Panasonic BK-4MCCA4BA eneloop AAA New 2100 Cycle Ni-MH Pre-Charged Rechargeable Batteries

Panasonic BK-3MCCA12SA eneloop AA New 2100 Cycle Ni-MH Pre-Charged Rechargeable Batteries

eneloop Ni-MH "Low Self Discharge" batteries utilize Panasonic's advanced rechargeable battery technology allowing them to be recharged up to 2100 times. eneloop battery cells, maintain 70% of their charge for up to 10 years, deliver consistent power performance, are pre-charged using solar power (at the factory) and ready to use out of the package. eneloop batteries can also operate in extreme temperature performance down to -4 degrees Fahrenheit.

eneloop - The Birth of a New Technology
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 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.

Batteries can be recharged when fully, or partially drained. eneloop charge capacity and mAh estimates based on Panasonic internal IEC 61951-2(7.3.2) testing. Recharge cycles based on testing method established by IEC 61951-2(7.5.1.3). Solar energy charging as certified by The Green Energy Certification Center. eneloop batteries need a charger to be recharged. Panasonic Ni-MH battery chargers are recommended. Recommended storage conditions 68 degrees F. Results may vary based on conditions of storage and use.

New - Longer Storage Life

eneloop 2100 cycle rechargeable Ni-MH batteries now maintain 70% of their charge for up to 10 years (when not in use and stored properly).

Recharge eneloop battery cells up to 2100 times

eneloop's latest version cells can be recharged up to 2100 times. 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 increases the number of times that eneloop batteries can be recharged, up to 2100 times.

Clean Energy from the Factory to Your Device

eneloop's unique "Clean Energy Loop" initiative is a reality. All eneloop 2100 cycle and eneloop pro batteries are pre-charged at the factory in Japan using power generated from solar energy. This process is certified twice a year by The Green Energy Certification Center.

Performance Down to -4 Degrees Fahrenheit

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°F.

What Makes eneloop so Incredible

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.
