    I'm curious about how long it takes for a quick charge.


    It has four independent channels with the following output: 1.5V 750mAx4(AA) and 1.5V 275mAx4(AAA) batteries.


    If the green LED lights up at 80% charged, how can I tell if the battery is fully charged?


    When the light turns green, the battery is at 80% capacity. When the light turns off, it is completely charged.


    Can it charge the batteries in 3 hours?


    2550 mAh AA Eneloop batteries with this BQ-CC55 charger will charge 1 or 2 batteries in 2 hours, and will charge 3 or 4 batteries in 3 hours.


    Where are these manufactured?


    The package contains 4 made in Japan standard eneloop AA 2000mAh batteries and the new BQ-CC55 3 hour quick charger made in China.


    Does quick charging reduce the life of the batteries?


    I haven't used my Panasonic Quick charger yet, but I want to let you know that a statistician from Cicero, Illinois helped get Japan back on their feet after WWII, and that group decided to pick a product and fine tune it to have zero defects.
