Eneloop Panasonic K-KJ17MC124A Super Power Pack 12AA, 4AAA, 2 C Adapters, 2 D Adapters, Advanced Individual Battery Charger and Plastic Storage

These batteries have been a life saver for me. I go through plenty of AA batteries even in this age. Especially for my Xbox controller. While I don't know when they will die in the controller, they still last plenty long when playing constantly. They hold they're charge too. I can come back a month later of not touching devices that use them and they still last just about the same amount of time as I expect after using them for a bit.Just make sure to rotate the batteries and charge the overnight as the default charger takes about 7 or more hours to finish. You can buy faster chargers but that is an additional charge for your wallet.

Work great! Fast charging speed. Battery life lasts pretty long

Got this set mostly for use with my Xbox controller. Way better than the rechargeable battery pack accessory. I always have some batteries charged and ready to go, and they last such a long time. Probably could have gotten away with a smaller pack but these will surely last for years and years so I'm not too upset.

These eneloop batteries by Panasonic are by far the best batteries around. Read any review on another battery and they compare them to these, this is the bar to rate others.They are more expensive than others but for good reason. These batteries come fully charged by solar power which is awesome. They last a long time, easy to recharge. And will last longer than me.This set has a nice storage case, and charger. It has a variety of of sizes. The C and D are empty shells, that you put a AA into the shell. The charge only fits AA and AAA, you take the AA out of the C and D shells to recharge and swap it out with a fully charged one.These are not my first set of these batteries. I've slowly been changing everything we own to these.

Kinda misleading, their math is not mathing, straight out of the box these "fully charged" batteries are at about 35% so they've either been sitting for 30 years or the 10 year claim is bogus.

Compré este pack porque quería aumentar la cantidad de baterías recargables y poder acceder a las tipo C y D con los adaptadores que vienen en el paquete, llegó en en el tiempo acordado, completo y en buen estado, el rendimiento cumple las expectativas, de lo que más me gusta es el cargador, aunque hay cargadores de otras marcas que ofrecen carga en menor tiempo, de este me gusta que muestra la evolución de la carga de cada batería. Es una excelente compra en especial, si cómo yo han cambiado prácticamente todas la baterías por recargables, eso ayuda al medio ambiente, a la economia y en caso de que necesiten baterías no puedan salir a comprarlas por la hora o el lugar donde viven, solo las ponen a cargar y listo y como recomendación, no esperen a que todas las baterías se descarguen, en caso de un corte de energía nos les van a servir si están todas descargadas y no tiene energía para reponer la carga.

I recently purchased the Panasonic eneloop super power pack rechargeable batteries, and I must say, they have far exceeded my expectations. As a dedicated gamer, the performance of these batteries in my Xbox controller has been nothing short of impressive. The charge seems to last twice as long as my previous rechargeable batteries, allowing for extended gaming sessions without interruption.One of the standout features for me is the carrying/organizer case included with the batteries. As someone who tends to misplace things easily, having a dedicated case to keep track of the batteries has been a game-changer. No more searching through drawers or under couch cushions to find them; they're always neatly stored and ready to use.Additionally, the build quality of the batteries and the case is top-notch. The batteries feel solid and durable, and the case is well-designed for easy access and storage. I appreciate the attention to detail that Panasonic has put into both the batteries and the accompanying accessories.Overall, I couldn't be happier with my purchase of the Panasonic eneloop rechargeable batteries. They offer exceptional performance, convenient organization, and excellent build quality. If you're looking for reliable rechargeable batteries for your electronic devices, look no further than these. Highly recommended!

I heard about the extensive testing that Steven Harris did on these batteries, and have listened to many of his videos on emergency power, and these are the only brand that he personally recommends after testing how many time he could recharge these Enloop batteries. I bought the set on a Black Friday lightning deal for about a 35% discount, but it's worth the full price, every cent. Our kids got an Xbox One for Christmas with Minecraft, and of course they wanted me to play with them over their 2+ week break. I had already charged up all the batteries, AA and AAA, and bought another pack of Enloops AA's on sale figuring I had enough for multiple toys plus 3 wireless Xbox controllers...Wrong! I now have more than enough for ALL their new toys and more (I've got about a dozen spare AAs ready to roll at any time, in a holder... but, I do need a few more AAAs for TV remotes as the cheapie batteries wear out.)What impressed me the most though, is the fact that it's January 8th, and today, after maybe 2 weeks of hardcore Xbox playing with a pair of seemingly inexhaustable 6 year olds, I actually saw the first message that my batteries were getting low in the controller. 2 weeks! That includes controlling a few BluRays (and figuring THAT out wasn't the easiest for an old guy!), and playing I don't know how many hours (MANY!) of Minecraft... I was wondering if I'd ever really need to charge these batteries. I don't write all that many reviews, especially not so detailed, but I came to order another pack of AAAs, so here I am. Thinking maybe I'll be able to pass these batteries down for a generation or two, if they all last that long, and can be recharged 2,100 times! ;-)Fantastic value for the money!
