Sanyo announce the total global shipment of eneloop rechargeable batteries reached 150 million at the end of December, 2010

eneloop rechargeable batteries have received high market appraisal for having the characteristics of both dry cells and rechargeable batteries. The batteries come pre-charged and ready to use like a dry cell, and are economical and environmental as they are able to be recharged for repeated use as well as recyclable at the end of their lifecycle. According to a company survey, the satisfaction level of “eneloop” users is over 90%*1, and numerous companies now bundle “eneloop” batteries with their products. The sales of “eneloop” batteries in more than 60 countries worldwide is steadily growing year by year.

• An extra of 500 charging cycles
• Improved self-dischcharge
• Batteries have vents under the battery film
• Round tips on the positive end
• Slightly larger negative terminal
• Packaging includes the crown and model number HR-3UTGA (Packaging can vary)

What is the difference between the “old” and the “new” improved eneloop?

• An extra of 500 charging cycles – instead of being rechargeable 1000 times, the new eneloop is even rechargeable up to 1500 times.
• Improved self-dischcharge. Even though the self discharge of the old eneloop was already very impressive, you can store the new eneloop for 3 years and still it will retain 75% of its capacity.
• You need a battery, which is reliable even when having cold temperatures? Before eneloop was suitable for temperatures as low as -10°C – now even until -20°C.
• The new eneloop is even more environment-friendly as it is pre-charged with solar energy in Japan.

Rechargeable up to 1500 times.

Incorporating new technologies for material, manufacturing method and structure developed through the knowledge gained since the first release of eneloop the number of times a battery can be recharged has been increased by the factor 1.5 to approximately 1,500 times compared to the conventional models. With the ability to recharge the battery more times, the new “eneloop” is both more economically competitive and enhanced in environmental awareness as it means the amount of overall battery waste will be reduced.

How MAHA reduced the self-discharge of NiMH Batteries.

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.

SANYO’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 product’s main property is that it has introduced great improvements in self-discharge properties (residual ratio after one year of non use is 85%*4, 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.

The ready-to-use AccuLoop 2100 mAh AA NiMH rechargeable battery offers the advantages of both alkaline and NiMH cells without their disadvantages. Similar to NiMH rechargeable batteries, the AccuLoop can be recharged up to 1000 times. But unlike NiMH batteries, they keep most of their capacity over time. AccuLoop batteries outperform even top-notch NiMH batteries with higher initial capacity. While conventional rechargeable batteries lose 20% of their capacity each month, AccuLoop only loses 2% of its capacity each month.
