'eneloop' is a product that proposes a new lifestyle - one without disposing of batteries. Once charged, it can be used repeatedly, and once used completely, it can be recycled. To promote this kind of new battery lifestyle, SANYO developed a world first* rechargeable battery that can be used like a dry cell battery - 'immediately after purchase'. Based on its new vision 'Think GAIA' , SANYO is simultaneously pursuing solutions for a comfortable living and consideration for the environment and would continue providing 'GlobalEnergy Solutions' and 'LOHAS (Lifestyles of Health and Sustainability) Solutions'.

Self Discharge

Eneloop is a new SANYO technology that enables all their Eneloop batteries to enjoy very low self discharge rates compared to traditional rechargeable batteries.



Self discharge is what happens to an electrical charge over time when not in use. 'Self discharge' affects all batteries but is more noticeable in rechargeable batteries.

As a general rule, standard rechargeable batteries lose or 'self discharge' 1% of their charge per day when left unused. For example, rechargeable batteries left in an unused digital camera or a drawer for over 3 months often need to be recharged before use. In comparison, batteries with Eneloop technology lose only 15% of their charge within one full year - maintaining 85% of its original charge.
