INCREDIBLY LONG STORAGE LIFE 
SANYO 1500 cycle rechargeable eneloop Ni-MH batteries maintain up to 75% of their charge after three years of storage compared to conventional rechargeable batteries which often have 0% charge after only 2 years of non-use.

2-POSITION USB CHARGER, CHARGE ONCE AND USE YEARS LATER
eneloop batteries offer exceptional shelf life so you can use your rechargeable batteries when and where you need them most. The USB charger is designed for charging two AA or AAA eneloop or other Ni-MH batteries. It can charge an AA rechargeable eneloop battery in 2.3 hours per battery cell, or it can charge an AAA rechargeable eneloop battery in one hour per cell.

KEEPS YOUR DEVICES POWERED IN “EXTREME” COLD WEATHER
Keep your portable players, cameras, flashlights and other devices powered in the winter. eneloop 1500 cycle and XX batteries deliver exceptional performance at extreme low temperatures, down to –4°F.
ENELOOP...CLEAN ENERGY FROM THE FACTORY TO YOUR DEVICE
SANYO’s "Clean Energy Loop" initiative has become a reality. All eneloop 1500 cycle and XX batteries are charged at the factory in Japan using power generated from solar energy.



WHEN IS 1.2V BETTER THAN 1.5? 
eneloop…Consistently High Voltage Level 
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. SANYO’s eneloop batteries deliver best-in-class Ni-MH high capacity power and are rechargeable up to 1500 times. Devices like cameras flash units and wireless game controllers can easily draw more than 1000mA of current; rapidly depleting alkaline batteries. 

eneloop batteries maintain a consistently high voltage level keeping your devices operating for a longer period of time. When you use eneloop Ni-MH rechargeable batteries, you will realize that “1.2V” can indeed be better than “1.5V”.



WHY ARE ALKALINE BATTERIES 1.5V? Regular disposable AA and AAA batteries are considered Primary Cells, and are most widely recognized as conventional “alkaline” batteries. There are two electrodes inside each cell; one is made of Zinc, known as the anode (the negative terminal) and the other is made of Manganese Dioxide, known as the cathode (the positive terminal). The electrodes are surrounded by an alkaline electrolyte, the chemical from which alkaline batteries get their name.

Battery chemistry of an alkaline battery generates 1.5V. As the chemical reaction fades, so does the power of the alkaline battery cell. This is why the voltage from alkaline batteries drops off shortly after the battery is put into use and the power continues to fade over time.


WHY ARE NI-MH RECHARGEABLE BATTERIES 1.2V? 
Ni-MH rechargeable batteries have two electrodes inside the cell: Nickel and Mercury Hydride. Battery chemistry of an 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.

The chemical makeup of Ni-MH batteries eliminates the “memory effect”, which means the cells can be recharged at any time without having to be fully discharged.

eneloop batteries have continued to raise the performance bar in Ni-MH rechargeable technology. eneloop has increased “low self discharge” performance on Ni-MH rechargeable batteries which allows eneloop cells to store power for longer periods of time.

WHAT MAKES ENELOOP THE BEST RECHARGEABLE BATTERY The new SANYO eneloop battery incorporates a highly-durable super-lattice alloy which lessens the deterioration of this important alloy material. This super-lattice alloy increases the electrical capacity of the battery chemistry through lower internal resistance and delivers a long lasting, stable voltage output. 

A new strong, thin outer case has also been added to the eneloop battery design in order to improve the internal cell space efficiency. The new case optimizes the balance of the components and when combined with other improvements have led to an increase in the number of times that eneloop batteries can be recharged.

eneloop = LOWER COST OF OWNERSHIP
Wireless game controllers incorporate power-hungry features such as built-in speakers, gyroscopes and motion sensors. Consider the hidden cost of ownership in operating two wireless game controllers.

Let’s make the following assumptions: 

1. You play video games one hour per day or 365 hours per year, using two remote/wireless controllers.
2. A pair of batteries (either alkaline or eneloop) will provide you with roughly 20 hours of game-playusage time.
3. In the first year, you will need 18.25 pairs of batteries per controller (either new alkaline or recharged eneloops).
4. You will consume 73 alkaline battery cells in one year (for two controllers) compared to only 4 eneloop cells which can be recharged 1500 times ($0.04 per cell).
5. Four AA Alkaline batteries will cost roughly $5.49 MSRP.
6. Four AA eneloop batteries with an AC charger will cost $21.99 MSRP.

Now let’s look at the annual cost of ownership in only the first few years and then extend it out to ten years (at that point, you probably won’t be playing on the same game system). It is quite obvious that eneloop more than pays for itself in just the first year of ownership!

NEW 1500 CYCLE VS. ORIGINAL 1000 CYCLE ENELOOP
The new 1500 cycle eneloop delivers four important new features

1. 500 extra charging cycles - The new eneloop is rechargeable up to 1500 times
2. 33% improved low self-discharge - The new 1500 cycle battery maintains 75% of its charge for up to 3 years when not in use. The original version maintained 75% of its charge for up to 2 years when not in use.
3. Improved low temperature performance - The new 1500 cycle battery can be used in environments down to -4 degrees F. The original eneloop can be used in temperatures as low as 14 degrees F.
4. The new eneloop 1500 cycle battery is even more environment-friendly – each battery cell is pre-charged using solar energy when it leaves the factory in Japan.

Genuine SANYO eneloop Batteries
SANYO has three authentic “styles” of packaging: 1. The 1500 cycle batteries which are in a blue/green cardboard blister design with a earth image screened on the package. 2. The 1000 cycle batteries are in a blue and orange cardboard blister pack. 3. The eneloop XX batteries are in a black cardboard blister package. Products sold in plastic bags or flexible foil style packages are not authorized for sale by SANYO in the U.S. and may not contain authentic SANYO batteries.

How to tell the difference between the “new 1500" and the “original 1000” eneloop batteries
It is easy to distinguish between the 1500 and 1000 cycle eneloop batteries. The 1500 battery has a gray top (in the Green/Blue package pictured) and the 1000 (in the Blue/Orange package pictured) has a white top.
