TECHNOLOGY
Retains up to 70%* of its charge after 10 years*
We've improved the metal-hydride alloy lattice inside your eneloop battery so that it retains up to 70%* of its charge even after 10 years* when unused and properly stored. The design also resists voltage drop during discharge and minimizes loss of capacity. Once charged, you can trust eneloop to provide a powerful energy solution, and its long storage life is great in emergencies.
*Capacity based on testing method established by IEC 61951-2 (7.3.2) when stored at 20 °C (based on Panasonic's estimation) and compared with minimum capacity. Varies according to conditions of use and proper storage.
Consistent discharge performance
eneloop Ni-MH AA and AAA batteries maintain a consistent level of 1.2V power throughout the entire life of the charge. While alkaline chemistry batteries rated at 1.5V, the voltage rapidly drops below the NiMH rating of 1.2V and decreases the amount of power going to the device.
Note: The graph opposite shows an AA-size eneloop tested against a competitive AA-size alkaline battery under continuous discharge at 500 mA, 25 °C. Values are approximate.
Lasting power in extreme temperatures
eneloop batteries maintain excellent discharge performance even when used in extreme temperatures. The batteries are rated for use in temperatures down to -4° Fahrenheit, which is great for outdoor activities.
Note: Graph opposite is based on Panasonic’s own testing of AA-size eneloop and a comparable alkaline battery under continuous discharge at 500 mA, 0 °C. Results may vary depending on the equipment used and other conditions.
Note: Operation time will be shorter than operation at room temperature and varies according to the equipment used.
Power that keeps its promise
Keep your devices running at peak performance with eneloop rechargeable batteries. Unlike traditional alkaline batteries that experience a sharp voltage drop, eneloop maintains consistent power throughout its discharge cycle.
This steady power delivery means you'll enjoy a closer, more comfortable shave from start to finish. As our testing shows, eneloop's superior discharge curve provides sustained voltage far longer than comparable alkaline batteries - so you can count on reliable power until the very end of the charge.
