8-Pack Panasonic Eneloop Pro AAA Ni-MH 950mAh Pre-Charged Rechargeable Batteries BK-4HCCA

eneloop pro Ni-MH "Low Self Discharge" batteries utilize Panasonic's advanced rechargeable battery technology providing up to 2550mAh¹ of power (AA batteries) and the ability to be recharged up to 500 times².

eneloop pro battery cells deliver consistent power performance, maintain 85% of their charge for up to one year¹, come pre-charged by solar power (at the factory)³ and are ready to use out of the package. These eneloop cells also have increased power, added storage life and extreme temperature performance down to -4 degrees Fahrenheit.⁴

• eneloop 2550mAh typical /2450mAh Ni-MH minimum (AA)¹
• 950mAh typical / 900mAh minimum (AAA)¹
• Hold up to 85% of their charge after one year of non-use¹
• Can be recharged up to 500 times²
• Pre-charged at the factory using power generated from solar energy and ready to use right out of the package³
• Work in extreme temperatures down to –4°F⁴
• Batteries can be recharged when fully, or partially drained
• Ni-MH, Low Self Discharge rechargeable batteries

eneloop pro, Ni-MH rechargeable batteries feature added mAh power, making them the perfect choice for DSLR flash units, game controllers and other devices that require additional power. While eneloop pro batteries were designed to provide more power for high drain devices they will also perform well in conventional devices that require AA or AAA batteries.

eneloop batteries utilize a highly-durable super lattice alloy which prolongs the life of this important material. Improvements to this superlattice alloy have increased hydrogen stability resulting in reduced self-discharge and long lasting, stable voltage output.

Crystal lattice structure of the hydrogen storage alloy

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 500 times².

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. eneloop pro batteries deliver best-in-class Ni-MH high capacity power and "rechargeability" combination up to 500 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".

eneloop pro "signature features" include ready to use rechargeable power with up to 2550mAh (AA) and 950mAh (AAA), the ability to hold 85% of their charge for up to one year (when not in use)¹ , can be recharged up to 500 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 pro batteries can be recharged up to 500 times² , 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+ Call2Recycle.org recycling centers near you.
