The rechargeable Battery Pack 2 is an external storage cell that is connected to the left of the Game Boy in the socket especially provided for it. It can also be used as a power pack (that is, directly via the socket). It has 2 parts:

a small light gray box = battery set case

a small dark gray box = power pack with power plug


Note:

• When charging, the battery pack can heat up.
