eneloop 2100 cycle rechargeable Ni-MH batteries maintain 70% of their charge for up to 5 years¹ when not in use.

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.

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.

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° F⁴

eneloop offers a lower cost of ownership saving, as much as $1000 per cell vs. regular Alkaline batteries. Each eneloop cell can cost less than 4 cents per recharge.

Regular disposable AA and AAA batteries are considered Primary Cells, more 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.

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.

The chemical makeup of Ni-MH batteries allows the cell to 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. They have increased "low self-discharge" performance on Ni-MH rechargeable batteries which allows eneloop cells to store power for longer periods of time.

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 literally 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.

eneloop's "signature features" include ready to use rechargeable power with the ability to hold 70% of their charge for up to 5 years (when not in use)1, can be recharged up to 2100 times2, they have no "memory effect" and outstanding performance even in extremely low temperatures (down to -4° F)4.

Americans deposit up to 6 billion disposable batteries into landfills each year! eneloop batteries can be recharged up to 2100 times, which means that the purchase and use of a single eneloop cell can keep hundreds of batteries from entering landfills. They can also be recycled free of charge at any of the 34,000+ www.Call2Recycle.org recycling centers near you.
