Panasonic eneloop

Panasonic eneloop is a brand of rechargeable nickel-metal-hydride batteries that can be recharged hundreds of times and hold their charge for years. It began at Sanyo before moving under the Panasonic name.

History

The first eneloop battery went on sale in Japan on 14 November 2005 under the Sanyo name, in AA size with up to 1,000 recharges. Panasonic took control of Sanyo in 2009 and kept the eneloop brand.

The cells retain about 70% of their charge for up to ten years, and cumulative sales reached 500 million units in 2019.
