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.

Extreme Power

eneloop pro, High Capacity Ni-MH rechargeable batteries feature added mAh power, making them the perfect choice for DSLR flash units, game controllers and other devices that require additional power. While eneloop pro batteries were designed to provide more power for high drain devices they will also perform well in conventional devices that require AA or AAA cells.

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**.

Why are Ni-MH Batteries 1.2V?

Ni-MH rechargeable batteries have two electrodes inside the cell: Nickel Hydroxide and Hydrogen absorbing alloy. Battery chemistry of a Ni-MH rechargeable battery generates 1.2V. While alkaline batteries experience rapid drops in voltage Ni-MH rechargeable batteries maintain the same voltage throughout most of the entire charge.

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. ****

Amazing performance
December 3, 2012
Avishai Avivi (Los Gatos, CA USA)

I was doing a photo-shoot of a wedding reception. While originally planning to only be the backup shooter for an hour or so, I had to go for 4 hours. Both my Nikon SB-910 flash and the SS-SD9 battery pack were loaded with the Eneloop Double X AA batteries. I shot over 700 images, and the flash cycled extremely fast, never letting me down. While I was exhausted, the flash was still ready to go! Excellent batteries and awesome performance! Highly recommended.

Best for the Money for Gaming, Disaster Preps and General Use
I'm not a tech weenie. I don't want to have to study in order to buy the best product for my needs. And when I find the "right" thing I am sure to share my opinion so other non-tech-weenies can do the same. Here is my decidedly non-technical review.

My battery needs are varied and extensive. Aside from my beloved X-Box 360 Kinect (oh yes, middle aged women also love Mass Effect series), I've also got remote controls all over the house, mobile entertainment, dog toys, holiday decorations (you know, the creepy santa that moves), portable medical equipment for my mom who lives with me, security lights in the hallways, in house remote cameras...well, a LOT of battery needs. I also have my disaster preparations because I live in a zone known for Hurricanes AND Nor'easters. So much fun.

I was spending a fortune on batteries so I thought I'd try rechargables and I got the energizer recharging kind from the regular department store. They did okay, but I clearly had to recharge them more often and they weren't nearly as good as a set of fresh tossable kind. A friend noted my drawer full of batteries one day and told me that I should give this set a try.

At only $40, it was a no brainer to give it a try and I really can't believe the difference between this system and the energizer one I bought previously. Night and day.

First off, the batteries came pre-charged and testing showed between 93 and 97% charge remaining on every single one. That's pretty good considering it sat somewhere in an Amazon warehouse before I got it. And while I do use an Xbox controller recharge station, I'd rather not wait when I do get time to play something so I usually grab another controller that isn't rechargable and I used these first in that. Turns out, my controller lasted longer with these than the one that goes with the Xbox recharger...that's pretty darn good.

I've had batteries in things for over a month now and nothing has run out (save the Xbox controller), including the safety light in the upstairs hallway that goes on and off every time a person enters the hallway...a lot of use, in other words. The case itself is super handy and eliminates the huge mess in my battery drawer.

I'm also very comfortable with these due to their ability to hold a charge. Each year I have to clean out batteries for rotation in my hurricane/storm kit and it is such a waste. With these retaining their charge...and the additional ones I bought to flesh out the kit with more batteries...I can stop that practice and know I'll have batteries ready to go. I'll update if needed. Really great buy that is highly recommended.
