eneloop Super Power Pack Featuring 2100 Cycle Ni-MH Pre-Charged Rechargeable Batteries

eneloop Ni-MH “Low Self Discharge” batteries utilize Panasonic’s advanced rechargeable battery technology allowing them to be recharged up to 2100 times**. eneloop battery cells deliver consistent power performance, maintain 70% of their charge for up to 5 years*, come pre-charged by solar power (at the factory)*** and are ready to use out of the package. These eneloop cells also have increased storage life and extreme temperature performance down to -4 degrees Fahrenheit. ****

eneloop. ..The Birth of a New Technology

Since 1931 Panasonic has been a leading manufacturer of battery technology. In 2005, eneloop was launched as a new type of rechargeable battery that would change the way people live, work and play. This rechargeable battery was created with a very simple idea in mind; provide a common energy source that can be reused over and over again. This “looping energy” became eneloop. Today, eneloop battery cells are recognized by millions of consumers worldwide as the industry’s premier rechargeable battery.

Long Storage Life

eneloop 2100 cycle rechargeable Ni-MH batteries maintain 70% of their charge for up to 5 years* when not in use.

What Makes eneloop so Incredible

eneloop batteries utilize a highly-durable super lattice alloy which prolongs the life of this important material. Improvements to this super-lattice alloy have increased hydrogen stability resulting in reduced self-discharge and long lasting, stable voltage output.

Solar Panels at the Factory
Clean Energy from the Factory to Your Device

eneloop’s unique "Clean Energy Loop" initiative is a reality. All eneloop 2100 cycle and eneloop pro batteries are pre-charged at the factory in Japan using power generated from solar energy. This process is certified twice a year by the Green Energy Certification Center.

Improved Conductive Surface Layer

Improvements to the conductive surface layer of the active (positive) electrode material (made primarily from nickel-metal hydride) produce greater conductivity and durability. By limiting the degradation of the conductive layer, it has been possible to reduce performance degradation during repeated use and thus increase the number of times that eneloop batteries can be recharged – all without increasing the amount of negative electrode alloy used and enabling the new eneloop cells to be recharged up to 2100 times.

Consistently Stable Power

The initial voltage level of a battery provides no indication of how long the battery will last or how much power it can deliver. Alkaline battery cells rapidly drop below 1.5V soon after they are put into use and the voltage continues to steadily decline over time. Since alkaline cells are non-rechargeable, they must be discarded and then replaced. eneloop batteries deliver best-in-class Ni-MH high capacity power and “rechargeability” combination up to 2100 times. Devices including cameras flash units and wireless game controllers can easily draw more than 1000mA of current; rapidly depleting alkaline batteries power. eneloop batteries maintain a consistently high voltage level keeping your devices operating for a long period of time.

Works in Extreme Temperatures Down to -4 Degrees Fahrenheit
Performance Down to -4 Degrees Fahrenheit

Keep your tactical flashlights, walkie-talkie radios, battery powered lanterns, cameras and other devices powered in the winter. eneloop 2100 cycle and eneloop pro batteries deliver exceptional performance at extreme low temperatures, down to –4°F. ****

Style Name: Charger Pack
I purchased the Panasonic K-KJ17MCA4BA package, which includes the BQ-CC17 "Advanced Individual Cell Charger", and four 4th-gen eneloop AA cells that are rated '2100 cycles'. For reason that will become apparent later, this review is focused on the charger.

I have been using eneloop batteries since the first-gen was introduced to the US market back in beginning of 2007. Over the past 7.5 years, I have tested 2nd-gen (1500 cycles), 3rd-gen (1800 cycles) and lately the 4th-gen (2100 cycles) eneloop cells. I have no complaints about the quality of eneloop cells. But I'm always unsatisfied with the charger bundled with most eneloop packages.
- The MQN05 (bundled with initial eneloop packages back in early 2007) can recharge individual cells. But it is only rated for 120V AC input. There is just one indicator light, which goes off when all cells are fully charged.
- The MQN06 (bundled with most eneloop cells sold between late 2007 and beginning of 2014) can only charge in pairs. I call it 'semi-smart' at best.
- The MQR06 (introduced to US market in 2012) is faster, handles individual cells and accepts 100-240V AC input. But it is a lot more expensive.

My review is for the Panasonic K-KJ17MCA4BA Advanced Individual Battery Charger + 4 AA Batteries.

I purchased this product as a better alternative to the Sony CycleEnergy charger I purchased last Christmas at a B&M store in Germany for €29.99 (about $37 USD). The biggest disadvantage I had with the Sony CycleEnergy charger is that it required me to always charge batteries in pairs, which ended up becoming problematic after noticing that the batteries don't always charge equally. I would charge the batteries until the LED light would notify me that they are ready to use, yet after inserting them into my high-power devices the batteries would already read one to two bars lower instead of indicating all the bars for a full charge. At the time I also only owned two rechargable AAA batteries, one which was used for my wireless laptop mouse and the other for a Bluetooth stereo remote. This also turned out to be a problem since the wireless mouse would drain the battery very quickly whereas the battery in the remote would barely lose its charge, which in turn would force me to charge a near dead battery with an almost full battery.

It was at this point that I started looking into a better alternative for charging my rechargable batteries, and after a bit of research I came across the Panasonic BQ-CC17 "Advanced Individual Battery Charger". The reason I chose to go with this specific brand and charger was because it has excellent ratings, the great price, and most importantly allowed for individual cell charging.

I cannot express how pleased I am with this product, and I highly recommend this product without any hesitation to anyone in need of an excellent battery charger!

The batteries that come with this great charger states a minimum of 1900mA. After they are fully charged I took 2 out and install it on a cheap Philips electric shaver, turn it on, started a stopwatch and watched a 2hr movie. When the movie ending credits started rolling, the shaver was still going on, strong.

Started another movie. By the time shaver stopped running, time clocked is 3 hrs 27mins.

Also confirmed that it can charge a single battery anywhere on the 4 available slots. Put 2 in positions 1,3 or 2,4 still works. Screw those models that allow charging only in pairs - the designers think with the head w/o the brain.

The green leds are "embedded" inside and only light up in green when charging. When charging is completed they really did turn off. So overnight charging is cool, no worries about overcharging and slow-kill the expensive batteries.

No charging cable. At the rear you flip out a 2-pin plug that connects straight to the wall socket.(see my pix)

I got another set of four AA's and a pack of eight AAA's. This is a must have kit when the gizmos you have run on batteries, esp radio controlled toys since they eat batteries for breakfast. I don't have radio controlled toys, though..

I am glad some people with knowledge have reviewed this. I ordered the full kit on their say so. I am very pleased. I have ordered a second full kit. I did so because I really like the storage case and thought it might be nice to have a second charger and the full deal twice turned out to be cheaper than adding extra batteries.

The liner in the storage case could be a bit thicker. I hope it lasts. Probably as it will not be a heavy use item. Longevity is something I need to take on faith for now. I won't know for years if these last longer than the rechargeable I was using. I can tell you the charger does seem to monitor the batteries individually as I fried one of the batteries when my electric mouse trap shorted out and moved around in the charger that battery did nothing but blink the indicator light. Just that one battery.

The batteries do seem a fraction of a hair shorter than the standard brand batteries you get at the big box stores and groceries. I needed to pry out a clip or two to use them in everything... Not a big deal.

I am very pleased. The batteries in my TV remote only need recharging once a year. If these can actually be recharged 2100 times these should last me till the year 4114. They may not last as long in the solar yard light? But time will tell.
