Type B
– This design has a black plastic connector in the wires between the battery and the
baseboard. This makes it unnecessary to remove the riser cards or memory modules. CMOS
batteries with this connector are usually found in later versions of the SFA7700 family (SFA7700X,
GS7K, and ES7K) as well as the battery kit itself. To separate the battery simply detach using the
black connector (Figure 21).
