in their slots. This also doesn't seem to be indicated anywhere as being necessary, as I first assumed they were just for shipping and nearly recycled them. Using the caddies seems to resolve the contact issues. I never had any issues with the first charger I got. The new design is disappointing a step backward. Now I have to also keep track of a bunch of little plastic parts...good luck in a house with teenagers. I guess that's my fault for not looking close enough and assumed I was getting the same product again. Had I realized this beforehand, I would have probably bought something else. The batteries themselves are batteries. They work fine so far and all of them charged up with no problem.

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!

Convenient and efficient packaging, batteries in charger. Smaller footprint than many rechargers. Solid build. Like Russian tank before Ukrainian drone visits.

Très bonne capacité, chargeur compact. Bon produit

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.

These are the only rechargeable batteries that work in all applications. The 1.5 volt is good and also they last at least as long or longer as any good brand of battery. I do recommend them and will buy them again.
