Yes, the Panasonic eneloop Pro Smart & Quick Charger BQ-CC55 supports the charging of rechargeable batteries with different capacities. This charger features Individual Charge Control technology, which makes it possible to charge up to four AA or AAA eneloop and eneloop pro batteries individually, regardless of their capacity.

You can therefore easily charge batteries with capacities such as 2400mAh and 2300mAh in the same charger, as the charger monitors and charges each battery separately.
