Eneloop Panasonic K-KJ55MBS66A Power Pack; 6AA, 6AAA, and Advanced Battery 3 Hour Quick Charger

I am a millennial. I grew up with the Sega Game Gear which was a great entertainment device, but its LCD color screen was also adept at sucking the life out of 6 AA batteries. Back then I had to use rechargeable batteries and the experience so traumatized me that as a teen and young adult, as USB became ubiquitous I decided to only use gadgets that would operate (and recharge) through USB ports. As an adult, I have found that there are a handful of devices that I use that require batteries: - Cheap little lights diodes in the bathroom, or foyer for accents; - Wireless headphones to watch the TV; - Xbox controller. Eventually I realized I was using batteries regularly, and I even though I had them recycled, I am not sure exactly what the recycling process entails (and whether it is successful/legitimate...). The first couple chargers I tried were terrible. After reading many reviews I picked a LaCross model: https://www.amazon.com/gp/product/B004J6DLD4/ I thought it seemed like it had everything I needed. When I got it, it turned out it didn't work properly because the prongs didn't make good contact with the batteries. It would detect some of my batteries as "not present" for this reason. In addition, even though I have post-graduate degree, I can't make heads or tails of the numbers—and in truth I don't care about them at all. I returned that charger. This is why the Panasonic eneloop system is perfect, it swaps those inane numbers for something simple, colors: - red means less than 20% charged; - orange means 20-80% charged; - green means over 80% charged. Here are the pros: - The color-coded read-out is simple to understand, and doesn't overload you with information. - Can charge any number/combination of AA and AAA batteries (even odd number of batteries) - Can charge batteries with different charge levels at the same time. - Automatically stops charging batteries when they are full. I can't find any cons. I picked up a 4-pack of AA batteries in addition to those provided with this charger. I haven't bought any batteries since, and my initial purchase was three months ago.

Panasonic charger is easy to use, and with the advent of NiMH batteries, there's no need for complicated chargers with settings for draining or reconditioning batteries. This charger simply works, at least for high-quality batteries in good condition. Just insert the batteries and the charger does the rest, then stops charging each individual battery when that battery's charge is complete. No concern about leaving the charger unattended, even overnight or long-term. Unlike some chargers on the market, this Panasonic charger can charge single batteries at a time (rather than requiring batteries to be charged in pairs). It also charges slower than the rapid chargers peddled on Amazon, and that's a good thing, as slower charging incrases battery life. The only knock against this Panasonic charger is the fact that the lights aren't quite as intuitive as some other chargers, but it only takes Siri a second to pull up the guide/explanation of the lights. If you need a simply, effective, safe charger for AA and AAA batteries, I highly recommend this Panasonic charger or any of the Panasonic BQ chargers. The Panasonic eneloop batteries are simply the best and are worth the slight premium price. I've tried the Amazon Basic, EBL, and Energizer rechargeable, but none of them work as well as the eneloops.

Excellent batteries you Can Not find a better rechargeable batteries than these on the market, they have remarkable rechargeable rate,longevity,quality, and energy storage (mAh) I have been using this type of battery from this manufacturer for years now and they are hands down the best battery i have ever owned due to them being meticulously manufactured in Japan and not cheaply made in China like the competition. Spend a few more cents per battery and save hundreds of dollars in the foreseeable future, (Do the math) you won’t be disappointed by choosing this excellent product. As for the charger it’s made in China so only time will tell if it will last (so far the charger is still functioning but it’s made in China so ya…).

Lots of kids toys. We have a couple of these so we never run out of batteries.

These Enloop batteries are really good: capacity as good or better than alkaline single-use, AND THEY DON'T LEAK! They claim to hold charge for 10 years--I haven't had them that long, but I have had others unused for two years, and they were great. The battery charger is really good also, except I much prefer the old lights below the batteries to show charging and full (the reason I took off one star). A light that changes from green to red doesn't work for the 8% of males who are red-green color blind.

This recharges batteries with lightening speed. Very happy with this purchase.

Very good charger. And the batteries are awesome. If you are looking for a charger and rechargeable batteries - look no more, you've found them.

Siempre tuve problemas con otras baterías recargables que al poco tiempo dejaban de mantener la carga o directamente dejaban de carga. Investigue un buen rato sobre calidades y demás, y estas tienen un excelente rendimiento, sin mencionar que tienen incluido uno de los mejores cargadores que hay para baterías, ya que puede recargar baterías de manera individual, te muestra el porcentaje del proceso de carga y se apaga automaticamente cuando ha terminado el proceso de carga. Una chulada de cargador y de bateria.

Not as good as I thought / what other people suggested. I don't use it for high voltage applications, just to be clear. All I want is its advertised longevity (could'n tell it's only a year and a half) and most importantly the low self discharge property. Maybe I'm wrong about the definition but these betteries constantly(once several weeks) need to be recharged in case I need them . Maybe I was having too much expectation of "maintaining state of charge on shelf up to several years" but yeah it's ok bettery just like its made in china counterpart cause you get what you paid for, correct? As for the charger, it's ok "warming up" during operation I don't worry about it causing a fire but it did heat up the bettery pretty fast and badly (how hot? "take it out and put it back the charger refuse to charge it" hot), especially when there're less than 4 betteries' in it (which is almost all the time in my case). meh made in japan

Having 6 AA and AAA is a good start when trying to only use electric batteries. The quality of the product is great. Panasonic's eneloop really does make the best rechargeables. The individual indicators are the best part, letting you know the state of each battery. I recommend this product to everybody.
