This special price is for a bundle of TWO four-pack of Panasonic Pro (Sanyo XX) Eneloop AA 2550 mAh batteries.

Panasonic's next-generation nickel metal hydride battery eneloop.

Batteries have a property to release the stored energy in small amounts (this phenomenon is called self-discharge). This property is particularly noticeable in rechargeable batteries such as Nickel Metal Hydride Batteries etc. as compared to dry cell batteries, hence disabling rechargeable batteries from becoming batteries that customers can use immediately after purchase. For this reason, rechargeable batteries couldn't be used unless charged after purchase and so lagged behind dry cells in convenience. This new products main property is that it has introduced great improvements in self-discharge properties (residual ratio after one year of non use is 75%, in temperature conditions of 20 degree Celsius according to SANYO research). Through this breakthrough development, SANYO has realized a rechargeable battery that can challenge dry cell batteries in user-friendliness through features such as making possible use immediately after purchase or once charged, its ability to be used anytime.


How was the self-discharge reduced?

Modern Ni-MH batteries consist of two metal stripes ( anode and cathode ), which are separated by a non-conductive porous plastic foil ( separator ). These three stripes are laid on top of each other and are winded to a coil. This coil is put in a metal can and immersed with a liquid ( electrolyte ). Then the metal can is closed with a cap. The self discharge of Ni-MH batteries is caused by three main reasons:

* the chemical decomposition of the cathode,
* the natural disaggregation of the anode,
* Impurities of the anode.


Now, how could the self-discharge in the eneloop been reduced? The chemical decomposition of the cathode has been reduced substantially by the use of a new superlattice alloy.

As an additional benefit the superlattice alloy increases the electrical capacity of the battery and reduces the internal resistance, which allows higher discharge currents.

Another advantage of the reduced decomposition of this alloy is the fact, that less Cobalt is needed to stabilize the alloy.

The anode has been strengthened by another new material, which reduces the natural disaggregation.

Additionally the separator and the used electrolyte have been optimised for low self discharge of the eneloop.

Low self-discharge - the key-advantage



What makes the eneloop unique?

The key-advantage of the eneloop compared to usual rechargeable batteries is its extremely low self-discharge.


Retains Capacity... Even After 12 Months


Once charged, eneloop retains its charged capacity even after 6 or 12 months of storage
(80% of Charged Capacity retained after 6 months, 75% Capacity after 12 months).

eneloop batteries are pre charged and is ready for immediate use after purchase, straight from the pack. Just like Primary Batteries. There is no need to charge-before-use.


For a rechargeable battery this is a revolutionary advantage.

No more worries about the state of charge of your battery.

Just, charge them and keep them.

Even after months you will still have an almost fully charged battery.


In contrast to a disposable battery the eneloop can be charged 1000 times. This saves the environment and your purse.

Thus one eneloop saves the waste of 999 disposable batteries.

SANYO has been a market leader in nickel metal hydride batteries for the consumer market. The synergy of the following proprietary technologies of SANYO in developing high capacity products has made the successful development of eneloop possible:

1. high-performance negative electrode superlattice alloy
2. make-up of battery material and battery plates
3. maintain quality despite being out of use for a long time

These are a few of the technologies that have helped contain self-discharge during the period for which the battery is not in use. Furthermore, it also inhibits voltage reduction even after a long period of being out of use.

eneloop - the only battery you will ever need



One battery for all applications


Does this sound familiar to you?

You stand in the electronic shop and you only came there

to purchase a pack of batteries.

But the rack in front of you is full of batteries.

Batteries for this application and batteries for that application,

cheap batteries, expensive ones, red, yellow, blue and green

batteries, disposable batteries, rechargeable batteries,

AA, AAA, C and D sizes - You are confused.

There is an end to this confusion.


eneloop is the right battery for all your applications.

It replaces disposable batteries in

Remote controls,
Cameras
Clocks and alarm-clocks
Electric torches,
Radios,
LCD-TVs
Toothbrushes
Shavers
Flashlights
Toys,
MP3-Players
Electronic games
Computer-keyboards und mice.

No more need for special batteries

Several manufacturers offer special disposable batteries for certain applications like cameras or audio. They claim, that only these special batteries have enough power to run these applications.

No more need for these expensive special batteries. eneloop is powerful enough to run all these applications without problem and even better than any of the special disposable batteries.

Expensive batteries or cheap batteries?

Sure, also in batteries performance and quality is not for free.

But please compare the price of eneloop with the price of high quality disposable batteries. - And remember, that you can use one eneloop 500  times. The decision should be easy.


eneloop-more performance for your digicam








With eneloop you can make substantially more shots with your digital camera than with any other disposable battery.

The main advantages of Ni-MH rechargeable batteries exist also in the eneloop:

- appr. 4 time more shots than with alkaline batteries

- high performance even at low temperatures
down to 10 C during your winter vacation

- rechargeable and therefore cheaper on the long run.











Additional advantages of eneloop
In comparison to other, conventional Ni-MH rechargeable batteries eneloop offers several additional advantages
for the foto-amateur:

- eneloop can be stored in charged state - in the camera or separate as backup replacement.
- The state of charge can be predicted very well and can be planned.
- The time you need for charging the battery is not relevant any more, because the eneloop can be charged long before the actual application and kept charged.
- expensive quick-chargers are no longer necessary.
- never again forget to charge before you start your trip.


Charging made easy



Charge your battery when you want

With normal rechargeable batteries it made sense to charge them just before you wanted to use them. Too much risk otherwise, that the battery did not provide full power, when needed. Therefore there was a checkpoint on every vacation checklist: Charge batteries.

The the endless time, till the batteries are finally charged.

Even with the most advanced and most expensive chargers it still takes 15 minutes. This can be very long 15 minutes, if the taxi is waiting at the door.

Now you can forget all this. Charge the eneloop, whenever you have time for it and store them. The extremely low self discharge of eneloop saves you from all the charging stress.

When you use eneloop in your household equipment, spend some extra money and purchase a set of spare eneloops. Keep these spare eneloops stored in a charged state and you will allways have fresh batteries at hand whenever you need them.


Chargers

Basically eneloop is a modern Ni-MH battery, which can be charged like any other Ni-MH battery.

Therefore eneloop can be charged also with other, modern chargers, which are suitable to charge Ni-MH batteries.

Also SANYO cannot be held responsible for any damage to eneloop batteries caused by unsuitable chargers
