On the front side there are 4 universal space for AA and AAA size batteries. Moreover, when charging, you can combine the elements as you like in size and capacity. You can also add new batteries in the process of charging and remove already charged. And all because the control of the battery charging current in each cell is carried out separately.
The main feature of the Panasonic BQ-CC55 is intelligent charging. The device is able to assess the residual charge and the state of the batteries that you put on charge and flexibly adjust the current parameters for each cell. Due to this feature, the time to fully charge classic batteries is reduced to 1.5 hours (eneloop PRO to 2.5 hours). To control the charging process, the device is equipped with a separate three-color LED indicator for each cell. A steady red signal indicates the charging process is from 0 to 20%, yellow - from 20 to 80%, green - from 80 to 100%.
