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.
A strong, thin outer casing also provides improved internal cell space efficiency of the eneloop battery design. This battery shell optimizes the balance of the components and when combined with the improved alloy material and conductive surface layer of the positive electrode active material enables the new eneloop cells to be recharged up to 2100 times.
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.
*eneloop Recharge Cost Assumptions and Calculations
0.144 Kilowatts @ 8 hours
4 eneloop AA --- 2100 recharges
2100 cycles x 8 hours changing time = 16,800 hours of AC power
0.144 KW x 16,800 hours = 2,419.20 KWH
2,419.20 KWH x $0.12 = $290.30
Initial Product Cost = MQN064 (4AA + charger) @ $29.99 MSRP; Charger $14.99, total battery at $3.75/cell
TOTAL COST OF PRODUCT and RECHARGING = $290.30 + $29.99 = $320.29
TOTAL NUMBER OF RECHARGE CYCLES = (4 batteries x 2100 each) = 8400 recharges
COST PER RECHARGE = ($320.29/8400) = $0.038 (.038 cents PER RECHARGE)
NOTE: Cost of electricity is based on 2013 US average energy costs @ $0.12 per KWH (as calculated by US Engery Information Administration).
Since alkaline cells are non-rechargeable, they must be discarded and then replaced. eneloop batteries deliver best-in-class Ni-MH high capacity power and "rechargeability" combination up to 2100 times. Devices including cameras flash units and wireless game controllers can easily draw more than 1000mA of current; rapidly depleting alkaline batteries power. eneloop batteries maintain a consistently high voltage level keeping your devices operating for a long period of time. When you use eneloop Ni-MH rechargeable batteries, you will realize that "1.2V" can indeed be better than "1.5V".
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.
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.
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
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.
