Panasonic K-KJ17MZ104A eneloop Power Pack; 10AA, 4AAA, and Advanced Individual Battery Charger

These batteries, and the charger are clearly the Tesla of the rechargeable market! Sleek lines, and modern colors, melded with high performance make for a smooth and carefree experience. I first bought an eneloop battery kit about a year ago from Costco, and I fell absolutely in love with them. They are long lasting and have not given me any of the trouble that some of the older rechargeable batteries are liable to give. These are new fourth generation batteries, with all the technology and extras that one might expect from the modern era. They are extremely long lasting, and although I haven't counted the cycles that I've used, I have no trouble believing that they'll make 2100 cycles in their lifetime. And, after 5 years of use they will still have 70% of their life left which is a big wow if anyone remembers those old batteries! Other nice features include individual battery charging. There's nothing more annoying than having to charge two, or worse four batteries all at once! This charger has engineered it's charger logically so that every battery is charged by itself on its own circuit individually, with no waiting or searching for another battery before you can charge that third one. With all of these features, you might think that there is no room for more, but wait, automatic safety turn-off in case of battery reversal, or over charging! And little LED lights that turn off when your battery is full. The only thing I really don't like, and I guess there had to be something, is the fact that the lights indicating that they need to be charged, are green. Yes green ,the color that means “go”, or” good”, or “hey, it's time to take me out, right”?! No, green in this case means “nope, we need more charging please!” Ah well, I guess nothing is perfect;)

My go to battery for years. Great for any type of gadget or toys. You will probaby need to charge more often than using a standard battery life, but the cost saving over the life of these makes it a no-brainer choice for an environmentally and economically solid choice.

These are excellent batteries. The included charger is not fast by any means but it is very good. It slowly charges the batteries and they barely get warm to the touch. I especially love these in flashlights and headlamps as their power curve provides bright light until the batteries are almost dead. About the only thing that could have been improved was the directions for the charger. A light under the battery means it is charging, when the light goes out the battery is done charging. If you see a blinking light that battery is bad. This wasn't clear to me from the instructions. I had some older rechargeables of another brand that were giving me blinking lights and I had to hunt the web for the answer. Other than that these are perfect and hold a charge very well. The ones I got were ~85% charged, which meets the claim that they are ready to use. I still topped them off before using them though. You do need to make sure your device is compatible with these batteries though. I saw one guy say they were terrible because they didn't work in his GPS. His GPS wanted voltage over 1.5V, which these aren't going to give him. But for normal devices like XBox controllers, flashlights, TV Remotes, radios, night lights, etc, these are excellent and keep a lot of junk out of the land fill.

Eneloop..... Excellent, unbeatable, unmatcheable batteries. I've tried dozens of different brands rechargeable batteries. All of them died soon, didn't hold enough charge and had a high shelf-discharge, i.e., lose the charge when not in use. I've used only Eneloop in the last few years and I may guarantee that: 1. Their charge last about 50% more than a regular alkaline battery; 2. I never had one that died. Some of my batteries have been charged for several hundreds of times with no loss of effectiveness; 3. They have almost zero shelf-discharge. Once you charge it, it will be good for use for more than one year. They are not cheap ... but when I think how much I've saved and how I didn't produce toxic waste, they become a real bargain. Just make a calculation and you will see that a few recharges pay their price.

A battery charger, a wise investment For those who seek a green achievement The Panasonic eneloop is the one Compact and portable, always on the run Charge batteries with ease, quick and efficient No need to panic, always ready in an instant Rechargeable with lifespan so long Cost-effective and eco-friendly, a perfect throng My opinion is, it's worth the buy For those who aim to save and simplify But take note of some issues reported Be aware and cautious, it's recommended and supported.

Great batteries. Long lasting. We use these in our underwater strobes, and they perform quite well. Although personally I prefer to use the Nitecore D4 smart Charger Nitecore D4 smart Charger 2015 version with LCD display For Li-ion, IMR, LiFePO4 26650 22650 18650 17670 18490 17500 18350 16340 RCR123 14500 10440 Ni-MH And Ni-Cd AA AAA AAAA C Rechargeable Batteries with Ac and 12V DC (Car) power cords, 2 x EdisonBright AA to D type battery spacer/converters to charge my batteries, but the charger that is included with this package does quite well for everyday needs. I have never had a problem with either the batteries or the charger. Note on item description: The Product is Eneloop, it is mis-typed "envelop" in the item description. Also it would be helpful to state exactly what comes in the package. ie: 10 AA and 4 AAA batteries with 1 charger included.

After days if not weeks of researching, I finally decided on buying these Panasonic Eneloops. If you're looking for a pair of AA's for something like a 360 controller, wireless mouse, or even Steam controller, these are exactly what you're looking for. Depending on the device however, they can fit extremely snug. You may have issue getting these out of a controller due to the size of them and might have to pry them out using some leverage. The 4 AAA's that come with this bundle are what make it so great. Although the usage of them is more rare than AA's, with the pair you no longer have to worry about not having some on hand. Some smaller remote controls or older cameras that need them will work perfectly with these. Note that due to the design of NiMH batteries things may not appear to be charged fully 100%, but that's only because they're designed to monitor at an alkaline's 1.5v level. This may cause issue if you rely on the battery level monitor to replace things, but if you always have an extra pair on hand you won't have to worry. Especially if your main use is something like a game controller which will last much longer than normal alkaline batteries. You literally cannot go wrong with this purchase, and the reviews show it.

I've been using eneloops for years and they never disappoint. Watch out for clones and competitors that make bold claims - at the time of this writing, these are made in Japan and the quality shows. The charger in this kit is excellent - compact and feather-light, perfect for travelling and when stored out of the way. Batteries just go on and on, I used them mostly in flashlights, laser pointers, and game controllers. They hold a charge for a long time both when they're in long term storage or when actively used.

Compré este articulo en 2015 y tres años después siguen funcionando como el primer día; jamás he notado que su capacidad de carga se vea reducida. Principalmente las utilizo para controles de TV/estereo/barra de sonido, Videojuegos (Xbox One y GameBoy) y alguna que otra vez para lámparas de mano, radios de pilas y hasta para el ''boiler'' de paso (Para usarlas con mi calentador tuve que comprar el adaptador de ''AA'' a tamaño ''D''), creo que es en éste último en donde me han quedado a ''deber'', pues al parecer las baterías de tonos azules no proporcionan la suficiente energía para generar la chispa que enciende el calentador (sólo cuando tienen carga completa, después de aprox. 15 usos aunque aún tenga mucha carga ya no es suficiente para la chispa) cosa que no sucede con las Eneloop blancas. Por todo lo demás son una excelente inversión.

worth the purchase. haven't had to buy batteries in years.

Recibí como ya es costumbre en amazon el producto antes de tiempo y en buenas condiciones, el cargador con las baterias se me hizo una excelente oferta ya que por ese precio solo puedes comprar las baterias, que ademas he tenido ya tiempo usando esa marca y esta parecen ofrecer mejores prestaciones ya que resisten hasta 2100 cargas, el cargador luce bien ya hize mi primer carga y todo funciona de maravilla, necesito probarlo mas con diferentes marcas de baterias pero por lo pronto estoy muy satisfecho con mi compra, recomiendo el producto al 100% y Amazon una vez mas que buena tienda online. Gracias

Great set of rechargeable batteries. A little expensive, but have been using them for years and they are still going strong!
