Panasonic K-KJ17MCA4BA Individual Battery Charger Pack w/4 AA Eneloop NiMH Rechargeable Batteries

I bought this item, the Panasonic Eneloop kit to stop wasting money on disposable batteries for my Xbox controllers. After about a months of heavy use, I am completely thrilled with the performance. The BQ-CC17 charger lets you charge one, two, three, or four batteries at a time. This is huge if you have devices that use an odd number of batteries. The low self-discharge claim is completely true. I can attest to that, because I really have put some hours on those batteries. Also, the battery charge really last for quite a while. Unlike regular alkaline batteries that eventually leak acid and ruin expensive electronics, these are incredibly safe and well-made. The Charger is an overnight charger, not a rapid one: It takes about 7 hours to fully juice up four completely dead AAs. If you need a 1-to-2-hour quick charge, look for the premium Panasonic CC55 charger instead. Personally, I prefer the slower charge because it generates zero heat and extends the overall 2,100-cycle lifespan of the batteries. Bottom Line: This product pays for itself within the first few months. The batteries arrive pre-charged and ready to go right out of the box. Do your wallet and the environment a favor and just buy them!

Rechargeable batteries are my favorite thing. I have a daughter and kid's toys are forever needing this or that battery. Eneloops have great longevity, and the ability to slot them into different sizes is so helpful. I wish they weren't so expensive, but, they're definitely worth it.

Came pre charged just like the description said. I use them in a water flosser and they provide long-lasting power. I did a small bit of research before I bought these and this brand continually came up as the best bang for your buck. I'm going to be ordering the AAA size as well. For my TV remotes. I'm very happy with them and expect them to last a good long while.

Highly recommend these for anyone who uses devices that require batteries, such as an xbox controller. With everyday use of a couple hours, these batteries last about 14 days. Recharging is easy and stops recharging when they are recharged. Paid $18 for this 4 pack and charger. A large battery pack of AAs, i think 24, at sams club was similar in price but in the month I've had these batteries I would have burned through at least 8 of those batteries.

Good quality. Reasonable price. Easy to use. This model can charge one lone battery. The older version of this charger required batteries to be charged in pairs. This model can even charge both AA and AAA batteries at the same time. I had this shipped for free to the local Walmart near my home. It shipped quickly, and pickup was convenient.

Received only a few days ago but I would doubt as to why Panasonic rechargeable batteries are renowned and miles ahead of other companies within the domain of rechargeable batteries. Their products may be more expensive but it well justified as the quality and longevity of their batteries worth the investment. Time will ultimately either prove to fruition my statements or -😵

I was looking for something for my Xbox controllers and these last me about 15 hours of gameplay on a charge and only take like 3-4 hours to charge back up. So much nicer than the one time use batteries and feels like it'll end up being cheaper in the long run! They are supposed to last about a decade too so that's excellent

Right product at right price.

the batteries died quickly and the charger doesnt work. the charger says the batteries are full but theyre not.

Very disappointed in these enloop rechargeable batteries. They will not hold a charge at all and this is straight out of the package. I purchased these for a smoke detector and a little weather station. They die without lasting 24 hours. Do not waste your money like I did.
