eneloop by Panasonic:
Combining the performance and convenience of dry batteries with the cost-efficiency of rechargeable nickel-metal hydride technology, eneloop is the best choice for you and for the environment.
Panasonic eneloop can be recharged up to 2,100 times—top them up whenever you want and in a couple of hours they’re ready to work longer than standard alkaline cells. They even hold 70 % of a full charge after 10 years in storage, so you can count on them in an emergency.
Every recharge saves a battery from the trash. You’re joining millions of others around the world in reducing waste, and making a real contribution to the future health of our planet.
