Do I need to charge and discharge batteries before use to get optimal performance?
All of our eneloop rechargeable batteries are fully charged at our factories before shipment. However, during shipment, batteries may naturally discharge due to the change in environment or temperature. It is recommended to charge a rechargeable battery before use if the situation allows for it in order to reduce damage to the battery. However, if you have no choice but to buy and immediately use the batteries, feel free to do so. The optimal capacity of the battery will be reached approximately after 2 charge and discharge cycles.
