Panasonic AAA 800mAh eneloop Rechargable Batteries White pack 4pcs

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.

eneloop has two "new" authentic styles of packaging:
1. The new eneloop 2100 cycle batteries are packaged in a blue/green cardboard blister pack (shown below).
2. The new eneloop pro in black and silver (shown below).
3. eneloop 1800 and 1500 cycle batteries which were packaged in a blue/green cardboard blister design with an earth image screened on the package (are former packaging 2nd and 3rd generation products).
4. eneloop 1000 cycle batteries which were packaged in a blue and orange cardboard blister (1st generation product).
5. eneloop XX batteries are packaged in a black cardboard blister package (1st generation product).
Products sold in plastic bags or flexible foil style packages are not authorized for sale in the U.S. and may not contain authentic eneloop batteries.
