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

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.

Great set of the best rechargeable batteries I know that exist. I use the black and white Eneloop batteries for more than a decade and they are durable, long lasting and powerful. The black ones are purposed for high power and fast recovery (e.g. flashes). The white ones keep charge longer - for all others uses, like clocks, remotes etc.This specific set is nice. Comes with comfortable case, AA and AAA, along with adaptors for C and D battery types. Charger is good. Allows you to charge 1 to 4 batteries from mixed sizes, each one is handled separately.

I bought these to replace non rechargeable batteries for my rideshare business, I have lights on the side of my car that needed 6 AA's. Non rechargeable lasted about a week for my needs and the price was adding up.These rechargeable beautifully, they had no issue in the car heat during the day. If you eat through batteries bite the high pice up front, it will save you $ in a short time.The C &D adapters are a wonderful bonus but they don't have a long run time at a high out put but you have alot of AA's to switch out through the day. And when they are drained just rechargeable them instead of buying more disposables.All around these work well ,I use them for several applications to suit my needs and no more cost. Just recharge!Buy these if you run through disposables. You will not regret it!

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.

I purchased this set after my Steam controller started chowing through batteries faster than usual, so my gaming habit was becoming unnecessarily expensive! I opted for the set with multiple sizes of battery to replace the power source with something rechargeable for other household devices while I was at it. I have now been using them for a couple of months and have charged them many times.PROS: These batteries work as expected, seem to charge quickly and hold a charge, and last as long if not somewhat longer than traditional batteries.CONS: The charger is a wall bug which I find horribly inconvenient, they do not die slowly as with regular batteries (where you can pop them in and out the controller to get that extra 30 sec. of life out of them... these die fully and without warning, which is unfortunate while gaming), they still only last a couple of days in a controller that sees a couple hours' use in the evenings before needing to be recharged.Overall, these are worth the initial investment if for no other reason than to reduce the negative environmental impact of disposable batteries. They will save you money in the long run, and are a simple, easy replacement to the batteries you normally use. Unlike other reviewers, I did not find any issues with overheating or anything like that. I would recommend these.

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!

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

This is my second set I've purchased. I love these batteries and buy them often to keep a good selection and size caps on hand. They last a long time on one charge and recharge thousand's of times. Highly recommend them. Recommended by Jeffrey Yago who wrote "Lights on" book, too. Definite value for your money.
