ABSTRACT:
A battery compartment for portable electrical equipment such as computers, tape recorders, VCR recorders, camera flash equipment and other such devices has an internal configuration and appropriate electrical connections to receive at least two different types of battery cells which may be of different dimensions. These can include standard dry cell batteries and rechargeable NiCad batteries, for example. The power pickup from the two types of cells is different, so that non-rechargeable dry cells can be isolated from charge when external power is attached to the portable device, while rechargeable cells are not isolated from the charge. The different dimensions are accommodated by orientation of the one type of cell-receiving spaces at right angles to the other type of cell-receiving spaces so that incorrect placement of the cell types is prevented.
