We purchased these specifically for our Blink cameras and they work great! They recharge fairly quickly and last a good amount of time depending on how active each camera is. We usually have to replace them every three to four months, but if the camera has lots of activity it's closer to two months. The charging case is so easy to use and small so it doesn't take up much space. We've saved so much money on disposable lithium batteries since switching to these ones and we were replacing those at the same rate as these ones. Read more

I had an issue with one battery. It would not take a charge so I notified the product company and they try old me to buy the replacement batteries. After I purchased the replacement batteries they refunded me the replacement batteries money that day. I am extremely satisfied with the batteries and with their product customer service. Thank you Read more

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.

I game for long periods. One pair will last between 16 hrs and 24 hrs. Takes a few hours to charge.. The only thing I noticed was that there was no telling when they were low. Other then that, Damn good set. Read more

Product seems to be exactly as stated. No damage, arrived quickly. Batteries had to be charged, which took about 2 hours. They're being used in blink cameras and seem to be working well. For the price they are a good value as disposable batteries are expensive. Read more

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! Read more
